rather than randomly poking whether a particular type of defrag will speed up access. ![]() Is that the case? Then start narrowing down the cause as to whether it's the disk subsystem and whether it's a problem with your drives being too slow, utilization is wrong for your RAID configuration, etc. In this version of Windows, Disk Defragmenter runs on a schedule so you dont have to remember to run it, although you can still run it manually or change the schedule it uses. The bigger benchmark is whether your server is having performance issues and your users notice. Disk Defragmenter is a tool that rearranges the data on your volume and reunites fragmented data so your computer can run more efficiently. If defragging makes a big difference in your performance, I'd venture a bet that you should be looking at changing hardware a bit. Your best bet would be to run a benchmark before and after running your defrag to get numbers for your particular circumstance on your particular hardware. You're going to have other factors that can't possibly be generalized.most servers you would have to factor in your RAID controller, caching, load, type of RAID, etc. But if you insist on using a 3rd party one, Defraggler might be slow compared to others, but it is the best, as it uses Windows API's and copies the data to the side, before moving stuff around, in case of a power interruption, or you cancel the defrag, your data remains intact, because it uses volume shadow service, otherwise known as VSS. Unless you have a lot of tiny files being written/erased/written to the drive, basic defragmentation should be more than enough on Windows.
