Just run 'mdadm --create /dev/md0 --level=5 --raid-devices=2 /dev/sda1
/dev/sdb1', it's as simple as that. Why? Because I still have four
free bays on that machine, and someday I'll surely want to expand the
disks with RAID5, so better prepare it early than having to do it
again later.

RAID5 with two disks behaves just like RAID1, if you think about it.
Maybe you have a little performance loss since the solution is
unoptimal, but, this being a NAS, I don't really care.
