If your running that big of a shop, I would call your channel partner/support group and bitch until they figure out whats failing. The usual expected failure modes for SSD's should be that they go into read only mode. If that isn't happening its either a firmware bug (probably) or a controller/vr failure which could be a process/heat/etc type of failure.
Particularly for "enterprise" equipment the expectations isn't that it fails, but that the failures are more graceful and understood.
So complain... that is why your paying the "enterprise" tax.
This was in managed hosting, we'd open a ticket and get teh SSDs replaced quickly, which was good enough for us. For the most part, the failure rate was about 10% of the rate of the hard drives, and concentrated in the systems with many disks, which were setup to handle disk failures, so it wasn't a big big deal.
Although we did get a couple of bad batches on our single disk systems, almost all of those failed within 2 weeks of install and we had the rest replaced.
I also suspect firmware bugs, but it wasn't convenient to upgrade them, so who knows. I did have to upgrade some of the same disks on single disk systems with low usage; the disks would sometimes timeout for no reason and confuse some of our OSes. The upgrade procedure was more or less PXE boot the manufacturer upgrade utility and hope it worked with whatever disk controller was there (eta: 5 minutes) or let the hoster firmware upgrade script run and hope it upgraded the ssd firmware and didn't mess anything else up (eta: 40 minutes per run, probably run it twice).
Particularly for "enterprise" equipment the expectations isn't that it fails, but that the failures are more graceful and understood.
