Hi, i want 2 hard drives to put them under RAID 0 configuration, Seagate has RAID EDITION drives, can anyone explainme what are the diferences with the other ones?, I have to decide between Seagate 250GB 8MB RAID EDITION ( a bit cheaper ) or Seagate 320GB 16MB (NO RAID EDITION and a bit more expensive). Wich will you choose? IS RAID EDITION ANYTHING I SHOULD TAKE CARE ABOUT? THX
