Beijing time on April 28th morning news, Microsoft is from biotechnology Venture Company Bioscinece Twist procurement of 10 million molecules of DNA, to explore the use of biological materials to store data.
The data density of DNA is higher than that of the traditional storage device. 1 grams of DNA can store nearly 1 billion TB of data. At the same time, the robustness of DNA is very good, there are thousands of years of history of the DNA fragments can still maintain the original sequence.
These characteristics make DNA a good long-term data storage material. DNA base pair can be regarded as binary data. 2013 study showed that if you want to save more than 500 years of data, then from the economic point of view DNA has a competitive.
DNA data storage of the biggest problem is how to read and write data. Twist solves the problem of writing data to DNA. The company's equipment can create customized DNA sequence. At present, the company's main customers are research institutions. These research institutions use the technology to insert custom made genetic material into the microbes to create an organization that is used for specific purposes, such as the production of useful nutrients.
For the company, the DNA for data storage is a new area. At present, the cost of ordering the DNA sequence for each base 10 cents, the company hopes to reduce this cost to 2 cents.
Reading the data requires the use of gene sequencing technology. Over the past 20 years, the cost of this technology has dropped significantly. From 1990 to 2003, the human genome project cost about $3 billion. And the same work is currently only about $1000.
However, such a cost distance DNA sequencing of the scale of business as well as a far distance. But technology already exists. Microsoft said that the initial cooperation with Twist test shows that DNA encoding information can be extracted. If the cost of this technology can be reduced, then long-term data storage will be able to use the same technology as life itself.
