Abstract
A method for managing storage performance consistency, where the method determines a target throughput for writes to a memory sub-system, increases a tracking variable with a granularity based on the target throughput at fixed intervals, decreases the tracking variable based on writes of host data received from a host system to the memory sub-system, and adjusts a priority of host data writes to the memory sub-system relative to writes of reclaimed data from the memory sub-system in response to the tracking variable indicating a deviation from the target throughput.
