basically, what i want to know is if there are any speed advantages to raid as opposed to a single SATA drive. i have a seagate SATA 320mb 7200rpm right now, which is more than enough storage but since black friday's supposed to have some killer deals coming i'm thinking about picking up another one. data loss/recovery isn't a huge priority for me, i really don't have shit on my computer besides games, music movies etc. buuut if data moves faster in a RAID array, i would spring for another one if it's cheap. does it?
