Abstract
A power controller includes a power detector detecting supply of first power given a predetermined power level and second power given a power level lower than the first power, a supply power switch supplying a storage with the first power when the power detector detects supply of the first power and supplying the storage with the second power switching from the first power to the second power when the power detector detects supply of the second power only, and a data transfer rate controller setting a data transfer rate between a predetermined data transfer source/destination and the storage to a second data transfer rate lower than a first data transfer rate coupled with the supply of the first power when supply of the second power only is detected, to reduce power consumption of the storage in comparison to power consumed by a data transfer at the first data transfer rate.
