Do note that a failing controller will take down the box, if you are
unlucky; if Murphy smiles on you today, it will also fry both disks.
Of course, this from the guy who uses a RAID based on IDE. And yes, the
IDE bus *does* get really confused if something is wrong with one disk,
as I can add from personal experience...

Frankly, I'm a student too, but quite jealous that you get to play with
actual hardware.

afterboot(8), and probably elsewhere; see /etc/daily) provides a little
more protection against administrator error than straight RAID.
