I have a western digital 80 gig 7200 HDD (WD800JB) and a 120 gig 7200 HDD (WD1200JB) and was wondering if it is possible to get a RAID card and use the RAID 0 option. I dont have the money to purchase another HDD to make a pair for the 80 or 120 but i have enough for a RAID card. Are the performance gains enough to purchase the RAID card? THANKS
