Not as slim as manufacturers want to make you believe. RAID drives
tend to be purchased at the same time, so they are often from the same
batch. They are then subjected to exactly the same load in exactly the
same environment. Is it any surprise that they fail at the same time?

Especially if they are kept running for a very long time and then shut
down by a power failure.
