see anything wrong?

When working properly, the drive dies when it uses up all the
"available_spare" capacity. This report is similar to what I
see, but I only have 3 nvme drives.

There are failure modes other than something that
degrades over time and can be monitored.

I have 1,812 for num_err_log_entries on a new drive
(291 power_on_hours), so I suspect many of
these log entries come when a drive is first
installed.
