Cisco estimates that total internet traffic currently averages 167 terabits per second. FedEx has a fleet of 654 aircraft with a lift capacity of 26.5 million pounds daily. A solid-state laptop drive weighs about 78 grams and can hold up to a terabyte. That means FedEx is capable of transferring 150 exabytes of data per day, or 14 petabits per second—almost a hundred times the current throughput of the internet. …

Cisco estimates internet traffic is growing at about 29% annually. At that rate, we’d hit the FedEx point in 2040. Of course, the amount of data we can fit on a drive will have gone up by then, too.
