How might that benefit be realized?
Assume I have 3 disks, /dev/sd{b,c,d} all partitioned identically with
4 partitions, and I want to use /dev/sd{b,c,d}3 for a new SW raid.

What sequence of steps can I take to ensure that my raid is aligned on
a 64K boundary?
What effect do the different superblock formats have, if any, in this situation?
