That is flash memory cells that can only be programmed and erased a limited number of times. This is referred to as P/E cycles. This can vary from 1000 to 100,000.Then we have the TBW. Terabytes written is the total amount of data that can be written to an SSD before it is likely to fail. eg for Samsung 860 EVO SSD: 150 TBW for 250 GB model, 300 TBW for 500 GB model, 600 TBW for 1 TB model, 1,200 TBW for 2 TB model and 2,400 TBW for 4 TB model.Note:  The warranty is 5 years or TBW, whichever comes first.Then the standard MTBF — (mean time between failures) is a measure of how reliable a hardware product or component is over its expected lifetime.For a SSD maybe million hours. This is only a statistical indicator and does NOT mean that it will work for a million hours.Then of course we have the SSD type.SLC (Single Level Cell), MLC (Multi-Level Cell) — two bits per cell, TLC (Triple Level Cell) — three bits per cell, QLC (Quad Level Cell) — four bits per cell.A SLC SSD would technically be the most reliable SSD as it can endure more writes, while a QLC is the least reliable.So it's a bit complicated than what you see on the surface.</blockquote>
