Energy efficient design for disk devices has become a very important issue, because ever increasing need for data storage systems significantly increases the power budget in the disk array. Most research on power management in disk devices focuses on the traditional way of stopping disk rotation. This paper proposes a new approach in which the energy consumption can be reduced without stopping the disk rotation. The proposed Multiple Idle States (MIS) model modulates the disk RPM to optimize the energy consumption during idle periods.
