okay, i got xp64 installed with raid 0 and used the whole 300gb to try and see what i got for speeds... well, it wasn't anything good. i don't think that it even split the two drives. when i went back in to try it without raid, one of the drives wasn't even partitioned. maybe my head is just too jumbled and i'm not thinking clearly right now, but this is getting annoying. what are you guys getting for speeds with your raptors in raid 0???
