Abstract:
Systems and techniques for control of storage device power states are described herein. In some embodiments, a control system for a storage device of a computing device may include receiver logic to receive a proximity signal indicative of a distance of a user from a proximity sensor, transition logic to determine that the proximity signal satisfies out-of-proximity criteria and generate an out-transition signal based at least in part on the determination that the proximity signal satisfies the out-of-proximity criteria, and state-change logic to cause a change in a power state of the storage device from a first power state to a second power state, in response to the out-transition signal, wherein the storage device consumes less power in the second power state than in the first power state. Other embodiments may be described and/or claimed.
Abstract:
A controller maintains exposed and unexposed locations of a first storage device and a second storage device. In response to receiving a request a perform a write operation to write data in locations that span the first storage device and the second storage device, the controller atomically writes an entirety of the data in the unexposed locations of the first storage device.
