New record for DNA digital storage

A 5.27-megabit e-book containing 53,426 words, 11 jpeg images and one Javascript program has been encoded in DNA and then read using next-generation DNA sequencing.

A team of Harvard and John Hopkins genetic researchers used 55,000 pieces of single-stranded DNA to store the e-book. Although 5.27-megabites may not seem sizeable, it smashed the previous record for digital information storage in DNA, which stood at 7,920 bits.

The modern world is a society of digital information hoarders that will one day run out of space for its countable volumes of photos, videos, blogs and emails. Genetic storage offers a theoretical solution due to its information density and stability. In comparison to CDs and DVDs, DNA can store around 100 billion times more information, which in addition to its durability makes it an incredibly feasible data store.

One of the researchers involved in this, Sriram Kosuri, stated that costs of DNA processing is declining, giving way for further development and availability of this technology.  Get ready to replace your hard-drives!
