Harvard cracks DNA storage, crams 700 terabytes of data into a single gram

ScreenHunter_40 Aug. 21 17.12Scientists have been eyeing up DNA as a potential storage medium for a long time, for three very good reasons: It’s incredibly dense (you can store one bit per base, and a base is only a few atoms large); it’s volumetric (beaker) rather than planar (hard disk); and it’s incredibly stable — where other bleeding-edge storage mediums need to be kept in sub-zero vacuums, DNA can survive for hundreds of thousands of years in a box in your garage.

It is only with recent advances in microfluidics and labs-on-a-chip that synthesizing and sequencing DNA has become an everyday task, though. While it took years for the original Human Genome Project to analyze a single human genome (some 3 billion DNA base pairs), modern lab equipment with microfluidic chips can do it in hours. Now this isn’t to say that Church and Kosuri’s DNA storage is fast — but it’s fast enough for very-long-term archival.
