A Petabyte is a lot of data.

A petabyte is a measure of memory or data storage capacity that is equal to 2 to the 50^th 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 is 1015 or 1,000,000,000,000,000 bytes. One petabyte (abbreviated "PB") is equal to 1,000 terabytes and precedes the exabyte unit of measurement. A petabyte is slightly less in size than a pebibyte, which contains 1,125,899,906,842,624 (250) bytes.
