Abstract: Presented herein are methods, non-transitory computer readable media, and devices for maximizing parallelization in a parity de-clustered and sliced disk RAID architecture implemented on at least one hard disk drive by creating at least one allocation group, each created allocation group comprising at least one parity group within a sliced disk group, selecting one of said at least one allocation group, and performing at least one of write or read concurrently on all parity groups within the selected allocation group.
