I've purchased x8 of these from this Ebay seller in the past 24 hours. He's generally pretty quick to respond, provides pictures of the individual drives upon request, and ships within 4 hours of placing the order. Drives are listed in smaller quantities, but if you'll message him he'll do 4x for $1200. I believe he started with qty 30.
