I didn't think there was any use to it anymore but I've heard it's a good idea to do it on a big drive so it will have lower seek times. I notice when I open my 120gb HD it takes a couple of seconds for the files to appear. And once in a blue moon I have to worry about skipped frames capturing to huffyuv, I start getting concerned when I hear the drive spinning around like crazy doing two things at once. I'm about to reinstall XP with two 120gb drives. Would doing 3 paritions (about 40gb each) on each drive be ideal or would 2 be enough for performance gains (60gb each)? Thanks for any help.
