[Nut-upsuser] estimated number of years to TBW math

My nvme drive has a warranty of 100TBW.
If I divide "Data Units Written:" by "Power On Hours:" I get the average 
written per hour.
If I divide 100 000 (100TB) that by 24 by 365 I get the number of years 
to get to 100TBW.
Right?
This is strictly the time to TBW, what things fail because of age?

> $ sudo smartctl -a /dev/nvme0n1 | grep 'Data Units Written:\|Power On Hours:'
