"It's common sense" = the logical fallacy of hand waving. Show me
statistical evidence. I have had lightly loaded drives die in under 2
years and heavily loaded ones last 10 years. I have replaced failed
drives in a raid and the other drives with essentially the same wear on
them lasted for years without another failure. There does not appear to
be a strong correlation usage and drive failure. Certainly not one that
is so strong that you can claim with a straight face that after the
first failure, a second one can be expected within X IOPS, and the IOPS
needed to rebuild the array are a significant fraction of X.
