A data storage device with a non-volatile memory on which a garbage collection operation is segmented to be accomplished at separate time intervals. Host commands are inserted to be executed between the separate time intervals. A data swap stage or/and an F2H table update stage or/and an H2F table update stage for a garbage collection operation may be segmented to be performed at separate time intervals.

Data storage device and operating method thereof, wherein mapping table for valid data of source block that has not been copied to destination block has a higher priority than mapping information collected by reverse scanning from end of the destination block

A data storage device with a non-volatile memory on which a garbage collection operation is segmented to be accomplished at separate time intervals.
