RAID 6 covers more bases

RAID technology -- Redundant Array of Independent Disks -- lets you establish varying degrees of data protection depending on the particular requirements of a given application. RAID levels 0, 1, 5 and 10 have been the most widely used, with RAID 5 (rotational parity) reigning supreme for fault tolerance because it allows data on a failed drive to be rebuilt without losing accessibility to stored information. RAID 6 (double parity) provides a higher level of fault tolerance by protecting data on two drives in the event of a failure.
