Wear leveling

Wear leveling is a technique used in flash memory storage, like USB drives and SSDs, to prolong their lifespan. Flash memory cells have a limited number of write/erase cycles before they wear out. Wear leveling ensures that data is spread evenly across all the memory cells rather than using the same ones repeatedly. This way, cells wear out at a similar rate, preventing some from failing prematurely. By distributing writes more evenly, wear leveling helps maintain the reliability and performance of storage devices over time.
