Average cell phone call duration has decreased into less than 2 minutes.

Assuming that NSA compresses the stream under 2kbit/s, they could store 1 Billion phone calls for a year using 10 Petabytes of storage.

It's mind-boggling to fathom the storage capabilities of these systems. Then again, when $10 billion is a conservative estimate of the budget you've been given to do just this [1], it's a lot more realistic.
