zfs pool ssd cache drive dropping off

[cruxpot]

When I first put it in, it was working fine but I logged in one day and
that was the state it was in. It dropped off after 7 days. After a recent
reboot, it dropped off an hour later according to the timestamps. Are there
some diagnostic commands on FreeBSD to help me determine if the SSD is
going failing or not? I'm wondering if ZFS killed it. I simply added to a
raid-z with "zpool add <pool> cache /dev/ada4" command. I can try a
different SATA cable and port but it is probably a small chance that is the
problem because this seems to be an intermittent issue.
