install smartmontools.
execute code in terminal smartctl -x /dev/sda
(it is /dev/sda if ssd is your primary drive , sdb if its secondary drive)
you can see completed life of your drive from “percentage used endurance indicator” attribute (it will %100 when drive is near to death)
Seems to be ssd dashboard have pretty much issue with device health counters.
i have similiar issue , it cant report health very well. but smartctl works pretty good
