My Macbook M1 which I use extensively since 2021:

Data Units Read : 1267900331 (649.16 TB)

Data Units Written : 904681650 (463.20 TB)

power_cycles : 667

power_on_hours : 9611

and yet it's still only:

available_spare : 100%

available_spare_threshold : 99%

percentage_used : 16%

I don't expect it to fail anytime soon.
