Based on some google searching on RAID-6, I find that it seems to be
used to describe two different things. One is very similar to RAID-5,
but with two redundancy blocks per stripe, one XOR and one CRC (or at
any rate two methods are employed). The other sources define RAID-6 as
RAID-5 with a distributed hot spare, AKA RAID-5E, which spreads head
motion to all drives for performance.
Any clarification on this?
