See full text

A computer processor determines an over-provisioning ratio and a host write pattern. The computer processor determines a write amplification target based on the host write pattern and the over-provisioning ratio. The computer processor determines a staleness threshold, wherein the staleness threshold corresponds to a ratio of valid pages of a block to total pages of the block. The computer processor erases a first block having a staleness which exceeds the staleness threshold.
