Hi Gracey

You require either mirrored or Raid 5.  With Mirrored you will loose 50% of your hard drive space due to the fact that each file is mirrored onto the other HD with RAID 5  you have a parity bit this tends to take a lot of overhead slowing things down a bit but at least you have more HD to play with.
