23. Yottabytes in Utah

Given the facility’s scale and the fact that a terabyte of data can now be stored on a flash drive the size of a man’s pinky, the potential amount of information that could be housed in Bluffdale is truly staggering. But so is the exponential growth in the amount of intelligence data being produced every day by the eavesdropping sensors of the NSA and other intelligence agencies. As a result of this “expanding array of theater airborne and other sensor networks,” as a 2007 Department of Defense report puts it, the Pentagon is attempting to expand its worldwide communications network, known as the Global Information Grid, to handle yottabytes (1024 bytes) of data. (A yottabyte is a septillion bytes—so large that no one has yet coined a term for the next higher magnitude.)

--------
The yottabyte is a multiple of the unit byte for digital information. The prefix yotta indicates the eighth power of 1000 and means 1024 in the International System of Units (SI), and therefore one yottabyte is one septillion (one long scale quadrillion) bytes. The unit symbol for the yottabyte is YB.

1 YB = 1000000000000000000000000bytes = 10008bytes = 1024bytes = 1000zettabytes = 1 trillion terabytes.

A related unit, the yobibyte (YiB), using a binary prefix, means 10248bytes.
Examples

To store a yottabyte on terabyte sized hard drives would require a million city block size data-centers, as big as the states of Delaware and Rhode Island. (Wiki)
