“The Martian NetDrive Wireless gives you all the convenience of a local file server without any of the hassles of cables (except for power, of course, but we’re working on that). Martian NetDrives are completely silent appliances that you can place next to your stereo or even under your bed, and they’re small enough to fit on a bookshelf. Hide one in your closet or garage!”
I read somewhere once that these are becoming the favored storage devices of people with something to hide, like child pornographers and drug dealers. The theory is that they can build this into a wall in their house or something, and only connect to it when they need something. If they get raided, there’s no “cable trail” so everything stays hidden.
I don’t know how technically accurate that scenario is, but it has a nice James Bond-ish vibe to it.
