A data storage system that conforms to a disk drive form factor and that can be installed into a disk drive bay of a user computer includes a plurality of such disk drive chassis user-swappably accepts a plurality of side-by-side disk drives, without tools or caddies. The metallization layer includes a conductive line; a low-k dielectric region adjacent and horizontally spaced apart from the conductive line by a space; and a filler dielectric material filling at least a portion of the space, wherein the filler dielectric material and the low-k dielectric region are formed of different materials. The slots can be discontinuous on one or both sides, openings permitting lateral insertion of the tabs at gaps, whereupon movement of the tabs along the slots engages the joint.
