Beijing time on July 8 afternoon news, Microsoft this week announced the completion of the use of DNA technology to save memory about 200MB of data, including "War and Peace", as well as 99 works of classic literature. Previous studies have demonstrated that the data can be stored in DNA into. But Microsoft said the researchers had not any one-time write so much data to DNA.
Microsoft chief researcher of the project Carlin Strauss (Karin Strauss) indicates, DNA is an excellent storage medium. Compared with traditional storage technologies, DNA storage can lead to higher storage density. University of Washington are also involved in this research project. Currently, this technology is expensive and complicated to operate. However, Microsoft hopes leveraging research biotechnology industry. Because of advances in biotechnology, recent DNA reader tool costs are falling. DNA is considered to be an alternative to the tape, which is currently the standard media for long-term storage.
Strauss said: "Microsoft hopes to see whether we can develop a DNA-based end-systems to store information such a system would be automated, and can be used for business.." She said that Microsoft carry out the project the motive is that the current electronic storage devices can not keep up the pace of development of data volume growth. "If you look at the current project, we can see that we can not save all of the information within the desired cost."
IDC predicts that by next year, the global preservation of digitized data will reach 16 trillion GB, mostly in large data centers. Strauss estimated that a shoebox so much DNA is enough to save data 100 large data centers.

DNA also has good durability, especially in the dry and cold conditions. In March this year, researchers announced that it has partially reconstructed ancient human genes. These ancient human bones stored in a cave in Spain, has over 40 years of history. In contrast, data vaulting only a few decades time, and then will be aging.
The data stored in the DNA of 0 and 1 data needs to be converted into four nucleotides that base composition of the sequence. In 2012, Harvard University molecular biologist George wonders (George Church) in writing to the DNA of a 50,000 word, the amount of data less than 1MB book before it was printed on glass smaller than pollen grains chip. This year, Cheech and reports that have implemented DNA encoding 22MB of data.
Microsoft's announced, it has been successfully written to the millions of DNA 10 times the amount of data previously. Each DNA including 150 bases.
Berkeley post-doctoral researcher at the University of California Leiyinhade · He Keer (Reinhard Heckel) is also studying the use of DNA to store data. He said that Microsoft's success concern. However, large-scale use hinder DNA storage technology major obstacle is the cost, because the production of custom DNA molecules costly. "If you want people to accept this technology, then you need this technology costs less than tape. It's hard."
Microsoft did not disclose the cost of the DNA data storage project cost, which is used by about 1.5 billion bases. Responsible for the synthesis of these DNA Twist Bioscience usually every base price of 10 cents. Commercial synthesis technology to achieve the lowest cost per base 0.04 cents. Read one million base costs about 1 cent.
Strauss believes that the cost of DNA read the next few years will be substantially reduced. She said there is evidence that the decline in costs than in the past 50 years to reduce the manufacturing cost of the transistor faster deceleration, while the decline in the cost of transistors is the driving force computing technology innovation.
In 2007, the sequencing of the human genome at a cost of approximately $ 10 million, but by 2015 the cost has dropped to $ 1,000.
