Original Abstract Submitted
A method for performing disk access operations in a disk drive includes: storing commands to perform disk access operations in a command queue for the disk drive; determining a first total cost for performing a first command stored in the command queue, wherein the first total cost is based on at least a first energy cost associated with starting execution of the first command; determining a second total cost for performing a second command stored in the command queue, wherein the second total cost is based on at least a second energy cost for the second command; and in response to determining that the first total cost is less than the second total cost, selecting the first command to be the next command stored in the command queue that is to be performed by the disk drive.
