Diskeeper Server Testimonials

“Internally, here at Microsoft, we all use Diskeeper. Everybody uses it. People who use defragmentation programs use Diskeeper. There is nothing else like it. We wouldn’t use anything else.

“We [Microsoft and Diskeeper Corporation] have great collaboration between the two companies. They [Diskeeper Corporation] provide great training and support.”

We are currently using Diskeeper Enterprise Edition on one of our file share servers, this server is constantly bombarded with changes therefore the drives are always fragmented; your product runs every night to help maintain a low fragmentation, thus prolonging the life of the drives.

The "Set It and Forget It" option is very helpful and we found that the server is performing a lot better; the health of the drives has vastly improved.

The server we run Diskeeper has Win2003 server and it hosts all of our 1738 terminal server user profiles and personal areas. Obviously the server is key to our business. A fast and reliable server is a must and your product helps us to maintain this.

I would recommend this product to people who use terminal servers because all our profile and user file shares are also held on this server and originally many were experiencing slow logons, but after Diskeeper was installed, we found that the overall speed and efficiency of the server improved.

So all in all, we are very happy with the results generated by Diskeeper.

I’m completely satisfied with Diskeeper. We use it on all 50 of our servers, 22 of which are running Citrix Metaframe XP and get trashed every day with users logging in and out constantly all day. Previously we were unable to really use Diskeeper to its full potential. Now with the Administrative Edition we are able to centrally manage and log defragmentation runs nightly. The Smart Scheduling feature is also very handy because I don’t have time to figure out the best time to run defrag on 50 servers especially with nightly backups running concurrently, now this does it for me within the limits I set. Then I can use the reporting tool to easily summarize the result of the night’s defragmentation runs. I’ve also noticed that the engine runs much quicker and is better at optimizing my disks for performance. Even the UI is greatly improved and easier to use.

We are a healthcare corporation with a centralized server network and about 30 WAN locations throughout New England . Our servers are all Windows 2000 with Citrix Metaframe XPe on the front-end. We mostly run Microsoft Office products along with customized clinical and accounting applications.

All in all, this is a pretty complete defragmentation solution which I would recommend to others, from the casual home user to the corporate enterprise.

I manage 100 Windows servers between our three data centers. We use Diskeeper on all of our file/print servers and have noticed a drastic performance improvement (even on dual Xeon servers with 2GB RAM). We also have it running on our internal production SQL Server. We recently upgraded one of our licenses to Enterprise Edition to defrag a Dell PowerVault SCSI drive array. You'd be surprised how much faster GroupWise archives open when your drive isn't 14% fragmented.

We use Diskeeper to manage the disk space on our Dell PowerVault 220S SCSI drive array. It's run on a two-node Microsoft Windows 2003 cluster. Having 1.6TB of disk space has greatly helped us since we kept exceeding capacity and migrating data servers about every nine months.

I'm convinced the only way to efficiently manage 1 TB of active files is with Diskeeper. Manually defragmenting millions of files with the Windows Disk Defrag tool took almost 2 full days to run and ate up about 30-50% of the system CPU. Diskeeper took less than 1 full day to run its initial cycle, and only used 5-9% of the CPU so no one called to ask why the network was running slow. Since we now schedule Diskeeper, it takes about 10% less time to backup the file system. This is very important when your full backup runs more than 24 hours (which is sad with a GB network backplane).

Fragmented file servers took around 16 hours to back up each night, leaving no time for maintenance, virus scan or anything else. [With Diskeeper,] backups now take a maximum of 4 hours!

The problem we were having was, the server would get so busy that it would stop processing I/O requests and network traffic would just hang.  Working with Microsoft and Compaq, we concluded this was due to fragmentation.  When we installed Diskeeper, it resolved the problem overnight and the servers have been running smoothly ever since.

I have found Diskeeper to be less intrusive on other processes while it performs its tasks. Experience with default defragmenters shows that sometimes they will hang or get stuck on a given section of the hard disk.  This is an extremely important problem solved by using Diskeeper over the Windows built-in defragmenter.

Prior to using Diskeeper, I was manually defragging them using the built-in utility which, at one point, caused one of the servers to totally lose its disk MFT configuration and causing me to have to rebuild the entire server.

That's the scoop. Manual defrag stinks and the built-in utility is in no way viable for a server.

Before installing Diskeeper, the computer had to be rebooted on a regular basis because it was slowing down; access to files was always slow, especially when up to 10 people could be accessing the drive. Since I installed Diskeeper the number of reboots has dramatically reduced, file access is much quicker, and whenever I look at the state of the disk there are very few fragmented files. With the PC in action 24 hrs a day, the Smart Scheduling works very well.

I am absolutely, fantastically and completely elated with the value, performance and ROI I have received from my Diskeeper software purchase. Diskeeper paid for itself in less than a day!

I don't have to buy a new PC, thanks to Diskeeper. Diskeeper should be on everyone's machine. After using Diskeeper for a few minutes, my machine was twice as fast....just like it used to be and seems faster than ever before!!!

Keep in mind that I am a computer professional by trade...and therefore I appreciate the value of healthy computing. I therefore periodically defragged my machine...but I could never afford to defrag frequently enough to keep my machine performing at top speed. I just can't afford the time it takes to use the built-in Microsoft Windows defrag system utility. It just takes too long and gets in the way of productive work.

Diskeeper solved all my problems!  Diskeeper's "Set It and Forget It!" mode is a life saver...and I'm not exaggerating!

This is an absolutely wonderful software product that EVERYONE should use.

While I am not in a position to negotiate site licenses for IBM, I believe everyone at IBM and elsewhere should use Diskeeper every night. If you ever find yourself in a position to negotiate a volume purchase for IBM, I would be more than willing to sing the amazing praises of Diskeeper.

Diskeeper ROCKS! And it is absolutely painless, worry-free, automatic and awesome!

I love Diskeeper! What I have observed so far is that Diskeeper v9.0 has transparently prevented disk fragmentation from building up and measurably slowing down our production servers. The ability to prevent fragmentation from building up without impacting the CPU load on the servers has been a key feature of the product.

The "Terabyte" engine is awesome! We run two SQL servers with Raid-5 Arrays of 1.6Tb & 3.75 Tb respectively, with 30% free space. We are running on HP Proliant DL-360 & 380 G3 Servers. Diskeeper v9.0 has proven its ability to completely defragment these arrays in just a few hours. I am both amazed and impressed! The Terabyte Volume Engine solved a performance issue caused by fragmentation. Previously we were unable to defragment the Terabyte arrays and fragmentation was resulting in processing delays of incoming data files. This resulted in our SQL server falling behind during times of high usage.  Now thanks to Diskeeper v9.0, we have breathing room to handle future growth. I am so impressed with Diskeeper on our servers that I purchased a copy for my workstation & am recommending it to all of my co-workers as well as to my manager.

Thank You for an excellent product!

Systems, which exhibited slowdown, have returned to normal speedy functioning with Diskeeper's help. We are using our system to handle a fairly high volume of data involving payroll, human resources and worker's compensation insurance for roughly 10,000 employees.  Payroll processing poses the most mission critical aspect of our business, as well as the most speed sensitive and the least fault tolerant. Your product helps keep our system running smoothly. We are running a two-domain network system with thirty workstations and three servers.  Our systems had experienced performance slowdowns due to fragmentation, and Diskeeper brought them back to normal functioning. It is worth a great deal to me to have the peace of mind I get from knowing that a product of Diskeeper's quality and effectiveness is running on the workstations I am responsible for maintaining.

Diskeeper works great! I did see the expected results. The problem we were having was the server would get so busy that it would stop possessing I/O requests and network traffic would just hang. Working with Microsoft and Compaq we concluded it was due to fragmentation. When we installed Diskeeper it resolved the problem overnight. Both servers have been running since we installed the Diskeeper product with no more network access problems.

We use Compaq, HP servers. Storagetek, and Adic tape libraries. These are just file servers for all of our production data. We have a third server that is used for archive data. The archive server is using a product from OTG software called DiskXtender which we found requires Diskeeper in order for it to work. We installed DiskXtender on our server last April and spent all summer trying to get it to work. In the end one of the main fixes was adding Diskeeper to defrag the drive. That fix led to adding it to the other two servers because they were having a similar problem.

I do recommend Diskeeper to others.

In brief, I can honestly say that Diskeeper is a fabulous product, which facilitates the maintenance of our servers and certain workstations.

Currently we are utilizing the Smart Scheduler on our servers, which has proved to be a true turnkey solution for our organization. I would definitely recommend Diskeeper to all of my colleagues out there in the field.

Diskeeper has rescued me from some major Windows XP NTFS bugs. Without Diskeeper's Frag Guard & Smart Scheduling my hard disk was getting severely fragmented on an hourly basis, causing Windows Explorer to frequently take 6-10 minutes to open a folder or Internet Explorer to take as long to open a browser window.

 Microsoft tech support & I have been struggling with this problem for months with no resolution or explanation of what was causing the problem. The system would also spontaneously reboot on a regular basis.

 Diskeeper's analysis helped me recognize the cause of the problem & provided a workaround to NTFS's shortcomings in less than an hour. Before Diskeeper, I lost thousands of dollars in billable hours. Now Diskeeper keeps things humming.

Diskeeper allows me to override my smart schedule by delaying the defragmentation process by a said number of hours. This is very useful if I have a very busy workload that requires as much processor resources as possible. Defragmentation is absolutely essential and if not performed regularly based on usage will result in a significant decrease in system performance.
