Most "SLC" and "MLC" that's sold is actually TLC/QLC hardware that's only using a subset of the voltage levels available. It ends up being significantly cheaper due to the economies of scale in manufacturing.
- jsheard 2y agoYep, if you ever come accross the term "pSLC" (Pseudo-SLC) that means the underlying hardware is capable of running in MLC/TLC/QLC mode, but the controller firmware has been configured to only use the lowest and highest voltage state in each cell. Some SSD controllers will also reassign regions of flash to different modes on the fly, the drives unused capacity can be used internally as a very fast pSLC write cache, and then as the drive fills up those cells incrementally get switched over to the native TLC/QLC mode.
- Iulioh 2y agoDoes this mean that in some cases damaged QCL "sectors" could be still used as a SCL?
