Description

technical field [0001] The invention relates to computer storage technology, in particular to a computer storage device control method, controller and storage device. Background technique [0002] In existing computer storage devices, whether it is an integrated disk electronics interface (IDE: Integrated Drive Electronics) hard disk or a small computer system interface (SCSI: Small Computer System Interface) hard disk, "Winchester" technology is used. In the "Winchester" technology, the disk body of the hard disk is composed of multiple disks, which are stacked together in a sealed box and driven by the spindle motor. When the hard disk is powered on, the spindle motor starts to work, and the disk rotates at a high speed; the disk does not stop rotating until the hard disk is powered off, or the host sends power management commands such as sleep. Uninterrupted high-speed operation still consumes energy when there is no data to read and write, resulting in waste of electric...
