A method for increasing effective storage capacity in a heterogeneous storage array is disclosed. In one embodiment, such a method determines a number of smaller-capacity storage drives and a number of larger-capacity storage drives in a storage array. The method further determines which RAID arrays in the storage array may be composed exclusively of the larger-capacity storage drives. Using this information, the method establishes a first set of RAID arrays in the storage array that will be composed exclusively of the larger-capacity storage drives and a second set of RAID arrays that may contain the smaller-capacity storage drives. The method then initiates a process to swap the smaller-capacity storage drives in the first set with the larger-capacity storage drives in the second set until the first set of RAID arrays is composed exclusively of the larger-capacity storage drives. A corresponding system and computer program product are also disclosed.
