I've read the raid(4) and raidctl(8) man pages, and neither really answers
this simple question:

I have two disks, I want to be protected against one of them failing, so
some sort of mirror or redundancy is required. It looks like RAID level 1
(mirror), or RAID level 5 (striped with parity distributed over components)
are the obvious possibilities; what are the advantages and disadvantages of
each?

NetBSD's documentation should cover configuration questions like this,
particularly for a new facility like the RAIDframe driver...
