Found via InsideHPC (quoting EnterpriseStorageForum.com):
Intel found that if a user sets up a BIOS password on the SSD, then disables or changes the password, the contents of the drive become corrupted and irretrievably lost.
Probably not an issue for HPC storage systems, more an issue for desktop ones I guess.
I’m not surprised. I don’t have much faith in the multi layer devices yet.. If people are serious, I’d stick to the hella expensive SLC.
