Hi all,
I bought a couple of second hand Dell EMC SAS SSDs. The Dell model No is V4-2S6F-100, but the underlying devices are Samsung (SMART output at bottom of post).
According to the SMART data both of them had ample life left with one having a "percentage endurance used count" of 8% and the other being at 0% (potentially used as a hot spare, based on the reads/writes). Over the weekend both bombed out on me, one on Friday, the other Sunday.
Both with this message in SMART:
According to information I found this means they ran out of endurance, the specific message being:
Given that these bombed out in exactly the same way in very short succession I suspect a firmware issue. However I couldn't dig anything up about these models having firmware issues and Dell EMC's support seems locked off.
The seller offered to replace them, however, if this is indeed a firmware issue then any replacements are likely to break in exactly the same way...
Does anyone here have any knowledge about these drives, and if, and where, I could potentially get updated firmware? I fully accept that I just might have been looking in the wrong places but haven't really found much more than a generic spec sheet on these...
Full SMART data of one of the SSDs (other is basically the same, just with a lot more use on it):

Given that they, supposedly, have between 92% and 100% endurance remaining that seems...odd?MEDIA IMPENDING FAILURE ENDURANCE LIMIT MET
