PROBLEM TO BE SOLVED: To avoid transmission delay to the host computer for reporting the command end while reducing the pressure to the remaining capacity in the buffer memory, by taking necessary measures against vibrations detected and causing delay in reading and writing in a storage system. SOLUTION: The storage device, its controller and its data storage control method sequentially write the write command (1) data and the write command (2) data temporarily stored in the buffer memory on the magnetic disk from the time receiving the write command (4) which is the received command after detecting the vibrations until a certain time passes. It continues its sequential writing on the magnetic disk until the above predetermined time passes. After a certain time has passed after receiving the write command (4), it transmits to the host computer to report the end of the write command (4). Then, it writes the write command (3) data and the write command (4) data on the magnetic disk. COPYRIGHT: (C)2008,JPO&INPIT
