ABSTRACT:
A storage device for storing data includes: an interface controller connectable to a host via a interface, the interface controller having an active state capable of transmitting data to the host and an inactive state having a lower power consumption than the active state; a medium for storing data; a head for read out data stored in the medium; and a processor for executing a process including receiving a command for reading out data stored in the medium from the host, determining timing when the data read out from the medium reaches the interface controller, and starting transition of the interface controller from the inactive state into the active state before the determined timing.
