Allocation method of physical regions of a disc array to a plurality of logically-sequential data, adapted for increased parallel access to data
 Logical blocks are allocated to a plurality of logically sequential blocks of data by referring to disc array configuration information and a list of candidate logical blocks that may be allocated, so that the drives for retaining the logical blocks assigned to the blocks of data and the drives for holding the parities for these logical blocks will be all different. Thus, a total number of drives which operate in parallel for executing sequential writes to the disc array can be increased to a maximum extent.
