Claim 0:
1. A read-disturb-based read temperature information persistence system, comprising:
a host subsystem; and
at least one storage device coupled to the host subsystem, wherein each at least one storage device is configured to:
receive, from the host subsystem, a first instruction to write first data to a storage subsystem in that storage device;
write the first data to a first block in the storage subsystem in that storage device;
determine, based on first read disturb information associated with the first block in the storage subsystem in that storage device, at least one first read temperature for the first data stored in the first block in the storage subsystem in that storage device;
receive, from the host subsystem, a second instruction to write second data to the storage subsystem in that storage device, wherein the second data is an updated version of the first data;
identify the at least one first read temperature determined for the first data in the first block in the storage subsystem in that storage device; and
write the second data and a first read temperature indication of the at least one first read temperature to a second block in the storage subsystem in that storage device.
