Abstract
A method and system to provide a command queue re-ordering method that can make the power save and reduction in acoustic noise. The command queue re-ordering method involves calculating the value of an evaluation function, Ev=A×T+(1−A)×Fun(L) (A is any number from 0 to 1, T is a latency required to execute a write command and/or read command, and Fun(L) is an evaluation function with a seek distance L) for the write command and/or read command, and selecting the write command and/or read command having the minimum value as a next command to be execute.
