petabytes
Digital data mountains
Petabytes is the plural of petabyte, a unit of digital storage equal to one quadrillion bytes—or about a thousand terabytes.
The scale is difficult to grasp: a single petabyte could hold roughly 500 billion pages of text.
The term appears in discussions of massive data operations: The company stores several petabytes of user data, Internet traffic now measures in petabytes per day.
