Biology wins again…
But it is the storage capacity that shines. DNA can accurately stow massive amounts of data at a density far exceeding that of electronic devices. The simple bacterium Escherichia coli, for instance, has a storage density of about 1019 bits per cubic centimeter, according to calculations published in 2016 in Nature Materials by George Church of Harvard University and his colleagues. At that density, all the world’s current storage needs for a year could be well met by a cube of DNA measuring about one meter on a side.

And on biological compute and energy density
A computer that uses molecules to solve problems uses 10,000 times less energy than a conventional computer. If made larger, these biocomputers could efficiently solve complex logistics problems that normally require a lot of time and energy.
