A data storage device includes a storage including a buffer zone and a data zone and a controller for exchanging data with the storage by allocating at least one zone namespace (ZNS) in the data zone, a ZNS being a data storage region that is physically and logically divided and allocated to each of application programs driven in a host. The controller opens one or more sub buffer zones in the buffer zone, divides write data from the host into one or more segments respectively corresponding to sizes of the one or more sub buffer zones, buffers each of the one or more segments in a corresponding one of the one or more sub buffer zones, opens a ZNS corresponding to a length of the write data in the data zone, and migrates the one or more segments buffered in the sub buffer zones to the opened ZNS.

Data storage device and operating method thereof

A memory system includes a storage medium having a plurality of memory regions. A controller is configured to allocate each of a plurality of open memory regions among the memory regions to one or more levels and store, in response to a write request received from a host device that includes data and a level of the data, the data in an open memory region allocated to the level. A level may be a level of a file in a predetermined unit in which the data is included, such as in a log-structured merge (LSM) tree structure.

Memory system for storing data of log-structured merge tree structure and data processing system including the same

A data storage device and a storage system including the same are disclosed. The data storage device includes a nonvolatile memory device configured to store user data and metadata including data type identification information matched with the user data, and a controller to control the nonvolatile memory device to be switched to a cold data storage device for storing cold data only when a number of program-erase (PE) cycles of the nonvolatile memory device is equal to or larger than a reference value.

Data storage device, storage system using the same, and method of operating the same
