Abstract:
Aspects of the present disclosure generally relate to storage devices and methods of operating the same. In one aspect, a storage device includes a disk, and a head configured to write data to and read data from the disk. The storage device also includes a controller configured to receive a read command in a host command queue, store the read command in a disk queue, and determine whether the host command queue is full of pending read commands, including the received read command. If the host command queue is full of pending read commands, the controller forces execution of one of the pending read commands.
