That is just a little larger than Facebook's current site in Lulea in
Northern Sweden. They say "exabytes or more"; so let us assume 10 exabytes
worth of storage. (Which would push the envelope for what is possible
with the allocated incoming power).

At ~50 terabits/second (a guess to the traffic passing through
the US, with about half as average) you are talking about 3-4 terabytes
per second, 24/7/365. Or a third of a petabyte per day, giving that
exabyte in around a decade.

Yep, it seems it all goes into storage there.

But actually accessing it is another matter. Anything more than 
a few tens of millionths in actual processing for analysis would break
the bank on available power. But that seems like a rational approach
given what mandates the NSA has, at least publicly. Store it all, 
but be selective about what is analysed in depth.
