Abstract
A controller is connectable to a host system and a plurality of storage devices. A monitor unit monitors operating status of a plurality of storage devices and sets the operating status of the storage devices in a status table. Upon receiving a write command from the host system, a command responding unit receives write data sent from the host system within a certain period of time after the write command, holds the write data received in a buffer memory, instructs a timer to start counting, sets a write destination for data in the status table, outputs a control signal that gives an instruction to write data to the storage device of the write destination, and returns a write completion response corresponding to the write command to the host system when receiving the deadline notification from the timer.
