I thought the main advantage of DNA storage was the physical size of it, and how many different genomes you could have stacked next to each other in the same -70degree space.

Millions of chimeric cells on the same petri dish? That's 1PB on a single glass slide.

Depending on the sequencing tech paired with the rise of Spatial data, the read speed could be formidable.

Needlessly complex setup though. Let's just stick with metals for now.
