The present disclosure relates to a storage device and a storage system. The device comprises a storage, a storage controller, a control module, and a buffer module. The control module is configured to: when receiving a data read-write instruction, update the data read-write instruction by using a virtual address; apply for K buffer units in the buffer module; perform a write operation on the K buffer units by using data to be read and written; and when any of the K buffer units is full, directly start data transmission of the full buffer unit. By using the virtual storage address and by employing data block management, the present disclosure can update and forward an NVMe I/O command without applying for a storage space in advance, and can start data block transmission without checking the completion message.
