Petabyte

A petabyte is 2 to the 50th power, or 1,125,899,906,842,624 bytes. However, petabytes are often estimated as 10 to the 15th power, or 1,000,000,000,000,000 bytes. To avoid ambiguity, the exact calculation is often referred to as a pebibyte

Pebibyte

A pebibyte is a unit of data storage that equals 2 to the 50th power, or 1,125,899,906,842,624 bytes.

While a petabyte can be estimated as 10^15 or 1,000,000,000,000,000 bytes, a pebibyte is exactly 1,125,899,906,842,624 bytes. This is to avoid the ambiguity associated with the size of petabytes. A pebibyte is 1,024 tebibytes

A tebibyte is a unit of data storage that equals 2 to the 40th power, or 1,099,511,627,776 bytes.

While a terabyte can be estimated as 10^12 or 1,000,000,000,000 bytes, a tebibyte is exactly 1,099,511,627,776 bytes. This is to avoid the ambiguity associated with the size of terabytes. A tebibyte is 1,024 gibibytes and precedes the pebibyte unit of measurement.

 instead of a petabyte, though both definitions are commonly accepted.

A petabyte is 1,024 terabytes and precedes the exabyte

Exabyte

An exabyte is 2 to the 60th power, or 1,152,921,504,606,846,976 bytes.
It can be estimated as 10 to the 18th power, or 1,000,000,000,000,000,000 bytes. An exabyte is 1,024 petabytes


unit of measurement. Since even the largest hard drives are measured in terabytes, petabytes are only used to measure the storage space of multiple hard drives or other collections of data. And no, "petabyte" is not what you do to make a byte purr.
