NSA Phone Records Big Data Photo Gallery

As Americans demand answers about the government’s wholesale electronic snooping on its citizens, the primary snooper — the National Security Agency (NSA) — is building a monstrous digital datacenter in a remote corner of Utah capable of sorting through and storing every e-mail, voicemail, and social media communication it can get its hands on.

This top-secret data warehouse could hold as many as 1.25 million 4-terabyte hard drives, built into some 5,000 servers to store the trillions upon trillions of ones and zeroes that make up your digital fingerprint.

But that’s just one way to catalog people, said Charles King, principal analyst at data center consulting firm Pund-IT.

“The NSA — like any large organization — is using numerous kinds of storage systems,” King told FoxNews.com, including “innovative SSD and in-memory systems for high performance applications like real time analytics.”
