       Solid-state drive lifespan calculation formula: Due to the limited number of erase-write cycles of SSD flash memory, which is often criticized as a shortcoming affecting its lifespan, it is true that SSDs have a finite lifespan—though this is a characteristic shared by all hardware products. One complete erase-write cycle of the SSD's internal flash memory is called 1 P/E (Program/Erase cycle), and thus the lifespan of flash memory is measured in P/E units. The lifespan of 34nm flash memory chips is approximately 5,000 P/E cycles, while that of 25nm chips is about 3,000 P/E cycles. Does this seem even shorter? Theoretically, yes, but with advancements in SSD firmware algorithms, newer SSDs are capable of reducing unnecessary write operations. To give a concrete example: for a 120GB SSD, writing 120GB of data counts as one P/E cycle. For an average user, even if 50GB of data is written daily, it would take about 2 days to complete one P/E cycle, resulting in 180 P/E cycles per year. You can calculate how many years 3,000 P/E cycles would last—estimating a theoretical lifespan of over a decade. By that time, it's likely that the SSD would have already been replaced with some newer, more advanced technology.
