receiving, from a host, a request to change performance of each of a plurality of streams and a target performance ratio for each of the plurality of streams;
calculating, via a block calculator in a storage device, the performance of each of the plurality of streams based on the target performance ratio for each of the plurality of streams received from the host, and transmitting the calculated performance to the host;
upon receiving an approval on the calculated performance from the host, calculating, by the storage device, a number of write blocks to be allocated to each of the plurality of streams based on the calculated performance;
allocating, via a block allocator in the storage device, the calculated number of write blocks to each of the plurality of streams; and
storing, via a block pool, a block table in which write block information on write blocks currently allocated to each of the plurality of streams is recorded.
