Abstract: A method of managing a data storage device including a memory controller and a memory device includes: calculating a first sequential and consecutive write cost (SCWC) according to a garbage collection (GC) write operation policy, a second SCWC according to a slack space recycling (SSR) write operation policy and a third SCWC according to an in-place updating (IPU) write operation policy respectively, in response to a write request in the memory controller; determining a write operation policy which has a minimum cost of the first through third SCWCs; and writing data in a selected segment in the memory device according to the determined write operation policy.
