RAID == Redundant Arry of Independent Disks there are several types of RAID. RAID 0: striping RAID 1 mirroring RAID 2,3 and 4 are no longer used RAID 5 striping with checksums. This requires 3 drives minimum. A part of each drive is used for parity checking. This allows for error correction. If one drive fails you can put in a new one and reconstruct its contents. 2 is a fatal failure.
