Abstract
Described are techniques for storing data on disk drives. Each disk drive platter of each of the disk drives is partitioned into two separate regions whereby a pivot point denoting a radial distance from the center of each disk drive platter is a boundary partitioning each disk drive platter into the two separate regions. A data portion is classified in accordance with an expected activity level of the data portion. Storage is allocated for the data portion in one of the two separate regions of one of the disk drive platters of one of the disk drives in accordance with the expected activity level of the data portion and a defined allocation flow.
