As previously mentioned, the OP is using a hardware raid system.  It is
impossible for ZFS to read "both sides of the mirror," which means it's pure
chance.  The hardware raid may fetch data from a bad disk one time, and
fetch good data from another disk the next time.  Or vice-versa.

You should always configure JBOD and allow ZFS to manage the raid.  Don't do
it in hardware, as the OP of this thread is soundly demonstrating the
reasons why.
