Zettabyte

A zettabyte (ZB) is a unit of measurement for computers of the future. Zettabytes hold 1024 exabytes (EB) or a billion trillion (1,000,000,000,000,000,000,000) bytes, and 1024 zettabytes make one yottabyte.

A zettabyte is so large that it would take about a million supercomputers (or a thousand million powerful home computers) to store this amount of data.
