People sometimes observe that a truck or plane full of burned DVDs has much higher bandwidth than the average internet connection. That is, you could transfer a very large amount of information in a short amount of time by driving (or flying) a shipment of DVDs from one place to another. While that's true, I think it's important to include in the calculations the amount of time it takes to burn each DVD.

PS - At 20 minutes per burn, it would take days to fill a truck.
PPS - That's just an estimate.
