Abstract:
According to one embodiment, a power management module of a storage device executes a process of stopping rotation of a disk storage medium by selectively using one of a first mode of stopping the rotation of the disk storage medium on condition that a media access command is not received during a predetermined time from last reception of a media access command, and a second mode of stopping the rotation of the disk storage medium on condition that a media access command which causes access to the disk storage medium is not received during a predetermined time from last reception of a media access command which causes access to the disk storage medium. In addition, the power management module executes a process of starting the rotation of the disk storage medium by selectively using one of a third mode and a fourth mode.
