A data storage device which exchanges multi-stream data with a host includes a nonvolatile memory device; a buffer memory configured to temporarily store data to be stored in the nonvolatile memory device or data read from the nonvolatile memory device; and a storage controller configured to receive from the host an access command for accessing segments of the multi-stream data, the accessing including reading the segments of the multi-stream data from or writing the segments of the multi-stream data to the nonvolatile memory device, wherein the storage controller is configured to store the access-requested segments in the buffer memory, the access-requested segments being the segments of data for which access is requested in the access command, the multi-stream data including a plurality of data streams that correspond respectively to a plurality of multi-stream indexes, the first multi-stream index being one of a plurality of multi-stream indexes.

Storage device and data processing method thereof

A method of managing power of the storage device including a first processing core for controlling a first function block and a second processing core for controlling a second function block includes: analyzing a pattern of commands received from the outside; selecting an operation mode of the storage device based on the analyzed pattern; and managing the electric power of the storage device by using the first processing core if the selected operation mode is a first mode, and separately managing electric powers of the first and second function blocks by using the first and second processing cores, respectively, if the selected operation mode is a second mode.

Power management of a storage device including multiple processing cores

A method of manipulating data includes receiving a data manipulation command for corresponding data, which corresponds to a first logical block address, to a second logical block address. The method further includes mapping the second logical block address to a physical block address, which is mapped to the first logical block address, in response to the data manipulation command. A system for manipulating data includes a host and a flash translation layer. The host transmits a data manipulation command for corresponding data, which corresponds to a first logical block address, to a second logical block address. The flash translation layer maps the second logical block address to a physical block address, which is mapped to the first logical block address, in response to the data manipulation command.
