The only significant thing about DNA, as applied to information storage, is just that DNA is nearly as energy efficient as physically possibly[1] for storing bits of information, and therefore, it has incredible potential to encode everything. The issue, at least from the last time I heard George Church speak (~Fall 2016), is that the interface for DNA storage systems would have to be radically re-imagined, since we can't go between Digital <-> DNA anywhere near the order of magnitude as we can go DNA <-> DNA, or Environment -> DNA. Something like genetically engineered bacteria that live on the walls and have special proteins that sense and encode the environment, and count the number of unique human genomes they encounter, like a time series database (think PipelineDB) may be possible.

Basically, the idea is that for the energy used to copy DNA, DNA polymerase is very good at only inserting the "correct" nucleotide.
