    Abstract: A storage device includes: a buffer to receive first data and second data from outside, and store the first data and the second data on a first page; a non-volatile memory to store the first data and the second data in a first block; and a controller to perform a program operation that programs the first and second data in free blocks different from each other through a garbage collection. The first data may include a first stream class number identifying characteristics of the first data, and the second data may include a second stream class number identifying characteristics of the second data and is different from the first stream class number. The controller may transmit information of the program operation to the outside before performing the program operation. The controller may perform the program operation when receiving a program execution permission command from the outside.
