Sequential data optimized sub-regions in storage devices

A method, comprising:

• assigning, by a controller, a respective performance level to each storage region of a plurality of storage regions of a storage system, wherein each of the plurality of storage regions corresponds to a respective logical-to-physical (L2P) mapping table entry with a respective granularity, wherein the respective granularity indicates a respective mapping of a respective size of user data to a physical address entity;
• and
• selecting a storage region from the plurality of storage regions for an operation based at least partially on a performance level of the storage region, wherein the performance level is associated with a granularity of a L2P mapping table entry corresponding to the storage region.

A tangible non-transitory machine readable storage medium configured to store instructions, which when executed by a controller of a storage system, cause the controller to:

• assign a respective performance level to each storage region of a plurality of storage regions of the storage system, wherein each of the plurality of storage regions corresponds to a respective logical-to-physical (L2P) mapping table entry with a respective granularity, wherein the respective granularity indicates a respective mapping of a respective size of user data to a physical address entity;
• and
• select a storage region from the plurality of storage regions for an operation based at least partially on a performance level of the storage region, wherein the performance level is associated with a granularity of a L2P mapping table entry corresponding to the storage region.
