Microsoft has purchased 10 million strands of synthetic DNA from biology startup Twist and collaborated with researchers from University of Washington to explore the idea of using synthetic DNA to store huge amount of data. The data storage density of DNA is enormously higher than conventional storage systems, as just 1 gram of DNA can store close to 1 Billion Terabytes of data. The data stored in DNA is also remarkably robust and readable for as long as 1,000 to 10,000 years. The technology is long away from ready for commercial products (so you will not see a DNA-powered smartphone anytime soon)
