at the moment i have 2 hard drives 160gb wd ide and a 200gb maxtor sata1 (failing of course) just got an asus a8n sli deluxe so was thinking maybe getting a couple of smaller sata2 drives and raiding them for the boot drive and keeping the others as slaves , which would be fastest and is it really that much faster than just one large sata2 and no i cant afford raptors
