ABSTRACT:
A system and method for optimizing power consumption by a disk drive unit. The system and method monitor and analyze historical use data and calculate a predicted inactivity duration. The predicted inactivity duration is used to power-down the rotational speed of the drive to the first of one or more intermediate rotational speeds. Continued inactivity will result in further speed reduction until the drive is ultimately powered off. The drive increases rotational speed on demand.
