Uhhh RAID 1 is your best bet. You get fault tolerance (mirrored) plus
you get a hot spare (3 drives).
This is not true with Linux MD RAID.
It might sound scary to most people, but you _can_ have a RAID 10 with
only 3 drives.

Another thing you want to do is to check if the MD device you created
supports barriers. I know MD RAID 1 does, MD RAID 5 does not, I don't
know about MD RAID 10.
If it does not, make sure you have an UPS.
