Abstract

An operating method for a data storage device includes providing a nonvolatile memory device including a plurality of pages; segmenting an address map which maps a logical address provided from a host device and a physical address of the nonvolatile memory device, by a plurality of address map segments according to a segment size that is set depending on a quality of service time allowed to process a request of the host device and an unprocessed workload; and flushing at least one of the address map segments in the nonvolatile memory device after processing the unprocessed workload.
