No what I was describing is if the SSD fails completely and as far as Linux is concerned it's just gone. I've seen a few harddisks fail like that just recently (heatwave over here in AU) where the computer seems to be working okay then things just freeze up, and after a reboot there is no harddisk anymore. I haven't used SSD's enough to have seen something like that yet, but if it's a controller failure then it's possible. I was just wondering how data integrity would fare in such a case. I guess it's the same as if there was a power failure and then you removed the SSD before booting up again, except that I believe bcache can bypass the cache for certain types of streaming writes so there is the potential for things to get out of sync, maybe?
