Which is weird because the only microSD card I've ever had fail on me locked itself into write-protect mode, allowing me to get my data. I wonder why SSDs don't do the same.
They're supposed to, and I've heard anecdotes that they sometimes do, but it seems like many of the failures I've experienced were firmware failures (in some cases, upgrading firmware on remaining drives seemed to result in lower failure rates anyway). Firmware failures have no rules; spinner drives sometimes have them too, and they might disappear from the bus as well, although usually those will "just" disappear after a reboot, not in the middle of a request.
