Abstract
A storage system and method for enabling host-driven regional performance in memory are provided. In one embodiment, a method is provided comprising receiving a directive from a host device as to a preferred logical region of a non-volatile memory in a storage system; and based on the directive, modifying a caching policy specifying which pages of a logical-to-physical address map stored in the non-volatile memory are to be cached in a volatile memory of the storage system. Other embodiments are provided, such as modifying a garbage collection policy of the storage system based on information from the host device regarding a preferred logical region of the memory.
