So why pay extra for software to do something that the drive already does internally? Plus, does the OS even know where data actually is on the SSD, due to drive internal wear levelling? I was under the impression that the drive didn't pass that info back to the OS.
Look at Edit 2. I kind of wonder if it is a bunch of hog-wash too, but I had perfect disk before i owned a SSD. I use perfect disk for my HDD's,...it just so happens that it has some cool features for SSD's that i occasionally play around with. My point was that traditional file defragmentation is bad for a SSD, but some argue (this could be a bit subjective) that some types of defragmentation are helpful. Not all defragmentation software is bad.
Take it worth a grain of salt. If the offical OCZ forum moderator say it might be useful in some situations, than perhaps it is. I can see agruements for and against.
