Reading this makes me wonder if you checked your environment for
other influences.  there must be some reason for an exceptional high
number of failures.

I remeber we also had a nighmare of disk errors in the rack in the
2nd floor of our building - which disappeared after moving the rack
into the basement.  I can't prove it, but I blame it on vibrations.
We have a heavy traffic train line less than 50 meters away, and
disks (classic, magnetic ones) definitely do not like vibrations -
see [1].  Maybe you have other influences you did not check for yet?
