The one big benefit of PerfectDisk, if their claims are true, is that it can defrag still with a lot less free space than the others. Most you need about 20% free space to defrag properly and I think PD claims it only needs about 5% free.

Caching helps, read ahead, write, adaptive, all help performance, but the fact remains - if the files are not fragmented they are more quickly read from the disk. -- You can't trust your best friends, your five senses, only the little voice inside you that most civilians don't even hear -- Listen to that.

I am not fool enough to take >hearsay as fact. I have backed up my claims with concrete explanations of how file access works, and why fragmentation is rarely has any significant impact with a modern system (as compared to a decade or two ago, when it /did/ have an impact on DOS+Windows systems). I have no intention of wasting my time defragmenting or artificially fragmenting my file systems just to produce numbers for /your/ benefit - even if I did, other people's benchmarks are never as useful as your own measurements on your own system. You have had clear explanations in this thread as to why defragmentation is not a significant issue - even Rod was clear and to-the-point, and unusually restrained in most of his posts. The quotations you posted from your other sources are a mixture of absurd claims ("fragmentation broke my enterprise database"), ignorant and out-dated "facts", and adverts and press releases from defragmentation software companies. Nothing came close to being a sensible explanation of the claimed effects.
