- Higher throughput compared to standard RAID5

Disadvantage:
- Doesn't protect against double disk failures, but RAID5 also doesn't
Note that you could also do RAID6E.

[1] Yes, there's also an algorithm to select which disk is used for
parity for what block, but that doesn't change the way *how* parity is
calculated.
