System and methods are provided for data storage management in a memory device. A first logical block corresponding to a plurality of first physical blocks of a memory device is selected. A source physical block within the first physical blocks is determined, the source physical block including less valid data than one or more second physical blocks within the first physical blocks. A target physical block of the memory device is obtained. The valid data in the source physical block is copied to the target physical block. The source physical block is released for storing new data.

Systems and methods for data storage management

Systems and techniques relating to input/output (I/O) command aggregation include, according to at least one implementation, a method including receiving a first command from a device driver through interface hardware for accessing a storage device; identifying the received command as an aggregation command having a tag corresponding to consolidated command information; communicating a transfer ready notification to the device driver; receiving the consolidated command information from the device driver, wherein the consolidated command information includes memory addresses and data transfer counts for a defined quantity of aggregated I/O commands or for aggregated I/O commands that are received within a defined period of time; storing the consolidated command information in memory; receiving a second command including the tag corresponding to the consolidated command information; and processing the second command with respect to the storage device based on the memory addresses and the data transfer counts in the consolidated command information.

Input/output (I/O) command aggregation

The present disclosure includes systems and techniques relating to input/output (I/O) command aggregation for Small Computer System Interface (SCSI) enabled devices. In some implementations, a method can comprise receiving a first command for a target device, wherein the first command includes a first memory address and a first data transfer count; receiving a second command for the target device, wherein the second command includes a second memory address and a second data transfer count, and wherein the first and second commands are entirely read commands or entirely write commands; aggregating the first and second memory addresses and the first and second data transfer counts into consolidated command information; generating a packet command that includes a packet tag and a data size corresponding to the consolidated command information; communicating the packet command to the target device; in response to receiving a transfer ready notification from the target device, communicating the consolidated command information to the target device; and communicating additional information to the target device.
