Abstract
A method, computer program product, and computing system for compartmentalizing a plurality of RAID extents, within a RAID system, into a plurality of rotation subgroups. A write load imbalance condition is sensed in a first rotation subgroup, chosen from the plurality of rotation subgroups, that is associated with a plurality of logical data portions. At least one of the plurality of logical data portions is moved from the first rotation subgroup to a second rotation subgroup, chosen from the plurality of rotation subgroups.
