Abstract
During operation of a data storage device, a controller of the data storage device may initiate read/write operations based on workloads provided by a host device. When initiating the read/write operations, power consumption and the data rate of the data storage device are generally high. Over time, the data rate corresponding to the workload decreases. Thus, the power consumption may be decreased to correspond with the decreased data rate. In order to maintain a high efficiency while decreasing an amount of power utilized, the controller may duty cycle the data storage device to operate between performance states to maintain a high data rate while decreasing power consumption.
