An information handling system includes a plurality of storage disks arranged as a redundant array of independent disks and a controller. The controller communicates with each of the storage disks. The controller determines a total amount of storage space utilized to store parity information within the storage disks based on a smallest disk size of the storage disks and a number of storage disks in the redundant array of independent disks, calculates an amount of storage space utilized to store parity information on each of the disks based on the total amount of storage space utilized to store parity information and the number of storage disks, and allocates a parity region of sectors within each of the storage disks to store the parity information. The parity region is an inner most region of a disk.
