A data storage device may include a nonvolatile memory apparatus and a controller. The controller may be configured to translate a logical address into a physical address when receiving a host command (such as a write command or a read command) including the logical address from a host device, to generate a pre-command including the physical address, to transmit the generated pre-command to the nonvolatile memory apparatus before completing one or more remaining operations of the operations used to process the host command, and to transmit a confirm command to the nonvolatile memory apparatus when the remaining operations are complete. The controller may perform the remaining operations and the transmission of the pre-command to the nonvolatile memory apparatus at the same time.
