An input-output processing system for inputting and outputting a large quantity of data comprising a logical disk control means, the logical disk control means comprises a performance data collection means for collecting data, a logical disk construction means for constructing a logical disk apparatus using said plurality of disk apparatus, where said logical disk construction means forms logical disk management data so that the stripe width is set in order to equalize response time needed for input and output corresponding to one stripe data of each disk apparatus constructing said logical disk apparatus; and said logical disk control means controls said logical disk apparatus by said logical disk management data. | |
