What is a petabyte?

komprise_state-unstructured-data-management-2023A petabyte (PB) is a unit of data storage that represents 1,000,000,000,000,000 bytes or 10^15 bytes. It is 1000x larger than a terabyte (TB) and one million times larger than a gigabyte (GB).

Petabytes are commonly used to describe the capacity of large-scale data storage systems, run by data heavy industries such as those used in scientific research, big data analytics, and cloud computing. For example, a single petabyte could store over 200 million 5 MB photos, or about 13.3 years’ worth of HD video content.

There are 1,000 petabytes (PB) in a zettabyte (ZB). In other words, 1 zettabyte is equal to 1,000,000 petabytes, or 10^21 bytes.

In recent years, with the exponential growth of data generation and the need for high performance, yet cost effective data storage, the term “zettabyte” has become increasingly relevant in discussions around big data and data management. It’s worth noting that even larger units of storage exist, including yottabytes (10^24 bytes) and brontobytes (10^27 bytes), but these are not yet commonly used.
