Describe the power consumption statistics of the hard disks.

- These days power consumption of electrical devices has become a prime importance as portability and performance greatly depends on a devices consumption.

- Power consumption of a hard disk directly affects: Drive age, disk failure rates, temperatures etc.

- Smaller drives consume less energy as compared to large drives. The disks consume maximum energy during starting up, also known as spin up.

- Spin up and spin down is directly controlled by the SCSI controller on such drives.
