Yes, but seen how cheap RAID arrays have become? I know disks are getting
bigger as well, and many people will opt for a single disk, but there may
be more urgent things to fix than something for which a hardware solution
already exists. And lets face it: a database ought to be on RAID
anyway,unless somebody wants to write Tandem-style mirrored disks.... ;-)
