마모 평준화
마모 평준화(Wear Leveling, WL) 기술은 SSD의 모든 낸드 플래시 블록이 균등하게 사용되어 불량 블록이 과도하게 발생하거나 특정 블록에만 데이터 쓰기 또는 삭제가 반복되어 조기에 손상되는 것을 막기 위한 기술입니다.
WL을 사용하면 Soc 컨트롤러가 WL 알고리즘을 통해 각 블록의 남은 P/E 횟수를 계산하여 삭제 빈도가 낮은 블록에 새로운 데이터를 기록합니다. 컨트롤러가 각 블록의 P/E 빈도를 고르게 제어하기 때문에 SSD는 특정 블록의 과도한 P/E로 인한 조기 마모 및 손상을 피할 수 있게 됩니다.
