<unit, data> (PB) A unit of data equal to one quadrillion bytes but see binary prefix for other definitions. A petabyte is 10^15 bytes or 1000^5 bytes or 1000 terabytes.
As of 2013-11-05, the Internet Archive Wayback Machine contains almost two petabytes of data.
A petabyte is the amount of data that would be required to store a 2000 by 1600 pixel image of every one of the 314 million people living in the USA in 2012.
1000 petabytes are one exabyte.
