PURPOSE:To improve the performance of the write processing of data into a storage and to improve data maintenance when power becomes abnormal. CONSTITUTION:A write controller for the storage, which controls the writing of data at a high speed for the storage, is provided with a processor 10, a monitor part 50 monitoring an interface signal between magnetic disk devices 1, a memory 70 holding data which the processor 10 writes into the magnetic disk device 1 until the writing of the magnetic disk device 1 completes, an auxiliary power source 30 holding data in the memory 70 when power abnormality occurs and a control part A60 writing data or the like which is lost due to power abnormality into the magnetic disk device 1. The controller executes the write operation of data at a high speed for the storage. |
