A storage device comprising: a nonvolatile memory device including a first area, a second area, and a third area; and a controller configured to receive a write command and first data from an external host device, to write the first data in the first area or the second area rather than the third area, when the first data are associated with a turbo write, and to write the first data in the first area, the second area, or the third area based on a normal write policy when the first data are associated with a normal write, wherein the controller is further configured to receive a read command from the external host device, to read second data from one of the first area, the second area, and the third area based on the read command, and to output the second data to the external host device, wherein the controller is further configured to move the second data in response to move information of the read command when the read command is received together with the move information, and wherein the second data are moved by writing the second data into another one of the first area, the second area and the third area and invalidating the second data at the one of the first area, the second area and the third area, wherein the move information includes information of a destination area indicating the another one of the first area, the second area, and the third area, characterized in that the move information further includes force level information including whether to evict partial data of third data stored in the destination area or whether to leave partial data of the second data without moving partial data when a capacity of the second data is greater than a free capacity of the destination area. a nonvolatile memory device including a first area, a second area, and a third area; and a controller configured to receive a write command and first data from an external host device, to write the first data in the first area or the second area rather than the third area, when the first data are associated with a turbo write, and to write the first data in the first area, the second area, or the third area based on a normal write policy when the first data are associated with a normal write, wherein the controller is further configured to receive a read command from the external host device, to read second data from one of the first area, the second area, and the third area based on the read command, and to output the second data to the external host device, wherein the controller is further configured to move the second data in response to move information of the read command when the read command is received together with the move information, and wherein the second data are moved by writing the second data into another one of the first area, the second area and the third area and invalidating the second data at the one of the first area, the second area and the third area, wherein the move information includes information of a destination area indicating the another one of the first area, the second area, and the third area, characterized in that the move information further includes force level information including whether to evict partial data of third data stored in the destination area or whether to leave partial data of the second data without moving partial data when a capacity of the second data is greater than a free capacity of the destination area.
