I'm not aware of a kill switch. What I think is being referred to is the "endurance" of an SSD. SSD's specs should tell you the "endurance" of the drive, expressed in the amount of data that can be written. Usually in TiB written or PiB written. For example for my Samsung SSD 980 PRO 2TB the endurance is 1,200TB written. See Warranty on page 3 for https://download.semiconductor.samsung.com/resources/data-sheet/Samsung-NVMe-SSD-980-PRO-Data-Sheet_Rev.2.1_230509_10129505081019.pdf As a rule of thumb, if the spec does not list the endurance of the SSD then I would not trust the drive to last.
