A data storage cartridge includes a housing, a non-tape storage medium contained within the housing, and a stacking feature provided on a top surface of the housing and on a bottom surface of the housing opposite the top surface. The stacking feature is asymmetrical about a first median axis oriented substantially perpendicular to the top surface and the bottom surface of the housing, and asymmetrical about a second median axis oriented substantially perpendicular to a first end of the housing and a second end of the housing opposite the first end. The stacking feature is configured to facilitate positioning of and maintaining a stacked configuration of the data storage cartridge with another data storage cartridge.
