The ADC chip itself was actually built for loftier purposes than downloading episodes ofPlanet Earth, though. It's actually bound for the Square Kilometer Array in Australia and South Africa to help us peer hundreds of millions of light years into space, hopefully to give us a better idea of what the universe was like around the time of the Big Bang. This massive radio telescope will devour data, too. It's expected to gather over an exabyte every day when it's finished in 2024. That's over 100 billion gigabytes.
Believe it or not, 400 gigabit isn't even the fastest connection the world has seen. For that you'll have to go to the United Kingdom where researchers recently developed 1.4 terabit internet using commercial-grade hardware. That's warp speed. More here.
