Re: mirroring raid arrays

RAID 0+1 is not RAID 10 (or 1+0). The end result is the same, but the
implementation is different.

Here is a great site that discusses combining multiple RAID levels for
speed and paranoid redundancy:
http://www.pcguide.com/ref/hdd/perf/raid/levels/multLevel01-c.html

The site even talks about RAID 5+1 arrays.
