A zettabyte of data vs An exabyte archive: data size comparison
The data size of a zettabyte of data is about 1,000 times the data size of an exabyte archive.
BYTES 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.
An exabyte archive is a digital storage system capable of holding extremely large datasets, often used by major organisations or data centres.

Why we use 1 ZB
We compare the data size of a zettabyte of data. This is an illustrative comparison value, not a claim that every example is the same.
A defined 1 ZB decimal amount. Data generated, transferred and stored are different quantities.
