A little perspective
DNA storage theoretical capacity per gram vs An exabyte archive: data size comparison
The data size of an exabyte archive is about 4.65 times the theoretical DNA storage capacity per gram.
BYTES OF DATA
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.
An exabyte archive is a digital storage system capable of holding extremely large datasets, often used by major organisations or data centres.

DNA storage theoretical capacity per gram
Theoretical bytes per gram: 215 PB; theoretical; range 100 PB–300 PB.
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.

Why this measurement?
Why we use 215 PB
We compare the theoretical DNA storage capacity per gram. This is a theoretical value calculated under stated physical assumptions, not a direct observation. The recorded range is 100 PB to 300 PB.
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.
