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.

Google has a very vast herd of machines with a

that they analyze failures and publish
the results to the web!
While the drives they are studying are definitely
not classic (all dating from 2001 or later),
those of us who host large quantities of classic
material may find the results of interest:

Side note: at one point I found it unbelievable
that Google was using consumer-grade hardware
to host their stuff. Since then, I've developed a
lot of respect for this approach!
