Abstract: Disclosed is a data managing method of a storage device which includes at least one nonvolatile memory device and a controller controlling the nonvolatile memory device. The data managing method includes receiving an input/output request and generating a section directing logical addresses based on the input/output request. The section is managed using section information, and the section information includes a start logical address corresponding to the input/output request, spatial locality information having the number of the directed logical addresses, and historical request information.
