Summary:A storage device with improved security performance is provided. The storage device comprises a first non-volatile memory storing a firmware image, a second non-volatile memory storing an emergency image, and a storage controller controlling the first and second non-volatile memories, wherein the storage controller checks an integrity of the firmware image received from the first non-volatile memory, loads and executes the emergency image from the second non-volatile memory when the integrity check of the firmware image fails, receives a recover image from an external device based on the emergency image, and provides the recover image to the first non-volatile memory.
