What is a Petabyte?
On Thursday, 25 October, hundreds of Internet Archive supporters, volunteers, and staff celebrated addition of the 10,000,000,000,000,000th byte ( 10 Petabytes) to the Archive’s massive collections.
Every geek dreams of being in a server room full of petabyte racks. Each one of those 1U red boxes contains 4 750GB HDs. Each one of those racks has 40 of those red petaboxes. Each of those racks adds up to 120 terabytes. Those boxes power the Internet Archive (archive.org). 3 PETAbytes (3,000,000GB) of low power, compact storage from Capricorn Technologies.

A petabyte (derived from the SI prefix peta- ) is a unit of information equal to one quadrillion (short scale) bytes, or 1 billiard (long scale) bytes. The unit symbol for the petabyte is PB. The prefix peta(P) indicates the fifth power to 1000:
- 1 PB = 1000000000000000B = 10005 B = 1015 B = 1 million gigabytes = 1 thousand terabytes
