    The article features a truck that the chips get loaded onto. This quote from Tanenbaum immediately jumped into mind:

    "Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway."

      I was wondering how much financial value they put in one truck. Presumably the value density of this stuff is incredibly high (although not really to anyone else, so security probably isn't a huge issue). At what point do you split the shipment between multiple trucks to avoid huge losses if there's a crash?

      When I worked on satellites we had some electronics which used a radiation hardened FPGA which cost something like $500k per chip. Carrying that around was nerve wracking.

        My buddies company shuffles chips around the west coast, some deliveries are a few million dollars. They shove the chips into the truck, then shove a giant movable wall, leaving about an inch or two gap around the perimeter.

        The truck has multiple drivers and private security.
