A thumb drive with a miniaturized memory storage assembly package that employs an extended chassis structure to support the miniaturized memory device within an ergonomically designed casing that is also simple to manufacture. The miniaturized memory storage assembly has a flexible latch projection extending from its side that mates with a complimentary latch aperture in the side of the connector housing. Downwardly projecting tongues in the top surface of the connector housing also prevent movement of the assembly within the housing. The elongated platform chassis extending rearwardly from the USB connector housing snaps in place in an ergonomically designed thumb drive case.
