<p>A storage device, such as a direct access storage device(20), is partitioned into a plurality of partitioned devices (40 and 42, 44) having different access and storage characteristics matched to the required performance. Data may be stored on that partitioned device which most nearly meets the storage characteristics of the data, where the access and storage characteristics of data are related to its volume and frequency of access.</p> |
