Hey speaking of that... I've been obsessed about this for a while but never got a good answer. What defragger will let you position stuff on the drive physically by folder? For example, I want all files for whatever game I'm playing at the moment to be at the start of the disk for fastest performance, and the swap file at the end is a really good idea too since it's rarely touched.
I should also mention, regarding my earlier suggestion: I made a second partition for games and tried 64 KB clusters just for the hell of it. Turns out the benefit of that simply isn't enough (even with a 4-disk RAID-0 with 128 KB strips) to outweigh the fact that the unused space on the first partition (Windows) pushes all the game files further toward the end of the disk, slowing them down. It's really hard to get a fair benchmark since you're usually moving things around in the process and things are changing a lot. You'd have to specifically set out to benchmark it and make sure the positioning remained untouched, then you'd also have to measure real game performance since nothing could really tell you how each game would react to it (other than estimating based on it's average file sizes and most common files accessed.)
I'd really love a defragger that let me manually position certain things and do whatever with the rest. One way I thought to do it was to hack up the layout.ini file since O&O has an option to defrag according to that. But I didn't want to screw anything up with my prefetching.
EDIT: heh a quick google turned up UltimateDefrag... any thoughts
