I have used all three Diskeeper, PerfectDisk, and O&O Defrag.

I didn't use Diskeeper much but I didn't like it because there was no way to optimize the defrag. (arrange the files in a certain way to increase access time).
I also didn't like the way that even after defragging several times the files appeared to still be "spread out". (didn't consolidate the free space very well).

I used O&O version 4 for quite a while and really liked it.
It was damm slow but seemed to do quite a good job, it could take up to an hour per gig for a complete optimization the first few times but I would start it up before going to bed. I tried the new version 6 and it was much faster but unless I'm stupid I couldn't find a way to do an offline defrag of locked files unless I scheduled a defrag job.

I recently started using perfect disk a couple weeks ago and I really like it.
It's very fast, optimizes the files by access date, and does a very good job of consolidating the free space. (seems to me that without all the "holes" the drive shouldn't fragment as quick).
It seems to be working very well so far.

PerfectDisk with my vote. Very fast with nice options to choose for scheduling and defragging. Tried most all of the listed and this is the best IMHO.

I thought I should let everyone know which program I decided to go with. I decided to go with Diskeeper 8.

So far so good... Everything seems to run nicely... Setup was easy enough. Thanks for the suggestions! :)

I rarely defrag. But I lilke O&O best of the defraggers I've tested. I don't have it installed on any of my 4 pc's right now, because frankly I renew/retore my partitions more often than defragging is necessary.

Why you have to pay for such a utilitie when you can do a fine job with the derfag.exe that comes with windows?And if you like to defrag the pagefile or the registry hives there is this freeware defrag utilitie from sysinternals.

I think is enough at least for me.

O & O !

definitively :lol:

for me is the best: with nice clean interface, you can use your pc while it runs and much more

O & O rules! :ph34r:
