Abstract:
The present disclosure generally relates to data storage devices, such as solid state drives, and effective power management of the data storage device. The data storage device includes a controller, where the controller is configured to predict when a host device will send a command to enter a low power state, prepare the data storage device to enter the low power state, and receive a command to enter the low power state after the predicting and preparing. If the data storage device is idled for greater than a threshold value, then the data storage device prepares to transition to a low power state but will wait to enter the lower power state until receiving a request from a host device.
