Petabyte

We all know 1 GB is the same 1024 MB, but did you know that 1 petabyte (PB) is equivalent to 1024 terabytes (TB)?

To give an example of how big this is, a 1 PB hard drive could hold 13.3 years of HD-TV video.

A 50 PB hard drive could hold the entire written works of mankind, from the beginning of recorded history, in all languages.
