We see a lot of SSD errors that turn out to be problems with RAID controllers. The lost drive rate dropped quite a bit when we started using OS-level RAID functionality rather than whatever the heck is in the firmware of Promise / LSI / Adaptec / etc. cards, and we were able to return a bunch of drives to service after we started using those cards in a simple pass through mode. Raise your hand if you've lost data that was RAIDed eight ways to Sunday because of a RAID controller failure that turned out to be unrecoverable because of crappy decisions in the firmware, or rebuild times equal to the number of days it took to order, rack and configure a competitor's product.
