I agree. On a server you should be having mirrored system disks.

For render nodes, or nodes in a compute farm cheap IDE disks are fine.
Just arrange for the swap process to be quick and painless.
In our case, bring down the node, swap the disk and a network install
will format and install to the new disk.

At the other end, think of large storage arrays. I once went to a
seminar by someone in Compaq's storage division, who said hsi dream was
to see a wall of disk drives, and when one failed there is a whirring
noise and the disk pops out. Push in a new one and the free space starts
being used by the array.
