I’m not in the habit of keeping my portable hard drives next to the bathtub, but if I did, the SH93 from A-DATA would be a legitimate contender. These new portable HDDs can last up to 30 minutes when plunged into one meter of water. And hey, not only is it water-resistant, but it’s durable in other ways.  The rubberized coating can survive the military MIL-STD-810F drop test, so you know it’s solid, right? 

No word on pricing or availability as yet, but they will come in a red or yellow finish in memory capacities of 240, 320, 500, and 640GB.
