"WitrynaP/E cycle: A solid-state-storage program-erase cycle is a sequence of events in which data is written to solid-state NAND flash memory cell (such as the type found in a so-called flash or thumb drive), then erased, and then rewritten. Program-erase (PE) cycles can serve as a criterion for quantifying the endurance of a flash storage device. " - Nand flash write cycles
