Speed control systems and methods for decreasing power consumption in rotating storage devices
Abstract:
A system for controlling a rotational speed of a platter in a storage device. The system includes a mode selection module configured to select a mode operation for the storage device, in which the mode of operation includes at least i) a read/write mode in which data is to be read from or written to the platter, ii) a standby mode during in which data is not to be read from or written to the platter, or iii) a shutdown mode. The system further includes a speed control module configured to control the rotational speed of the platter based on the selected mode of operation for the storage device.
