description Provided are a storage device and a driving method therefor. The storage device comprises: a non-volatile memory to which data is written in a mapping size unit; and a storage controller that provides a command to the non-volatile memory, wherein the storage controller comprises a host interface that receives a write command instructing to write the first data of a first size smaller than that of a mapping size unit to a first address from a host, and a partial write reader that provides a read command for reading the second data stored in the non-volatile memory that is addressed based on the first address to the non-volatile memory before the first data is received through the host interface. Therefore, the present invention is capable of improving an operating performance. 스토리지 장치 및 그 구동 방법이 제공된다. 스토리지 장치는, 매핑 크기 단위로 데이터가 라이트되는 비휘발성 메모리, 및 비휘발성 메모리에 커맨드를 제공하는 스토리지 컨트롤러를 포함하되, 스토리지 컨트롤러는, 호스트로부터 매핑 크기 단위보다 작은 제1 크기의 제1 데이터를 제1 어드레스에 라이트할 것을 지시하는 라이트 커맨드를 제공받는 호스트 인터페이스와, 제1 데이터가 호스트 인터페이스를 통해 수신되기 전에, 제1 어드레스를 기반으로 어드레싱되는 비휘발성 메모리에 저장된 제2 데이터를 리드하는 리드 커맨드를 비휘발성 메모리에 제공하는 파샬 라이트 리더를 포함한다.
