Quettabyte

A quettabyte (QB) is a unit of measurement that has yet to be used in technology. One quettabyte holds 1000 ronnabytes (RB), 1030 (1,000,000,000,000,000,000,000,000,000,000 or one nonillion) bytes, or 1,000,000 yottabytes (YB), making it the largest data measurement unit in the International System of Units (SI).

No computer or supercomputer has yet to reach this magnitude of data, it is too large of a unit for current computing.

Background

The term "quettabyte" was introduced in 2022 to address the rapidly increasing amount of data generated and stored worldwide, particularly with the rise of big data, artificial intelligence, and the Internet of Things (IoT). As technology continues to advance, the need for such large-scale units of measurement has become essential.[source?][1]

However, there is no singular technological object as of June 2026 that can hold this amount of information.
