摘要：
A storage device includes a control unit performing communication processing for communication with a host device connected to the storage device via a bus, a storage unit to which data from the host device is written, and a storage control unit exerting access control over the storage unit. In a first mode, when receiving a write command and data, the control unit indicates the storage control unit to write the received data to the storage unit, and if the data has been normally written to the storage unit, the control unit returns an acknowledgment to the host device. In a second mode, when receiving the write command and the data, the control unit indicates the storage control unit to write the received data to the storage unit and does not return the acknowledgment to the host device.
