Abstract
A method includes storing a data group in a first zone of a plurality of radial zones of a data storage disc. Each different one of the plurality of zones has a different throughput level. The method further includes obtaining information related to an access frequency of the data group stored in the first zone of the plurality of zones. Based on the information related to the access frequency of the data group and the different throughput levels of the different zones, a determination is made as to whether to migrate the data group from the first zone of the plurality of zones to a second zone of the plurality of zones.
