Abstract:
A defragmentation method of a user device which includes a host and a nonvolatile storage device includes: determining whether fragments of a first file stored at the nonvolatile storage device are in a same logical address zone; and executing defragmentation on the fragments of the first file if the fragments of the first file are in different logical address zones by moving the fragments of the first file to a logical address space corresponding to at least one of the different logical address zones.
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.
