SSDs have limited program/erase or P/E cycles. In this video I discuss the life expectancy of SLC, eMLC, MLC and TLC drives, as well as covering wear levelling, over provisioning, and TBW, PWB and DWPD endurance ratings. Note that the data presented in this video was obtained from a great many sources, including all major SSD manufacturers, and was up-to-date as of 25 March 2017. Note also that the second SSD listed in the table of client SSDs at c.6:41 is a Samsung 850 Pro, not a Sandisk 850 Pro (which does not exist).
