PURPOSE: A storage system for supporting a copy command and a move command and an operating method thereof are provided to perform a copy and a move by using the copy command and the move command distinguished from a read command and a write command without data migration of between a host and a storage device, thereby reducing a damage probability of data and improving power consumption and performance of the storage system. CONSTITUTION: A memory array includes storage spaces. A controller processes a command which is in a group of commands including a copy command, a read command, and a write command. The controller processes the copy command by renewing a mapping table of between logic and a physical address for enabling an original logic address and a goal logic address to instruct target data, when the copy command which is the target data indicating the original logic address for the goal logic address is received from the host. [Reference numerals] (AA) Host; (BB) Storage device; (CC) Controller; (DD) Memory array; (EE) Transmitting any one of reading, writing, copying and moving; (FF) Processing al copying or moving command internally by renewing a mapping table using an original logic address and a goal logic address in case of the copying or moving |
