A disc array apparatus, having a presupposed response time, that includes several disc units for storing data transmitted from a host apparatus and an array controller for controlling a data transfer between disc units and the host apparatus. The array controller has a performance detector for detecting response times of the disc units, a correction value generator for calculating a correction value based on a difference between the response time detected for each of the disc units and a reference value, and a response timing corrector for correcting a time value at which an access end report is sent to the host apparatus at the presupposed response time, using the correction value. |
