A read disturb information determination system includes a storage device coupled to a global read temperature identification system. The storage device reads, from a first row in a storage subsystem in the storage device, data stored in bits that were previously identified as being susceptible to read disturb effects, and error correction information associated with the data. The storage device uses the error correction information to identify a number of the bits that store portions of the data with errors and, based on the number of bits that store portions of the data with errors, determines read disturb information for the first row in the storage subsystem in the storage device. The storage device then uses the read disturb information to generate a read temperature for a second row in the storage subsystem in the storage device, and provides the read temperature to the global read temperature identification system.
