A petabyte archive vs An exabyte archive
What are they, and what does the difference actually look like?
Two things. One honest scale.

What these two things are
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.
1 EBDataAn exabyte archive has about 1,000 times the data of A petabyte archive.

Measurements, assumptions & sources +
A petabyte archive
A defined 1 PB archive before replication or redundancy overhead.
Defined examples — our methodology
The marked data is calibrated. Unmeasured illustration details are representative.
An exabyte archive
A defined 1 EB decimal data amount; no claim about a named service.

- Comparing
- Data ↔ Data
- Relative size
- An exabyte archive is larger on this measurement by a factor of about 1,000.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- A petabyte archive is labelled example; treat the displayed value as a comparison anchor rather than false precision.
- An exabyte archive is labelled example; treat the displayed value as a comparison anchor rather than false precision.
