Depends upon the device. SSDs will give you a warning via SMART; they will
begin to retire blocks and swap in reserved blocks. Simpler devices
such as memory
cards and USB sticks will simply die. I use SSDs in
mission-critical applications,
so that I have at least a fighting chance of replacing them before
there's an outage.
