raid1 is trivial to do with just the cpu. Writing is simply writing the
same data to both drives (no calculations requried) and reqding is just
comparing the data (or just read one copy). No need for hardware raid
for raid1 at all.
And from what I've heard, Linux's software raid is more reliable and
simple than most hardware RAIDs.
