Mobile data storage device with enhanced capacity

A mobile data storage device with high storage density comprising:

• (a) a support layer comprising a first side and a second side that is substantially parallel to the first side and spaced apart from the first side by a support layer thickness;
• (b) a communication connection comprising:
• (i) a connector section comprising a connector upper surface and a connection surface positioned substantially parallel to the connector upper surface and spaced apart from the connector upper surface by a connector section thickness;
• and
• (ii) a contact section positioned adjacent an end of the connector section, wherein the contact section comprises a contact upper surface substantially aligned with the connector upper surface and a mounting surface positioned substantially parallel to the contact upper surface and spaced apart from the contact upper surface by a contact section thickness that is less than the connector section thickness, wherein a difference between the connector section thickness and the contact section thickness approximates the support layer thickness, wherein an end of the first side of the support layer is positioned adjacent the mounting surface so that the second side of the support layer is substantially aligned with the connection surface and at least a portion of the contact section overlaps at least a portion of the support layer;
• and
• (c) at least one semiconductor storage device including non-volatile read-write memory.
