It's certainly no substitute for backup, which addresses that and
numerous other failure modes. However, single-drive failures do happen
all the time, and having to revert to your most recent backup can
really, really suck.

That's the theory, but servers tend to be built with the possibility of
sudden resource-consumption surges in mind, above and beyond that.
My bitty box (housing my Web server) was always beefy enough that it
survived a couple of slashdottings without too much strain -- including
back when it was an 64MB-RAM EISA 486 with, yep, a pair of fast SCSI drives.
