"We consider Diskeeper to be an extremely vital tool on all of our computer systems, workstations and file servers. As a high-end printing and mailing company, we deal with extremely large files and databases for our clients. We are using Diskeeper on our SAN as well as on RAID drives on our servers. Diskeeper keeps each of our systems hard drives humming! Fast and efficient file access also means a minimum of wear and tear on the hard drives, increasing uptime and minimizing system maintenance. Diskeeper greatly minimizes the amount of time that we spend servicing our systems. It is one of the only products that we can set up and rarely ever have to think about. Diskeeper just goes about its business, maintaining our drives perfectly. Diskeeper just works, plain and simple!

On my laptop, I can easily tell the difference; after Diskeeper was installed, it runs much cooler to the touch, as my 320 GB hard drive doesn’t work nearly as hard as it used to.

With very large PDF’s, PhotoShop files, graphic images, design files, etc that are modified often, having those files kept in a defragmented state greatly speeds up our systems responsiveness and thus our productivity and profitability."

"The difference is night and day between a drive that has Diskeeper installed and one that does not.

We use Diskeeper 2009 on a variety of platforms and machines. We have some VMware machines running, desktops, laptops, and servers. If we don’t defrag, everything comes to screeching halt. We have used Diskeeper on RAID5, RAID0, and on SANs.

When we used the SANs for data storage for a file server, we had customers complaining all the time about performance. Once we used Diskeeper on the SANs and cleaned up the fragments, all the complaints went away.

One SAN is now a 4TB box used for data storage for our VMware environment. The VM machines all have Diskeeper on them because the applications just run faster when the VM is defragmented; each machine is a file that is created to full size when the machine is built. I guess if you used the option to allocate space as needed; there would be more fragments in the physical environment, but we do not.

We too always hear that defragmenting a SANs is not needed. My personal view is that if there are fragments, defragmenting is needed. "

"The greatest benefit we've seen from Diskeeper is speeding up our data backups on our SAN. One of our volumes is 800GB. It took up to 72 hours to backup that volume. After running Diskeeper for a month we started to see tangible results. We are now down to 47 hours. 72 hours is a very long time. By getting it down to 47 hours we now have a maintenance window on the weekend again!

In addition, the files that we access on that volume respond much faster. I will give references for Diskeeper Server edition."

"I would definitely recommend automatic defrag to other Network Admins. Although we have not upgraded to Diskeeper 2009 Standard/Enterprise as of yet, we rely on it heavily to maintain disk performance on our SAN and local (OS) server volumes. InvisiTasking has been a significant enhancement as far as managing system utilitzation for defragmentation. It is probably one of the biggest reasons why we’ve begun rolling out the desktop version as well to some of our XP/Vista machines (we purchased 100 seats last year).

Diskeeper has extended the life of our storage assets and changed the business focus to storage capacity rather than storage performance. That change alone has the pleasant side-effect of reducing, if not eliminating altogether, Help Desk requests about system performance."

"We are running Diskeeper EnterpriseServer on many systems and multiple platforms. It is running on Windows 2000 Servers, Windows 2003 and 2003-R2, and on Windows 2008.

In our installation we set a specific time and date for defragging a network drive. The reason behind this is our backup software. When the files are being defragged, and moved around, and the backup system happens to hit that drive at the same time, it seems to think that the files are in use, or simply sees them as “open files”, and hence does not back them up. Depending on what server we are looking at, skipping files was not something we wanted.

As we checked further into this, the situation turned out to be a problem of the backup program. The vendor suggested we upgrade to newer version of the software, and our issues should go away. (We are in the process of upgrading.)

We have seen some very good results running Diskeeper on standalone physical servers. One incident is our HR and Payroll System. At certain times, the system was running very slowly even though very few users were attached to it. To make a long story short, I suggested installing Diskeeper on that system. The System Admin and I put the application on one weekend and with no users attached, we ran our first defrag.

The process took a little while to finish since it had not been done before. But come Monday morning, and after users started logging in, some called the Systems Admin and asked if we have replaced our server with a faster one!

Of course the answer was “No”. And he explained that over the weekend we defragged our server and databases and manage to achieve a better system performance.
We have installed Diskeeper on multiple other systems and servers. We also started adding Diskeeper to some virtual servers. So far all is running very smoothly. And of course I have no problems recommending Diskeeper to other System Administrators, for their systems. The built-in scheduling and off-hours defragmenting is very helpful and very flexible. Diskeeper has provided us with more system versatility and better throughput than other defrag products. We will continue to use Diskeeper. "

"We do believe that Diskeeper plays a vital role in maintaining our desktops. We encourage our employee owners to run their Outlook client in cache mode and to also use the auto-archive feature. As you know, the built-in defrag does not handle defragging cached mail all that well. So it is important that we keep our desktops defragmented"

"I consider Diskeeper a vital tool in my administrative arsenal. We have fewer complaints from users about their laptops being sluggish. Trust me when I say it saves me time in administration with more than one third of our company’s users having laptops."

"We greatly appreciate the ease of use of Diskeeper software. It eliminates another job from our schedule. It really is set it and forget it, and users do not even know it is there.

It is simpler than the software we used in the past to administer. We have not been bothered with frequent updates to install, or bug issues.

We would recommend Diskeeper for any companies use."

"We do find Diskeeper to be vital and we use it for our virtual servers (VMware) as well. We redirect our user desktops and My Documents folders to network shares and have found the response times improved quite a bit after defragging the virtual server.

We also found that it cuts the time needed to perform a P2V (convert physical machines to virtual) by about 90% if the physical server is defragged beforehand. Case in point, we had a few physical Citrix servers that simply did not want to P2V but simply worked as expected after defrag and very quickly.

Thank you Diskeeper."

"I have always considered Diskeeper to be a vital component for my desktop experience as NTFS volume fragmentation has historically been a real problem in terms of the impact it has on overall system performance. Diskeeper has always risen to the challenge of handling and eliminating such nuisance fragmentation in a powerful, yet efficient manner. I have always recommended Diskeeper to friends, family and colleagues for the robust architecture I have come to know and the innovative technologies employed to keep my NTFS volumes healthy and efficient. Diskeeper helps keep my systems operating at their maximum capacities by providing what I consider to be a key component to overall efficient and productive systems.

I would say, on those desktops where Diskeeper is installed and managed, that we get fewer complaints when it comes to system-wide degradation of performance. I feel that we can safely attribute some of that to our management of the systems and most definitely part of it to Diskeeper's robust management of the fragmentation of the file system. In comparison, those systems without Diskeeper installed and managed do not necessarily perform as efficiently as those that do."

"Diskeeper is absolutely essential to our production systems. I would not deploy a production server without it. The long term difference in performance in our system is not only measurable, it’s noticeable to the end users.

We have a web-based automotive industry CRM with thousands of users. As an n-tier application, the performance of each layer is critical to the overall user experience. Application queues, message queues and data queues are all disk-based. Fragmentation in these critical files will affect performance faster than almost anything else. Diskeeper cut the average page build times by 70%, with many in the sub-second range. These are data-intensive pages, so the performance is very impressive. "

"I've been using Diskeeper for several years now. It's software that has a mission and it does it very well. I like it and keep using it because: It does a significantly better job at defragging than the built in Windows utility. Windows defrag is limited in what it can do Diskeeper does a much more thorough job and defrags where windows can't. It's VERY FAST. If you ever tried to defrag a hard drive in Windows 98, 2000 or XP, you know that you can usually take a long coffee break waiting for it to complete (frown). Diskeeper will continually work in the background monitoring the situation and defragging as needed to keep peak performance."

"We consider Diskeeper to be a vital tool. Our networks run 24x7x365 to support our airmen across the globe. As such, we need our servers to be maintained at optimum levels to avoid any delays or even worse, downtime for the users. Before we had to schedule downtimes and assign personnel to perform the manual defrag. Using Diskeeper keeps the servers from bogging down with all the database activity we have going on. Plus it defrags in the background without affecting active system resources and does it all without anyone running the program.

The other thing I've noticed is that Diskeeper saves us in hardware costs. We aren't adding memory or disks to improve our performance anymore.

We didn't buy Diskeeper specifically for any one application. We knew the value of defrag and were excited to find that Diskeeper met our needs and beyond. Diskeeper has kept up with the new technologies we've incorporated into our enterprise network - RAID, clustering, SAN, and VMware ESX. We aren't worried that Diskeeper will not keep our storage running at its best; it's a proven product that we have quite frankly taken for granted and is part of the fabric of our enterprise."

"Diskeeper is a vital tool. The systems that directly benefit from Diskeeper are my Windows 2003/2008 servers. My work is better because of the performance increase I receive from my servers by having their hard drives defragmented, and the reporting feature also alerts me to storage capacity problems.

I found that the alert feature of Diskeeper is really great. It emails me a report at 9:00am every morning with a disk space and defrag report, so I can be alerted to potential problems. The product was very easy to install and configure as well. And the fact that it works on Windows Server 2008 shows me that Diskeeper is ahead of the curve in the development department.

I will recommend automatic defrag to others."

"I think Diskeeper is necessary to ensure that defragmentation is not an issue. It’s an easy way to have one less thing to worry about.

We are running Diskeeper on all of our servers with RAID, a few NAS servers, and also the box with our antivirus running on it.

I can’t state hard figures on performance metrics, but anecdotally, I had seen a difference when I initially installed Diskeeper a few years back. I am certain that I would not be getting the good performance today without Diskeeper as my machines are over 5 years old at this point. They are just faster all around.

My desktops are also running much better than they would be otherwise. I am still getting use out of Dell Dimension 2400's that also are over 5 years old. I attribute this to Diskeeper keeping their HDs optimized."

"Diskeeper is employed on our servers and user computers and is set to automatically defragment each computer's disk drives. I find the continuous defragmentation to be helpful in maintaining the I/O of the drives at an optimal level, particularly for the servers. As we are a data management company, our servers experience a great deal of read/write operations and Diskeeper helps ensure each drive maintains its ability to process write and read requests in the best manner possible.

Diskeeper benefits the overall operation of our servers since most of the servers are very write intensive (database server, email server, file/print server).

The Diskeeper engine is not CPU intensive and I have observed that it backs off under periods when server or user computer activity is high. Once the activity subsides, Diskeeper returns to processing.

As we do consider Diskeeper to be a vital tool, we have made it a requirement for each computer that is used within our company."

"We are currently using Diskeeper automatic defrag on 12 servers. We consider Diskeeper to be vital to the health and well being of our systems. With automatic defrag, it is one less thing off my plate. It works seamlessly. We have a lot of files that get modified frequently, so our file servers were really a mess before we turned on the automatic defrag.

I have a contractor who comes periodically and his comment was he wished more of his clients would make the investment in Diskeeper."

"I would love to share some thoughts on Diskeeper Server edition. In answer to your questions, I do consider Diskeeper to be an extremely vital tool. The ability to set and forget it, as well as the improved speed over the built-in defragmenter, are just some of the pluses.

I also like the ability to schedule the individual drives and see reports of what has been going on.

My own work is much better because I don’t have to log in after hours just to run the built-in defrag and then wait because it doesn’t play nicely with open files. The speed of our virtual guests and hosts and increased dramatically as well as our biggest file server that serves 170 users.

We are running NextGen HER which generates hundreds of files daily, but we don’t have to worry because every night Diskeeper “puts them in their place!”

Keep up the good work!"

"Diskeeper is a vital tool. I believe that all my applications benefit from Diskeeper.

My own work is better off because Diskeeper takes lots of time off from scheduling jobs and guarantees that my disk arrays will be fragment free, unlike Microsoft's embedded defragmentation tool. I also like the quality of your products. Diskeeper finds more fragments and gives better analysis.

I currently use Microsoft Virtual Server 2005 but am testing Microsoft's Hyper-V and VMware Infrastructure. I also have VMware workstation and use it religiously. We use RAID 1, 10, 5 and 6. I'm also running Diskeeper on two NAS appliances.

I do know for sure that all systems suffer from fragmentation - even domain controllers. With so many Microsoft security updates and file read/write/creation, I can't see how any system can remain defragmented."

"Diskeeper is definitely a vital tool that increases and improves performance, especially in database environments. We utilize Diskeeper on all of our servers. It works well, does the job and we are pleased with the results.

My own work is better off because I’m no longer worried about file fragmentation and I know that my servers operate at peak performance.

The primary reason why we wanted Diskeeper was because we run SAP ERP on MS SQL and Diskeeper does a very good job in defragmenting database data and log files. We wanted to increase the SAP response time by having a defragmented database and Diskeeper helped us reach this goal.

We use EMC Clariion SAN and Diskeeper defragments 200 GB of data from the SAN very efficiently, without impacting the server performance. In addition to defragmenting databases, Diskeeper also helps us with file system fragmentation. Everything runs on RAID5 and RAID10 in our environment and we utilize Windows 2003 R2 Server OS."

"About 5 weeks ago I decided to try an experiment that was recommended by a reader. The basic was to defrag my system and than not to do any defragging for one month. Right after I decided to try this experiment I received a free evaluation copy courtesy of Diskeeper who provided me with a free copy of Diskeeper Pro Premier 2009 to try on my Vista laptop, which I used for the experiment.

My laptop is used through out the day for blogging, searching out sites and for playing with a variety of different software to test and review. So on about February 15th, 2009 I defragged by system using the Diskeeper product I mentioned above and did so for 5 days straight. On or about February 20th, 2009 I stopped defragging to see what would happen.

For the first few weeks I didn’t notice much at all happening or I may not have been watching what was happening. But it was last week that I noticed a few things. I was going into Accessories - System Tools - System Information and I sat staring at an hour glass for about 10 seconds before anything came up. Strange I thought. When I opened some doc’s, same time warp but under 10 seconds and not so severe as above. This is when I noticed that even returning from hibernation also seemed slow. Was it my perception or were things really slowing down? A few more experiments and yes, things were slow. I finished out the remainder to my time and than defragged this morning.

All is once again well. Documents open quickly and I just tried system information and it came up immediately.

Does defragging really help a computer system? I believe it does but your mileage may vary."

"Here is my experience with Diskeeper 2009. We have 2 NAS units that we use for daily backups as well as storage. Because of the large amount of data going in and out of the units, we were having delays in read/write times. The NAS units are used to store backups and user Home folders; the servers are Dell PowerVault NF500.

When we got Diskeeper, the Servers were completely fragmented. Now they are in a much better state and I don’t even have to manage them. Since getting the product I also discovered our other Servers were not in the shape I thought they were in and Diskeeper has helped me clean them up as well.

I don’t know if I can give you a monetary value on this; it’s more a pain level. The server was failing on backups at least twice a week. Some of the reasons that the server was failing, were because of disk read/write errors due to fragmentation. Now that the errors are fixed, I don’t have to spend my morning fixing the backup strategy."

"Diskeeper 2009 has been doing a great job for me and the improvement on system performance makes it well worth the money.

Fragmentation of the virtual disk on VMware virtual machines happens more frequently then on a physical drive. VMware does have a solution but it is time consuming, inefficient and impractical. I use Diskeeper on our VMware virtual machines which had been barely functional before the deployment.

Here are the steps posted to resolve the fragmentation issue:

Like physical disk drives, virtual disks can become fragmented. Defragmenting disks rearranges files, programs, and unused space on the virtual disk so that programs run faster and files open more quickly. Defragmenting does not reclaim unused space on a virtual disk; to reclaim unused space or shrink the disk.

For best disk performance, follow these steps:
1. Run a disk defragmentation utility inside the virtual machine.
2. Power off the virtual machine, then defragment its virtual disks from the virtual machine settings editor (VM > Settings). Select the virtual disk you want to defragment, then click Defragment. 3. Run a disk defragmentation utility on the host computer. Defragmenting disks may take considerable time.

Note: The defragmentation process requires free working space on the host computer's disk. If your virtual disk is contained in a single file, for example, you need free space equal to the size of the virtual disk file. Other virtual disk configurations require less free space.

This was not acceptable because of the frequency (every 3 days or sooner) you would have to do this, and the defrag utility was no more that a Windows-based defrag utility.

We needed a more robust and versatile solution, one that worked well and could be scheduled. I currently use Diskeeper on all of our workstations to maintain optimal disk performance and the Diskeeper 2009 Administrator made the deployment easy."

"I am convinced that it is in the best interest, regarding efficiency & time, for employees to not have to be any longer concerned about their machine operating sluggishly due to the need to defrag. Diskeeper’s automatic defrag is a real time saver and thus never enters the troubleshooting list as a possible cause of problems because you know that the system is being continuously defragged.

People cannot be depended upon to utilize the defrag utility available in XP Pro OS or to use the free Diskeeper Lite on a regular basis. And when it was (very rarely) used it did not do a sufficient job of defrag as you had to run it several times and even then it was always lacking in a complete defrag, not to mention it took away production time because you had to run it either during your work time if the computer got to be so slow that it was imperative, or you ran it over a lunch period/overnight. Even then it had to be run over again when you returned. Suffice it to say that was always a real headache to deal with simply because it is not automatic and did not run in the background.

I would add that it is very important for any system administrator to also purchase the Diskeeper Administrator along with the Server and the workstation versions. This is important because all functions regarding Diskeeper Professional can be administered from the system administrator’s workstation – even across the internet to remote locations."

"I think most all of our applications benefit from Diskeeper but one that comes to mind immediately is File Serving. We have several large file servers that have DAS RAID5 arrays attached to them and I have definitely noticed a difference as compared to before Diskeeper, even at our rapid rate of growth. Also I have noticed a performance perk on our Sharepoint 2007 servers; this would include a heavily-loaded SQL2005 backend.

We are running Diskeeper on our virtual environment servers which are VMware Server 1.8 and 2.0 platforms. I was hesitant about deploying, thinking that large file instances may be an issue with overhead at first, but Diskeeper made all the difference in the world. I can now get away without having to dedicate disk spindles to VM instances. This seems to be doing well with VMware instances on the same spindle as long as I am running Diskeeper.

There are several old servers in our environment that I don’t have to immediately replace because I can get some extra life out of them as long as I have Diskeeper to keep the disk performance tuned.

I like the Diskeeper 2009 Premier also; it's great for my laptop. I insist on running Diskeeper 2009 in our environment. I am a firm believer in Diskeeper and have been for many years. Keep up the great work."

"We’re not a large company; we have approximately 70 employees but we use programs and applications that require large amounts of resources, including a CAD program, Adobe CS4, Sketchup Pro, and other civil engineering applications.

What we’ve found is that with Diskeeper Professional running, especially on our heavily used production stations, we don’t need to waste unnecessary time defragging each one individually. We don’t have a way to easily measure the performance increase, but I CAN tell you that the complaints from users of slow performance have dropped considerably.

We do see a noticeable improvement with our CAD program, since some users have multiple drawings and tools open on their two monitors. Also, the people who use CS4 have made positive comments.

Overall, the increase in performance and speed has well justified the cost of Diskeeper Pro on the workstations and Diskeeper Server on our servers."

"I have a couple programs which cause plenty of fragmentation, but this wades through them like a hot knife through butter. Set it and forget it is the best way to go, yet it's no slouch at on-demand defrags. The new engine is fast and nimble. Diskeeper 2009 is light years ahead of the 2008 version.

I’ve been running it on my laptop ever since I got it and I’ve yet to experience ANY hard drive/disk errors or problems, whereas on my desktop (prior to moving to my laptop) I would go through 2-3 hard drives per year at least. Faults, errors, corruptions or full disk failures were rather common."

In the last year SQL backup speed has improved by > 300%
SQL backup reliability has improved by >600%
SQL maintenance scripts, where applied, improved performance by >4000% (those scripts had had no effect on our fragmented databases)
and SQL-related MOM alerts decreased by >90%.

Je recommande absolument Diskeeper. Diskeeper et Invisitasking, depuis la version 2007, était vraiment EXTRA ! Diskeeper 2008 avec Invisitasking et I-Faast est encore mieux !

Mes systèmes fonctionnaient déjà bien plus rapidement avec les anciennes versions de Diskeeper.
Ils fonctionnaient encore plus rapidement avec moins d’activité avec Diskeeper 2007 et invisitasking.
Mon système fonctionne encore plus rapidement depuis que j’ai installé Diskeeper 2008 avec Invisitasking + IFAAst, c’est incroyable !

Diskeeper peut aider à faire des économies grâce aux gains de productivité et à l’allongement de vie des ordinateurs portables.

Je suis vraiment impressionné par Diskeeper 2008. J’avais deux serveurs qui avaient des problèmes importants avec nos logiciels de sauvegarde. Les serveurs tombaient en panne à chaque fois que le programme de sauvegarde s’exécutait, et les sauvegardes sur le deuxième serveur n’aboutissaient pas.

Entre Diskeeper et Chkdsk, ces deux problèmes ont été réglés.

Grâce à cette expérience, j’ai décidé de commander 5 licences serveurs dès maintenant et prévoit d’en acheter encore plus dans le prochain budget.

J’ai commence à m’intéresser a Diskeeper quand mon disque dur s’est retrouvé énormément fragmenté. Je n’avais jamais fait l’expérience de telles pertes de performance. Le défragmenteur intégré dans Windows XP SP2 ne réglait pas du tout le problème. Apres quelques recherches sur les différents défragmenteurs j’ai acheté Diskeeper en ligne. Ça a mis un peu de temps mais l’application a réussit à restaurer les performances de mon PC comme elles l’étaient auparavant.

Depuis, j’ai réinstallé mon système d’exploitation et mes applications. Je me suis débarrassé du reste et j’ai re-installé Diskeeper. J’utilise aussi l’anti-virus ESET NOD32. Mon ordinateur est maintenant plus rapide qu’à l’état neuf.

Normalement, la vieillesse prend le dessus sur la jeunesse mais, mais pas cette fois. Je me suis entretenu avec mon fils qui considère que les autres défragmenteurs consomment trop de ressources. De temps en temps je vérifie mes disques (2 SATA’s de 250 GB et un disque dur externe de 320GB) et Diskeeper les maintient a un très faible niveau de fragmentation.

Pour résumer, je suis très content du produit et le recommande dès que j’en ai l’opportunité.

Depuis que j'ai pu enfin tester le Diskeeper 10 Home, je suis totalement convaincu. A tel point, que je l'ai acheté sans hésitation dès ce soir, avec le programme de maintenance pour 1 an .(commande 72276515) Le téléchargement, l'installation et la programmation du produit acheté se sont passés comme dans un rêve et les analyses faites avec celui-ci ont confirmé le travail effectué par le produit test. Mon ordinateur a de fait retrouvé une 2° jeunesse. Compte tenu que votre intervention attentionnée a contribué au processus de décision, je tenais à vous le faire savoir et je vous remercie encore. D'ailleurs, je n'hésiterai pas à recommander vos produits et services à mes amis et relations et je vous autorise, ainsi que votre société à vous servir de ce message à toutes fins utiles.

Diskeeper me permet de modifier le planning de défragmentation programmé en retardant le processus de défragmentation du nombre d'heures spécifié. Cette option est extrêmement pratique en présence d'un planning de travail particulièrement chargé nécessitant toutes les ressources disponibles sur le processeur. La défragmentation est absolument essentielle et, si elle n'est pas exécutée régulièrement en fonction de la sollicitation du système, risque de réduire considérablement ses performances.

Nous utilisons actuellement Diskeeper Enterprise Edition sur l'un de nos serveurs de partage de fichiers. Ce serveur est constamment bombardé de modifications et les disques sont systématiquement fragmentés. En exécutant votre produit chaque soir, la fragmentation est maintenue à son strict minimum pour prolonger la durée utile des disques.

L'option « Set It and Forget It » est extrêmement pratique. Nous nous sommes également aperçus que le serveur est bien plus performant et que l'état des disques s'est considérablement amélioré.

Le serveur Diskeeper est équipé de Win2003 Server et héberge nos 1 738 profils d'utilisateurs Terminal Server et domaines personnels. Il joue bien évidemment un rôle stratégique dans nos activités. Il doit être rapide et fiable et votre produit l'y aide à y parvenir.

Je n'ai aucune hésitation à recommander ce produit aux utilisateurs ayant recours à des serveurs Terminal Server parce que tous nos profils et nos partages de fichiers utilisateur sont également conservés sur ce serveur. La lenteur observée à l'origine a disparu dès l'installation de Diskeeper et la vitesse ainsi que l'efficacité globales du serveur se sont améliorées.

Pour résumer, nous sommes extrêmement satisfaits des résultats fournis par Diskeeper.

La sauvegarde des serveurs de fichiers fragmentés demandait chaque nuit 16 h environ et ne laissait donc aucun créneau de libre pour la maintenance, les analyses de virus ou toute autre tâche. [Avec Diskeeper], les sauvegardes ne prennent maintenant pas plus de 4 heures !

Notre problème venait du serveur sollicité à tel point qu'il finissait par cesser le traitement des E/S et par bloquer le trafic réseau. Avec la collaboration de Microsoft et Compaq, nous en sommes arrivés à la conclusion que le problème provenait de la fragmentation. L'installation de Diskeeper a résolu ce problème du jour au lendemain et les serveurs sont depuis parfaitement performants.

Diskeeper est à mon avis plus discret dans son travail que les autres processus. L'expérience avec les défragmenteurs par défaut montre qu'ils arrivent parfois à se bloquer totalement ou sur une section particulière du disque dur. Il s'agit d'un problème extrêmement important que Diskeeper, contrairement au défragmenteur interne de Windows, parvient à résoudre.

Avant d'installer Diskeeper, l'ordinateur devait être redémarré à intervalles réguliers en raison de son ralentissement ; l'accès aux fichiers n'avait jamais été particulièrement rapide, en particulier lorsqu'une dizaine de personnes tentaient d'utiliser le disque sur lequel ils figuraient. L'installation de Diskeeper a réduit considérablement le nombre de redémarrages. L'accès aux fichiers s'est également accéléré et, en examinant l'état du disque, rares sont les fichiers fragmentés. Avec un PC sollicité 24 h/24, la planification Smart Scheduling est extrêmement pratique.

Je suis absolument, incroyablement et totalement ébahi par la qualité, la performance et la rentabilisation de l'achat du logiciel Diskeeper. Diskeeper s'est rentabilisé en moins d'une journée !

Grâce à Diskeeper, je n'ai pas besoin d'acheter un nouveau PC. Diskeeper devrait être installé sur toutes les machines. Après avoir utilisé Diskeeper pendant quelques minutes, ma machine était déjà deux fois plus rapide... autant qu'à l'origine, voire même plus !!!

Professionnel de l'informatique de par mon métier, j'apprécie tout particulièrement l'importance d'une informatique saine. C'est pour cette raison que je défragmente ma machine à intervalles réguliers... sans avoir jamais pu me permettre de la défragmenter aussi souvent que je le souhaitais pour maintenir des performances optimales, du moins jusqu'ici. Je ne dispose pas des délais nécessaires à l'utilitaire de défragmentation système de Microsoft Windows pour faire son travail. Il demande tout simplement trop de temps, au détriment de la productivité.

Diskeeper a résolu tous mes problèmes ! Sans exagérer le moindre du monde, le mode « Set It and Forget It! » de Diskeeper est une véritable bouée de sauvetage !

Il s'agit d'un logiciel absolument indispensable que TOUT LE MONDE devrait utiliser.

Sans être en position de négocier des licences de site pour IBM, je suis d'avis que tout le monde dans notre société et partout ailleurs devrait exécuter Diskeeper chaque soir. S'il vous arrivait, à vous, de devoir négocier l'achat de plusieurs licences pour IBM, je n'aurais aucune hésitation à faire l'éloge des talents extraordinaires de Diskeeper.

Diskeeper fait TOUTE la différence ! Et il s'agit d'un produit convivial, automatique et sans souci, totalement impressionnant !

J'adore Diskeeper ! D'après ce que j'ai pu observer jusqu'à présent, Diskeeper empêche la fragmentation de disque de s'aggraver et de ralentir considérablement nos serveurs de production et ceci, de manière totalement transparente. Empêcher la fragmentation de s'aggraver sans incidence sur la charge de travail des processeurs est l'une des fonctionnalités essentielles de ce produit.

Le moteur « téra-octets » est véritablement impressionnant ! Nous utilisons deux serveurs SQL équipés d'ensembles de disques Raid-5 de 1,6 et de 3,75 To respectivement, avec 30 % d'espace libre. Ils sont exécutés sur serveurs HP Proliant DL-360 et 380 G3. Diskeeper a montré qu'il est capable de défragmenter totalement ces ensembles de disques en quelques heures seulement. Je suis à la fois surpris et impressionné ! Le moteur TVE (Terabyte Volume Engine) a résolu un problème de performance provoqué par la fragmentation. Jusque là, nous n'étions pas en mesure de défragmenter les disques de plusieurs téra-octets et la fragmentation provoquait des délais dans le traitement des fichiers de données reçus. De ce fait, notre serveur SQL prenait du retard lorsqu'il était extrêmement sollicité. Grâce à Diskeeper, nous disposons désormais de la capacité nécessaire pour gérer notre future croissance. Diskeeper m'a tellement impressionné sur nos serveurs que j'en ai acheté une copie pour mon poste de travail et je le recommande à tous mes collègues, ainsi qu'à mon manager.

Merci de nous avoir fourni cet excellent produit !

Les systèmes dont les performances avaient ralenti ont retrouvé leur fonctionnement optimal grâce à Diskeeper. Notre système est utilisé pour gérer des volumes relativement importants de données impliquant les salaires, les ressources humaines et les assurances d'indemnisation professionnelle de 10 000 salariés environ. Le traitement des salaires, qui constitue l'un des aspects les plus critiques de notre activité, est également le domaine le plus exigeant en terme de vitesse d'exécution et le plus sensible aux pannes. Votre produit nous aide à faire fonctionner parfaitement bien notre système. Nous utilisons un système réseau à deux domaines regroupant 30 postes de travail et trois serveurs. Diskeeper a eu raison du ralentissement provoqué par la fragmentation sur ces systèmes pour rétablir des performances optimales. Pour moi, il est important de ne plus avoir à me soucier de la maintenance des postes de travail dont je suis responsable, sachant que je peux me fier en toute tranquillité à la qualité et à l'efficacité de Diskeeper.

Diskeeper est devenu pour nous le ressort principal de tous les ordinateurs. Depuis qu'il est installé et utilisé, nos ordinateurs sont devenus bien plus fiables et bien plus rapides. Au sein de notre entreprise, Diskeeper est en quelque sorte le mécanicien invisible dans un garage.

Il demeure actif en permanence pour s'assurer, à notre insu, de la stabilité des machines et éviter toute incidence sur nos activités. Je n'ai aucune hésitation à recommander Diskeeper à tout utilisateur professionnel dont le temps est compté et qui apprécie tout autant ses heures de liberté que ses heures de travail.

Arthur Wray

Nous sommes extrêmement satisfaits du logiciel Diskeeper que nous avons installé essentiellement sur les postes de travail audio gravement affectés par une augmentation excessive de la fragmentation. Nous l'utilisons en mode de veille et apprécions tout particulièrement le fait qu'il se charge de tout le travail dont un opérateur ayant besoin de s'arrêter est responsable, tout en maintenant la stabilité des ordinateurs.

Il s'agit pour nous d'un produit stable que nous continuerons à utiliser et à recommander.

Diskeeper fonctionne parfaitement bien. Il a réellement contribué à optimiser les performances de nos serveurs de fichiers. Le planning de défragmentation « Set It and Forget It » facilite la gestion des ordinateurs. Je suis en effet responsable de 100 serveurs Windows répartis dans nos trois centres de données. Nous utilisons Diskeeper sur tous les serveurs de fichiers/d'impression et avons remarqué une amélioration considérable des performances (même sur les doubles serveurs Xeon dotés de 2 Go de mémoire RAM). Permettez-nous de vous remercier une nouvelle fois de nous avoir offert un produit aussi exceptionnel.

L Snyde

Le programme Diskeeper Server fonctionne parfaitement bien et exécute la défragmentation au démarrage des répertoires. Je suis extrêmement satisfait de l'amélioration des performances. Il s'agit désormais d'un outil indispensable sur mon système.

Nic D. Barlow

En résumé, je peux affirmer en toute honnêteté que Diskeeper est un produit exceptionnel qui facilite la maintenance de nos serveurs et de certains de nos postes de travail. Nous utilisons actuellement la fonctionnalité Smart Scheduler sur nos serveurs pour disposer d'une solution « clés en mains » réelle dans notre organisation. Je n'ai aucune hésitation à recommander Diskeeper à tous mes collègues sur le terrain.

Carlos Almeida

Je suis une inconditionnelle absolue de Diskeeper que j'utilise depuis que j'ai découvert la version 4. En fait, je n'installe aucun poste de travail ni serveur NT pour mes clients sans l'équiper d'abord de Diskeeper. Votre logiciel fait aussi de moi un héros dans la résolution des problèmes de performances sur les serveurs devant lesquels la concurrence est impuissante, tout simplement en vendant, en installant et en réalisant la première exécution de Diskeeper. Merci de cet EXCELLENT PRODUIT !!!!!!
