DNA data storage

The latest developments in data storage turn to biology. DNA sequencing, not only allows for big data to be stored for thousands of years, but allows for a more compact encoding system based on the 4 letters in the DNA bases rather than than binary zeros and ones that have been used until now. Still, the cost makes it prohibitive for now, and the fact that the sequencing make the data impossible to update within DNA make it not quite the same as a flash drive.  Read about it in  Big Data: Tiny Storage
