Self-Learning Hard Disk Power Management for Mobile Devices
Overview A multitude of different hard disk power management algorithms exists - applied to real systems or proposed in the literature. Energy savings can only be achieved if the hard disk is idle for a minimum period of time. These algorithms try to predict the length of each idle interval at runtime and decide whether the disk should be switched to a low-power mode or not. This paper claims that there is no general-purpose policy that maximizes energy savings for every workload and present system services that dynamically switch between different, specialized power management algorithms.
