Abstract: A method is described, which includes receiving, by a memory subsystem controller from a host system, a host read memory command that references a set of logical block addresses associated with a set of transfer units of a memory device. The controller converts the set of logical block addresses to a set of physical block addresses for the set of transfer units; generates a set of device read memory commands based on the physical block addresses, wherein each device read memory command references at least one physical block address; and generates a first aggregated device read memory command based on a first device read memory command and a second read memory command in response to determining that the first device read memory command is associated with the second device read memory command. The controller thereafter transmits the first aggregated device read memory command to the memory device.

Abstract: Methods, systems, and devices for metadata indication are described herein. A method includes receiving, from a host system, a read command to retrieve information from a first block of a memory device, identifying a transfer unit associated with the first block indicated in the read command, identifying an indicator in metadata of the identified transfer unit indicating that at least one sector of the transfer unit has been altered based at least in part on identifying the transfer unit, validating data of the transfer unit stored in the memory device based at least in part on identifying the indicator in the metadata, and retrieving the information stored in the first block based at least in part on validating the data of the transfer unit.

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.
