I cant remember how old my 980 pro is or where I bought it, cant find the reciept but I never had any isues updating the firmware when used in main M.2 slot OS drive. I just checked & Im on 5B2QGXA7.
Actually I did just find the box however & the production date is 2/14/2021. Never had any issues with the drive but I may need to rethink my loyalty to Samsung & research TBW/Endurance on current NVME drives & manufacturers
EDIT: I just noticed that my 2 year old 980 pro 1tb has less writes on it than my less than 2 month old 990 pro 1tb! Whats up with that? Assuming SMART is accurate.
Both drives were used as OS drives with hibernate turned off & similar windows settings. Samsung claims both drives are 600 TBW, smh
