Abstract
A method and apparatus to control an operating clock frequency of a hard disk drive. The method includes analyzing a command workload, and changing the operating clock frequency of the hard disk drive based on an analysis result. Alternatively, the method includes measuring a time taken to receive a predetermined number of write/read commands and controlling the operating clock frequency of the hard disk drive based on a result of a comparison of the measured time with at least one reference value. An operating clock frequency control block included in the hard disk drive executes the method.
