SSD endurance is how many program/erase cycles can be applied to a block before it becomes unreliable. A common term for measuring endurance of a drive is TeraBytes Written or TBW. 6PB write endurance being too low for OPs needs. Unlike hard drives, flash memory has one major weakness: manufacturers only guarantee you can write to each cell a certain number of times. Please note Jul 10, 2019 · Hi, we have the following problem. Oct 11, 2023 · SSD endurance is an essential consideration for users who frequently write large amounts of data or perform demanding tasks that involve frequent write operations. Reading a flash memory cell involves checking its charge level, so to retain stored data, the electron charge must remain stable over time. One key metric for SSD endurance is P/E cycles. Here’s how you can estimate how long the SSD will last: TBW. So, for example, if an SSD has 350 TBW, you can write a total of 350TB to it before you may have to replace it. Two key metrics measure this endurance: Sep 26, 2018 · SSD endurance is the total amount of data that an SSD is guaranteed to be able to write under warranty, often specified in “TBW” or “DWPD” (which we’ll discuss a little later).
