Methods, systems, and computer readable media for advanced power management for serial advanced technology attachment (SATA)-based storage devices

Abstract

Methods, systems, and non-transitory computer readable media for advanced power management for serial advanced technology attachment (SATA)-based storage devices are disclosed. According to one aspect, the subject matter described herein includes a method for advanced power management of SATA-based storage devices. The method includes, at a SATA-based storage device having a controller, a non-volatile memory for storing data, and a communication interface for communicating with a host, receiving from the host a command to enter a quiescent mode. In response to receiving the command to enter a quiescent mode, the storage device enters a quiescent mode. The storage device receives from the host an indication that the storage device should enter a low power mode. In response to this indication, the storage device puts at least a portion of the non-volatile memory into a low power mode while maintaining at least a portion of the controller in normal power mode. The storage device optionally puts a physical layer interface of the storage device into a low power mode for additional power savings.
