Ah, so the opposite of what I thought? Don't confuse the value from the
selftest log with the value from smartctl -a. There's also a value
Power_On_Hours in smartctl -a which I figured would be the hours it's on.
As I see now the RAW value of it is increasing, but certainly much faster as
that it could be counting the hours.
Ah, confirmed, I ran a second short test about one hour later and the value
in the log has increased by one, so it's indeed the power on time it has had
already. Thanks.

These are all at 253 (raw incidents = 0).
I understand that a drive that looks really well in SMART could still fail
next day, but at least there is no indication of that from this side.
