As part of the Global Information Grid and Comprehensive National Cyber-security Initiative, the US National Security Agency (NSA) is building a $2 billion Utah Data Center facility to process (not store) yottabytes of information.

1 yottabyte = 1,000,000,000,000,000,000,000,000 bytes
                     = 10²⁴ bytes
                     = 1000⁸ bytes
                     = 1 thousand zettabytes
                     = 1 million exabytes
                     = 1 billion petabytes
                     = 1 trillion terabytes
                     = 1 quadrillion gigabytes
                     = 1 quintillion megabytes
                     = 1 sextillion kilobytes
                     = 1 septillion bytes
