Well, given I always use RAID-6, it shouldn't matter; a failed drive
shouldn't alter the array behaviour significantly, as it simply falls
back to sort-of RAID-5 (any bad block read or write should be corrected
on the fly).

It seems like explicitly disabling individual disk drives write-back
cache somewhat mitigates the effect.
