IIRC from heterogeneous disks in an array I had once, I was getting 10*
the number of errors on one pair of disks from the other pair.  It
turned out that seagate was reporting uncorrectable errors and WD was
reporting all errors -- the seagate had an extra field where it reported
the raw error rate.

If you are gonna script a "not okay" heuristic, be careful not to
overgeneralize from one vendor to the next.
