Abstract: A data storage device includes a nonvolatile memory device including a plurality of memory blocks, and a storage controller that manages a plurality of streams in the plurality of memory blocks. The storage controller receives, from a host, a write command that requests a write operation and a data block including write data and an application tag appended to the write data, and selects one of the plurality of streams based on the application tag included in the data block. The storage controller writes the write data included in the data block into the selected one of the plurality of streams.
