Early transition of data storage device to low power mode

The invention relates to an early transition of a data storage device to a low power mode. The present disclosure generally relates to data storage devices, such as solid state drives, and efficient power management of the data storage devices. The data storage device includes a controller configured to predict when a host device is to send a command to enter a low power state, prepare for the data storage device to enter the low power state, and receive a command to enter the low power state after the prediction and the preparation. If the data storage device is idle beyond a threshold, the data storage device prepares to transition to a low power state, but will wait to enter the low power state until a request is received from the host device. 本发明题为"数据存储设备提早转变到低功率模式"。本公开整体上涉及数据存储设备(诸如固态驱动器)，以及该数据存储设备的有效功率管理。该数据存储设备包括控制器，其中该控制器被配置成预测主机设备何时将发送进入低功率状态的命令，准备使该数据存储设备进入该低功率状态，以及在该预测和该准备之后接收进入该低功率状态的命令。如果该数据存储设备空闲了超过阈值，则该数据存储设备准备转变到低功率状态，但是将等待进入该低功率状态，直到从主机设备接收到请求。
