Ssd Controller Here

Computers think in logical addresses, but flash memory works in physical ones. The controller maps these together, essentially keeping a master index of where every single piece of data is stored on the chips.

Flash memory has a limited lifespan—every time you write or erase data, the cells wear down slightly. To prevent one part of the drive from dying early, the controller uses wear leveling algorithms to spread data out evenly across all available cells. SSD CONTROLLER
