Abstract
Aspects of the disclosure provide a method and an apparatus that perform a background media scan (BGMS) with improved efficiency. In particular, the disclosed BGMS processes can monitor data retention performance of a large capacity solid state drive (SSD) without significantly increasing scanning overhead by scanning only some sample pages of a memory block.
