Data storage devices with an open protocol may be limited in terms of input / output operations per second (IOPS) due to the time taken to stop the transmission cleanup activity. A data storage device is disclosed that may increase IOPS by using command length estimation logic that stores / memorizes a command length of a previous write / read command and limits a next open read / write command to a predicted / memorized length. This increases IOPS by eliminating the need to perform a stop transmission cleaning activity.
