Daniel Rutter did some similar math, using MicroSD cards, since they're smaller and lighter per gigabyte.

If you fill a station wagon with them, and drive for 5 days, you'll do about 477 gibibytes per second, using 19.4 million cards, costing something like 750 million dollars.

In the real world, (he said, laughing uproariously) you'd only use a couple dozen three terabyte drives, or something, but still. For certain applications, sneakernetting can be much cheaper than internet transit.
