Abstract: An electronic system includes: a host configured to run a plurality of virtual machines; and a storage device including a plurality of memory regions and configured to divide data from the host into a plurality of streams and separately store the plurality of streams in the plurality of memory regions. The storage device assigns a first stream identifier (ID) to a first virtual machine, among the plurality of virtual machines, in response to a check-in snapshot command of the first virtual machine, and stores data in a first memory region corresponding to the first stream ID, among the plurality of memory regions, in response to a write command of the first virtual machine. The storage device stores snapshot management information including the logical addresses of the data in response to a check-out snapshot command from the first virtual machine and releases the assignment of the first stream ID.
