Classification: CPC G | IPC G

Claim 0:
1. A storage device read-disturb-based read temperature map utilization system, comprising:
a storage device chassis;
a storage subsystem that is included in the storage device chassis;
a local read temperature utilization subsystem that is included in the storage device chassis and that is configured to:
determine, for a plurality of blocks in the storage subsystem, read disturb information;
identify, using the read disturb information, a subset of rows in at least one block in the storage subsystem that have a higher read temperature than the other rows in the at least one block in the storage subsystem;
generate, based on the identification of the subset of rows in the at least one block in the storage subsystem that have the higher read temperature than the other rows in the at least one block in the storage subsystem, a local logical storage element read temperature map that identifies a subset of logical storage elements associated with the storage subsystem that have a higher read temperature than the other logical storage elements associated with the storage subsystem; and
move data from at least one first block in the storage subsystem to at least one second block in the storage subsystem based on relative read temperatures identified in the local logical storage element read temperature map.
