After 3.5 years in OEM hardware support WD was the least prone to
failure of them, next to hitachi then seagate. we settled on WD for
unifo0rmity easof product model numbers and price.
But we had a couple of designs that had a similar issue to yours multi
dis failures. only to find out that production of the case was
mounting fans in such a way it was baking half the drives so they were
dying due to thermals after about 6-10months.
altered one fan and life was great.
