Abstract

A storage system analyzes a logical block address range of data in a resolution of a defragmentation unit. The storage system determines whether a given defragmentation unit is fragmented above a threshold and performs a defragmentation operation accordingly. Additionally or alternatively, the storage system can receive a suggested logical block address read order from a host to improve performance.
