The first number is the RAID method being used for the first layer of
protection, so 0+1 is a pair of stripes put into a mirrored volume,
while 1+0 is mirrored disks placed into a stripe.
1+0 guards against twice as many failure scenarios, is more resistant
against multiple disk failures (one per mirrored pair), and requires
less time to rebuild when failed disks are replaced.
