Claim 5:
6. A storage device, comprising a Central Processing Unit (CPU), a Serial Attached SCSI (SAS) port control chip, and
a hard disk drive system, wherein the hard disk drive system comprises two or more hard disk drives, and the SAS port control chip is configured to:
latch the initialization states of all the hard disk drives after all hard disk drives are powered on;
divide all hard disk drives into two or more hard drive groups, each hard drive group comprising more than one hard disk drive; and
sequentially performing link initialization negotiation on each hard drive group by using a port protocol; and in an OOB negotiation process of the link initialization negotiation, by setting the state of an SCSI application layer power state machine, controlling a motor of each hard disk drive in the hard drive group to enter a spinning state.
