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.

Why we use 215 PB
For comparison, this page uses theoretical bytes per gram. This is a theoretical scale, not a measured hard boundary or proof of a physical limit. The recorded range is 100 PB to 300 PB.
