Abstract

A storage system, host, and method for storage system calibration are provided. In one embodiment, a storage system is provided comprising a memory and a controller. The controller is configured to: determine a pattern of host writes to the memory; determine whether the pattern of host writes matches a granularity of a logical-to-physical address map used by the storage system; and in response to determining that the pattern of host writes does not match the granularity of the logical-to-physical address map used by the storage system, change the granularity of the logical-to-physical address map used by the storage system. In another embodiment, the storage system calibration is done by host directive. Other embodiments are provided.
