DNA Data Recording

Increased data storage density, retrieval speed and archival accuracy is always a huge IT problem as the volumes of information produced by business, science and academia continue to expand. Half a decade ago, the data demands were already somewhat enormous and growing exponentially. The Harvard Medical School in Boston recently made a breakthrough on the data storage front using DNA. Everyone always talks of the sheer capacity DNA has for storing massive amounts of information densely, however, the manifestation of using DNA for data storage has never come to fruition. Obviously, living organisms have little use for arbitrary data in their DNA and were actually killed by it. Furthermore, if the organisms lived, the natural process of genetic mutation would corrupt the data over time. Synthetic biologist George Church got around the hurdle by storing DNA fragments on the surface of a glass chip, all indexed and cross referenced against one another to ultimately store a genetics textbook as proof of concept. Other researchers utilize genetic watermarks, akin to digital ECC, in order to detect and prevent data mutation.
