Everyday quantities

An exabyte archive vs A zettabyte of data

What are they, and what does the difference actually look like?

Two things. One honest scale.

Meet the pair

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 EBData

A zettabyte of data

A zettabyte of data is a term used to describe an immense quantity of digital information, often in the context of global data generation or storage.

1 ZBData

A zettabyte of data has about 1,000 times the data of An exabyte archive.

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.

A zettabyte of data

A defined 1 ZB decimal amount. Data generated, transferred and stored are different quantities.

Comparing
Data ↔ Data
Relative size
A zettabyte of data 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.

  • An exabyte archive is labelled example; treat the displayed value as a comparison anchor rather than false precision.
  • A zettabyte of data is labelled example; treat the displayed value as a comparison anchor rather than false precision.
