But it does have the advantage of not adding _extra_ things to break. If your
CPU/RAM/disk controller fail you are pretty much dead anyway, and with md you
can move the disks/array to a new system without having to match the exact
controller. With md raid1 you can access any single disk directly if that's all
that still works.

Everything breaks eventually (or has fire/flood/earthquake damage). Backups and
redundancy are the only solution to that.
