Abstract
According to exemplary embodiments, a system, method, and computer program product are provided for BER-based wear leveling in a SSD. A block-level BER value for a block in the SSD is determined. An adjusted PE cycle count for the block is incremented or decremented based on the block-level BER value. Wear leveling is then performed in the SSD based on the adjusted PE cycle count.
