What is a Exabyte?
Definition
An exabyte (EB) is a unit of digital information storage equal to 1018 bytes (one quintillion bytes, or 1,000,000,000,000,000,000 bytes). It uses the standard SI decimal prefix 'exa-'. One exabyte is equivalent to 1,000 petabytes or one million terabytes.
History
The prefix 'exa-' (representing 1018) was adopted as an SI prefix by the General Conference on Weights and Measures (CGPM) in 1975. The application of this prefix to the byte (exabyte) became necessary with the exponential growth of digital data, driven by the internet, large-scale scientific computing, big data analytics, and the expansion of cloud storage services. It represents a scale of data far beyond what was common in earlier computing eras.
Common Uses
Exabytes are used to measure extremely large volumes of data storage capacity or accumulated data, typically in contexts such as:
- Total storage capacity of major cloud providers (like AWS, Google Cloud, Azure).
- Aggregate size of the entire internet or large portions of it.
- Annual global data creation estimates.
- Storage requirements for massive scientific projects (e.g., Large Hadron Collider, Square Kilometre Array).
- Capacity of national archives or vast digital libraries.
- Discussions about future data storage needs and technologies.
