Boosting Reads of Chunks of Data

Data may be read from a data storage device using host performance booster (HPB). An encoded HPB entry in a read command provides the PBA (Physical Block Address) as well as the run length. The LBA (Logical Block Address), PBA, and run length are placed in an HPB read buffer table. The HPB read buffer table is located in the host device. When the read command is received by the data storage device, the data storage device reads the LBA, transfer length, and HPB entry from the read command. The HPB entry contains the PBA for the LBA as well as the run length for the data to be read. For non-sequential reads, the HPB contains the LBA, transfer length, and reference to a write buffer table that is stored in the data storage device.
