PROBLEM TO BE SOLVED: To provide a storage system, a storage device, and a storage system control method having improved data transfer efficiency.SOLUTION: A storage device 2 comprises: a plurality of NAND devices 22A to 22D each performing processing based on an instruction; an instruction management unit 212 that issues an instruction from a host 1 to the NAND devices 22A to 22D designated in the instruction, and that transmits an issuance completion notification for the issued instruction to the host 1; and a state notification unit 213 notifying the host 1 whether each of the NAND devices 22A to 22D can accept an instruction on the basis of determining whether each of the NAND devices 22A to 22D is performing a predetermined process. The host 1 includes a NAND control unit 12 that selects one of the NAND devices 22A to 22D that can accept an instruction and that transmits an instruction for the selected one of the NAND devices 22A to 22D to perform the process to the instruction management unit 212 on the basis of the issuance completion notification from the state notification unit 213 if the host 1 receives the issuance completion notification from the instruction management unit 212. |
