An exabyte archive
An exabyte archive is a digital storage system capable of holding extremely large datasets, often used by major organisations or data centres.
How big is it?
1 EB of data

A little perspective
About 4.65 times the theoretical bytes per gram of DNA storage theoretical capacity per gram.
DNA storage theoretical capacity per gram: DNA storage theoretical capacity per gram is the maximum amount of digital information that can be encoded in one gram of DNA under ideal conditions.
Measurements, assumptions & sources +
An exabyte archive
A defined 1 EB decimal data amount; no claim about a named service.
Defined examples — our methodology
The marked data is calibrated. Unmeasured illustration details are representative.
DNA storage theoretical capacity per gram
A theoretical information density of about 215 petabytes per gram of DNA under an idealised encoding model. Real systems require addressing, error correction, redundancy, containers and retrieval machinery, reducing practical density.
Harvard Wyss Institute — DNA data storage
The marked theoretical bytes per gram is calibrated. Unmeasured illustration details are representative.

Why we use 1 EB
For comparison, this page uses data. This is labelled example: an explicit comparison model rather than a claim that every example has the same value.
