FACT OF THE DAY: The new National Security Agency (NSA) Utah Data Center can reportedly store up to five zettabytes of data. To put that in perspective, one zettabyte is the equivalent of about 62.5 billion iPhones. Stack those iPhones on top of each other, and they would reach past the moon.
The data center could theoretically store every email, cell phone call, Google search, and surveillance camera video in America for a very long time! Watch the report from FNC's Catherine Herridge:

How much is a Zettabyte?
Zettabyte (1 000 000 000 000 000 000 000 bytes)
Perspective?
+ According to International Data Corporation, the total amount of global data is expected to grow to 2.7 zettabytes during 2012. This is 48% up from 2011.[11]
+ Mark Liberman calculated the storage requirements for all human speech ever spoken at 42 zettabytes if digitized as 16 kHz 16-bit audio. This was done in response to a popular expression that states "all words ever spoken by human beings" could be stored in approximately 5 exabytes of data (see exabyte for details). Liberman did "freely confess that maybe the authors [of the exabyte estimate] were thinking about text."[12]
+ Research from the University of Southern California reports that in 2007, humankind successfully sent 1.9 zettabytes of information through broadcast technology such as televisions and GPS.[13]
