Abstract: A portable data storage device with shock resistant features. The portable data storage device constructed in accordance with the present invention includes an enclosure, with a data storage module mounted therein. An elastomeric shock absorbing snubber at least partially encases the data storage module. The portable data storage device includes a printed circuit board in electrical communication with the data storage module, and a Universal Serial Bus (USB) connector in electrical communication with the printed circuit board. A retainer that defines a central ventilation aperture, a front side, and a back side is mounted to the enclosure. A subassembly including the snubber and the data storage module is engaged to the front side, while the printed circuit board is engaged the back side. The ventilation aperture partitions a subassembly including the data storage module and the snubber and the printed circuit board in a spaced relationship.
