I do very simple mental calculation. Preface .There was a test about memory endurance of the SSD, where they were actually written to death and precise number of data was measured (not estimated). That was in the age of Sata SSDs, so not super recent, but memory cells were actually more durable in those times, due to bigger tech process and lower number of bits per cell. In the end 256 Gb drives failed after writing 1-3 petabytes of data. So when I'm buying 1 Tb modern mid range drive, I expect about 4 Pb of writes on it, but I halve that number because of the worse tech process and more levels per cell, and additionally halve again due to by personal build (SFF PC) operating at higher temperatures, not good for the lifespan. None of my drives have reached even 10% of 1 Pb yet, so I don't care too much about memory lifespan.
