Also note that you may be able to get more detailed information
on the problem using smartctl:
pkg_radd smartmontools
smartctl -d sat -a /dev/daXXX (where daXXX is the correct device for
the SSD).
In particular look at the wear indicator, which is typically attribute 233,
and available reserved space, which is typically attribute 232 (but it
depends on the SSD).
