" The era of digital DNA (if there ends up being one) is still a long way off. Million-fold improvements in the scale and speed of DNA synthesis are needed if it is to become a viable solution to the world’s growing data storage problem. But it is worth considering that the cost of DNA sequencing has dropped two-million-fold since 2003, a pace that exceeds Moore’s Law. And consider this: at a theoretical maximum density of 2 bits per nucleotide, all of the world’s data could be stored in a mere kilogram of DNA. That’s a lot of DNA—it’s also a lot of data! It is not difficult to envision a future in which the world’s data archiving centres are full of DNA chips instead of computer hard drives. "
