SmartSaver: Turning Flash Drive Into a Disk Energy Saver for Mobile Computers

Overview In a mobile computer the hard disk consumes a considerable amount of energy. Existing dynamic power management policies usually take conservative approaches to save disk energy, and disk energy consumption remains a serious issue. Mean-while, the flash drive is becoming a must-have portable storage device for almost every laptop user on travel. This paper proposes to make another highly desired use of the flash drive - saving disk energy. This is achieved by using the flash drive as a standby buffer for caching and prefetching disk data. The design significantly extends disk idle times with careful and deliberate consideration of the particular characteristics of the flash drive.
