I’ve used O&O Defrag for a couple years now, and up until now I was always satisfied, but since O&O Defrag 12 the defrag algorithms seem to have dropped in effectiveness significantly.
Especially the access algorithm seems to be doing exactly squat. Files which are being accessed all time aren’t moved at all, like they are supposed to. Anyway, I ditched the junk and set out to find me another defrag application.
I tried Defraggler, which was very nice but way too simple. I needed more. I tried PerfectDisk, it was better but not what I was looking for. I took a look at Auslogics Disk Defrag, something different, but still not what I wanted.
