For a four-physical-drive setup, I'd suggest: o One drive for OS and software (read once at process startup) o One drive for OS swap file (and data backups, etc.) o One dedicated for photoshop scratch space o One (large) drive for image storage. Sharing one drive for the OS and software installations isn't going to be a problem; anything there will only get touched once. In fact I'd even consider putting the photoshop scratch space on the same physical drive (although on a separate partition) if pushed. The usage patterns don't overlap all that much; the OS/Software gets read at process initialisation time, and the photoshop scratch space is only used once you've got everything started up and have read in some image files. Put the OS swap file & the photoshop scratch disk on separate disk controllers, though. That way you can overlap I/O transfers.
