A Petabyte is approximately 1,000 Terabytes or one million Gigabytes. It's hard to visualize what a Petabyte could hold. 1 Petabyte could hold approximately 20 million 4-door filing cabinets full of text. It could hold 500 billion pages of standard printed text.
Terabyte is 1000 times bigger than Gigabyte. Gigabyte (GB) is one of the most commonly used units of digital information which is equal to 1,000,000,000 bytes. However, in computer operating science, the value of 1 GB is considered to be equal to 230 or 10243 bytes which is equal to 1,073,741,824 bytes.
