A data storage device is disclosed comprising a plurality of disk surfaces, and a head actuated over each disk surface. For each disk surface, a quality metric is measured at a plurality of discrete areal densities including a first areal density comprising a first radial density and a first linear density, and a second areal density comprising a second radial density different from the first radial density and a second linear density different from the first linear density. Based on a target capacity, an areal density is selected for each disk surface such that the combined areal densities satisfies the target capacity and such that the quality metrics across the disk surfaces are substantially equal and substantially maximized.
