There's an even *more* interesting paper on this from a CMU post-doc
(math warning...lots of statistics) that seems to blow away many (if not
all) assumptions about drive failures/quality/raid/etc.
It was presented at the same conference that the Google paper was. I'll
see if I can't dig up a URL to it.
