The capacity of the media unit is divided into a plurality of zones. The media unit comprises a plurality of dies, and each of the plurality of dies comprising a plurality of erase blocks. The controller is configured to compare an estimated age of a first available erase block in each of the plurality of dies to one another and select one or more of the first available erase blocks from one or more dies of the plurality of dies based on the estimated ages to form a first zone. At least one first available erase block from at least one die of the plurality of die is excluded from the first zone.
