I don't that sort of luxury. The hardware's already out in the field. I have
to make do with what I have. If I go back and tell my client that, yes, if
we have a single-bit failure on a disk sector, our only alternative is to go
to two drives on the card and do software RAID, I'll be fired (and rightly so)
for incompetence.

Such "perfect world solutions" simply don't exist sometimes in the real world.
