Summary:Priority-based garbage collection utilizes attributes of data stored in the non-volatile memory array in order to improve efficiency of garbage collection and of the overall data storage system. A set of low priority data can be selectively evicted from a non-volatile memory array. This can, for example, reduce write amplification associated with garbage collection. Another set of low priority data can be regrouped or consolidated in a different region of the non-volatile memory array. In addition, flushing of data can be performed in order to enhance or optimize garbage collection. Performance and endurance can thereby be improved.
