As sure as possible, anyway.  I'm thinking of Google's analysis of many
years' worth of failure data (or was it the other disk failure paper
from that conference a couple months back?) that found one of the
highest correlations was among same-lot drives, such as a casual raid
pair very likely will be.  Odds of a failure were much higher for soe
time following a failure of such a sibling drive.  I know I have
mirrors like that; the newest & biggest has different vendor drives
only by good fortune...
