Orders of magnitude of data

The yottabyte is a multiple of the unit byte for digital information. The prefix yotta indicates the eighth power of 1000 and means 10 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 = 1000bytes = 10bytes = 1000zettabytes.

A related unit, the yobibyte (YiB), using a binary prefix, means 1024bytes.

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. If 64 GB microSDXC cards (the most compact data storage medium available to public as of early 2013) were used instead, the total volume would be approximately 2500000 cubic meters, or the volume of the Great Pyramid of Giza.

The Utah Data Center, operated by the National Security Agency, is designed to store data on the scale of yottabytes.
