A Petabyte is a lot of data.

A Petabyte is a lot of data.

At one quadrillion bytes, a  is a lot of data. The most storage you're likely to see on a consumer-level computer, even at the high end, is a couple of terabytes a petabyte is 1,000 times that (see below for a full breakdown of different capacities).

A petabyte is a measure of memory or data storage capacity that is equal to 2 to the 50th power of bytes. There are 1,024 terabytes (TB) in a petabyte -- or 1 million gigabytes (GB) -- and approximately 1,024 PB make up one exabyte.

A petabyte of storage would:

 Cost $93,662,499,307,520. Require a building the size of 10,814 football fields to hold the drives. Require 472 of the world's largest data centers to hold the drives.

Therefore, after terabyte comes petabyte. Next is exabyte, then zettabyte and yottabyte.

Petabytes (PB)

 Real-world examples: 1 PB = 500 billion pages of standard typed text (or 745 million floppy disks) 1.5 PB = 10 billion photos on Facebook. 20 PB = The amount of data processed by Google daily in 2008.

As of 2018, the yottabyte (1 septillion bytes) was the largest approved standard size of storage by the System of Units (SI). For context, there are 1,000 terabytes in a petabyte, 1,000 petabytes in an exabyte, 1,000 exabytes in a zettabyte and 1,000 zettabytes in a yottabyte
