I've just set up a RAID0 array and it's no faster than my previous SATA1 hdd. I'm using two SATA segate 80Gb drives to create a 160Gb array. ASrock DualSata2 mobo. I haven't seen any great improvement so I installed and ran PCmark05 and it scored ~ the same in both 'xp startup' and 'general hdd usage' tests. I wasn't sure what to set as stripe size, so I went for the default 16K. Am I missing a trick here?
