Either case, I doubt it is "15% of the internets current data rate" as they claim. E.g. the newish submarine cable between the US and Japan has 60 Tb capacity. And that's just one cable.

A large chunk of that capacity will be for private use, not for the capital-I Internet. 280Tbps is about right for interdomain Internet traffic, it lines up with Cisco's predictions/measurements: http://www.cisco.com/c/en/us/solutions/collateral/service-pr...

What private use requires that much bandwidth?

[neolefty]

To clarify definitions, data rate will always be less than or equal to capacity. In practice, average rate will be much less than peak capacity.

Also, that is the raw output from the antenna array. This is then analysed before storing, compressing it down to a much more managable few GB/s.

[plugger]

It's analysed and stored in Melbourne, Victoria. The SKA Pathfinder is in Western Australia outside of Geraldton. Hence the data transfer statistics as the two sites are roughly 4,000km from one another.
