A storage system and method for user-defined data archiving are provided. In one embodiment, the method comprises: receiving a write command from a host; determining whether the storage system received an indicator from the host indicating that data of the write command is archive data; in response to determining that the storage system received the indicator, storing the data in the multi-level memory cells; and in response to determining that the storage system did not receive the indicator, storing the data in the single-level memory cells. Other embodiments are provided.

Storage system and method for user-defined data archiving

A storage system and method for caching a single mapping entry for a random read command are provided. In one embodiment, a storage system is provided comprising a memory and a controller. The controller is configured to determine whether a read command received from a host is a random read command, wherein the read command comprises a logical address; and in response to determining that the read command received from the host is a random read command, caching only an associated logical-to-physical address map entry from a logical-to-physical address map stored in the memory instead of caching a larger segment of the logical-to-physical address map that contains the entry and other entries. Other embodiments are provided.
