About 100 database servers with over 1000 drives spinning 24/7. Also probably significant, management-set policy is to replace machines after four years, and we don't always hit that. I haven't tried to run numbers on it, but the pattern sure seems to match published reports that we have some initial failures within the first few months when a set of machines go in, it settles down for about three years, then the failure rate starts to edge inexorably upward. >> As a place to put "one more copy" it might make sense, as long as >> it had strong encryption. > I didn't expand but that's what I meant.
