"I would highly recommend Diskeeper to an Admin looking to improve server performance and reliability. At our location we deployed it on our most critical servers and the difference was quite drastic (that particular server is our mail server).
My biggest fear was that the server would take a performance hit once the software was defragging, but the hit never materialized. In fact the system was noticeably faster after a few days, and after two weeks, a few people asked me if we had moved the mail to a new server.
On the reliability side, that server had 3 drive failures in 6 months prior to Diskeeper being installed. So far it’s been running for 7 months and we haven’t had a single drive failure on any server that Diskeeper is also running on.
When we initially deployed Diskeeper on our NAS (which was just as fragmented as our mail server), it wasn’t defragging because of the intense load the system was under. I called tech support and they helped me modify a few registry keys and the software was working the way it should. And, as on our mail server, there was no noticeable performance impact while it was defragging.
Diskeeper is worth every penny and is one of the few programs out there that does exactly what it says. I could not be happier with the performance and reliability gains we have made since installing Diskeeper.

"Indeed, we are a satisfied customer. We’ve done some testing, and validated what we already suspected – fragmented disks contribute to overall system slowdowns.
We’ve measured several common functions on several systems before and after Diskeeper defragmentation – we found anywhere between 10-15% performance improvement. While 10-15% may sound fairly modest overall, when considering an engineer’s time/value, improving performance by 10-15% for their daily tasks has a significant aggregate benefit to our operation and productivity.
At the same time, we found that Diskeeper’s management is powerful and easy – a “set it, and forget it” scenario that just works.
I’d be willing to give a reference for Diskeeper.

"I first started using Diskeeper on our original Win98 machines to improve their performance and have used it on most of our computers ever since. We now have Diskeeper installed on our servers and on all workstations. Most of our employees also use it at home. They tell me that they LOVE the Professional Edition.
In the office we use the Diskeeper Administrator Edition to control all the workstations and server. We love the alert feature that lets us know when there is problem and then the network administrator can log into the computer that is having a problem and fix it without leaving his desk.
We recommend Diskeeper to EVERYONE that has a computer!

"Sure, I will give references for Diskeeper. I have a small office of about 15 users and Diskeeper is an essential part of my desktop maintenance program. I've used Diskeeper for 12 years and have found it to be the most trouble free, reliable and solid software I have ever used. As it runs in the background, it saves so much time when I do periodic maintenance on my machines.
Diskeeper has robust features and I believe it has contributed to the fact that I have rarely had a hard drive failure in those 12 years. There was some concern about being able to run it with an encryption program, Safeboot, but I have not experienced a single issue with both programs running simultaneously. I would recommend Diskeeper to anyone who is concerned about the health of their systems.
We are definitely seeing the expected return on investment. I find it to be an essential part of workstation maintenance. It has a lot of great features and I'd recommend it to everybody.

"I would be more than happy to be a reference site for Diskeeper!
In general we have been running Diskeeper for 3-4 years now. We are a 99% Windows shop. I have had great success running Diskeeper on every Microsoft O/S. As far as desktops and notebook in our environment (500+) we saw a huge decline in what I would call "no-hardware O/S failures". Meaning that we saw the number of PC’s failing because of O/S problems shrink to near 0%. Not to say that Diskeeper has or can prevent the actually HD from a physical failure but all of our PC’s are much more stable. We have done almost no re-imaging of them because the O/S failed. The majority of our PC’s are remote to us so the simplicity of auto defrag was huge! We can’t depend on our users to do any “maintenance”.
Graphics: we have 50+ users who are running AutoCAD 2007, 2008, and 2009. Plus a few users running Rivet from AutoDesk. We also have a few users who work a lot with the Adobe suites creating marketing materials. I also support 2 users who do video and auto creation and editing. All of these applications work just fine with Diskeeper and I believe perform at their best because of the auto defrag!
Encryption: I do have Windows encryption running on a few 2003 servers and XP PC’s, probably 15-20in total. I have had absolutely zero issues. As we are deploying Server 2008 and Vista, we are deploying Bitlocker at a much higher rate than we ever did before. I would estimate 30+ implementations of Bitlocker running in our environment with Diskeeper 2008. We are going to upgrade everyone to Diskeeper 2009 in the near future.
Virtualization: I have been running Diskeeper along with Windows Virtual Server 2005 R2 for a few years now and it has been perfect. I have seen the effects of not running Diskeeper in a virtual server. I have seen a 20GB image grow to over 100GB simply because there was no defrag process in place!
I just recently brought our first Hyper-V server online and haven’t seen any problems with Diskeeper and Hyper-V.
On the server side I have run Diskeeper on every MS O/S out there with zero problems!
In my opinion Diskeeper is a must have! I don’t have the time or staff not to have this product!

"I can comment about the benefits that Diskeeper has on managing free space and the companion prevention of file/folder fragmentation. I feel that Diskeeper stands head and shoulders above integrated Windows tools when it comes to defragmentation. It’s automatic, always running and has not created any problems or conflicts on our servers.
I would also like to state that running Diskeeper Professional on my desktop has made my system boot up 30% faster, and as I am not a particularly patient man with computers, this is a truly welcome gain. “

"I will be happy to assist with references for Diskeeper. We do use AutoDesk products like AutoCAD with all the plugins and the ability to have defragmentation software like Diskeeper to help speed up the loading of those programs was great.
The one thing that we love about the product is the Diskeeper Administrator. The ability to centrally manage the installations of Diskeeper in our office is great as we have close to 700 machines in many remote locations. Diskeeper installs silently and quickly and the policies propagate seamlessly.
It has been a great experience for us all. "

"I have been using Diskeeper for a while now. It is a great product. I have seen improvements on the PC’s that have Diskeeper compared to the ones that don’t. The speed of the hard disk is improved dramatically.
The InvisiTasking is a great technology and keeps the server running efficiently during the fragmentation process. Diskeeper has the lowest impact on the system performance of any application we use.
The Diskeeper Administrator was a great help in installing the Diskeeper on remote machines.
I would recommend this product to anyone. This is a must have product for all servers and workstations.

"I would be more than happy to provide a reference.
I use Diskeeper primarily on file servers, some of which are domain controllers and exchange servers. Diskeeper allows me to set defragmentation policies (i.e. time frames – 24x7, 5 days a week, weekends only, certain hours, etc) and removes my requirement to have to worry whether the disk is being maintained at the highest possible level of performance or not. The Administrator tool allows me to deploy and remove installations of Diskeeper on machines. I can also run reports and pull disk metrics about machines even if they don’t have Diskeeper installed so I know where to put my installations since we have a limited number of licenses. Diskeeper pulls its weight for the dollar saving time, money and effort.
We are a Microsoft shop with some Linux and Oracle and primarily use Dell PowerPath, EMC SAN, Clariion, Equalogic iSCSI. We also have thousands of Dells in our desktop/laptop environment.

"Backing up to tape used to take 4 hours to back up 20 gigs. After defragging with Diskeeper, it took 2 hours to back up 60 gigs.
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%.
We are very pleased with Diskeeper.

"I have 30+ systems. We installed new systems in the last few months. I installed Diskeeper as a part of the initial setup on the new systems because of the high quality results that we had on our old systems. It will be part of our network specifications from here on out.
The main reason I use Diskeeper is because the first thing I would ask when someone called me about a system running slow was “When did you defrag last?” the usual response was “What is defrag?” or “I can’t remember.” I’d have them defrag and call me back if that didn’t help. 25%-30% of the time, they wouldn’t call back. Diskeeper eliminates that part of my troubleshooting, and helps me help my end users quicker.
I have had a lot less complaints about system slowdowns since I’ve incorporated Diskeeper into our standard installation specs. Since system slowdowns were the highest level of complaints I received, Diskeeper has made my life much more palatable.

"Diskeeper is a No Brainer product. Dependable, inexpensive – set it and forget it.
There is NO impact on performance having Diskeeper running.
Fragmentation is now one less thing to worry about. It’s one of the few products that I can actually say, “set it and forget it”. I have lots of other products that are supposes to be that way – with this one, it’s true.
Prior to installing Diskeeper we were manually defragging our disks. Some of the drives would take hours to defrag and within a few days it would need to be done again (e-mail servers). Installing Diskeeper basically paid for itself within a month by reducing off-hour salaries. In addition, defragged drives perform better and last longer. It’s a no brainer for production machines.
We do run HP Storage Works runs well with Diskeeper.
