Power consumption reduction of a mirrored RAID storage subsystems is disclosed, wherein data are mirrored to a secondary mirror disk system, the secondary mirror disk system alternates between an operational stage and a power-save stage, wherein data to be mirrored to the secondary mirror disk system is saved in a substantially always operational pre-stage storage if the secondary mirror disk system is in a power save stage and subsequently moved from the pre-stage storage to the secondary mirror disk system when the secondary mirror disk system is operational.
