Abstract: A method for executing a hard disk operation command, a hard disk, and a storage medium. After an operation command is received, a target LUN in an idle state is determined; a target physical block that is to be accessed when the operation command is executed is determined from the target LUN; the operation command is stored in a processing waiting queue corresponding to a flash memory chip to which the target physical block belongs; and a working state of the target LUN is changed to a non-idle state when a quantity of operation commands that wait to be processed in a processing waiting queue respectively corresponding to each flash memory chip in the target LUN is greater than a preset threshold.
