    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.

        I once had to keep a $20M (technically; a million download codes for the same $20 movie for a promotion) thumbdrive in my home safe because it arrived too late to put in the safety deposit box like it was supposed to be.

        I had to remind myself a few times the practical value to anyone was about $22.

          Why did that have to be transported in a thumb drive? It can't have been more than a few hundred megabytes at the most, right?

            Enterprisey client chain-of-custody requirements. It was couriered to us, and the courier was late. Cue panicked phone calls to get an exemption to the contractual requirement for overnight storage at the bank.
