Well i bought the rest of my 8 2tb hard drives from bestbuy with a raincheck yesterday and i got em for $74.99 per hard drive. Normal price on tigerdirect and newegg is $160. For you I would recommend at least a terabyte harddrive considering you can get one for about $100 now because of the flood. The price difference from a 500 gig to a 1tb isnt that great atm because of the price hike.
