According to Technologyreview, researchers at Microsoft's research institute said the company is developing a storage device that uses biologically substituted tape drives based on early research on NDA storage movies and documents.
Microsoft Research Institute computer architects said the company has formally set a goal, that by 2020, in the data center to establish a DNA-based operating storage system. "We hope to achieve a vision of three years of storage of DNA equivalent to one data center in the raw business system," said Doug Carmean, director of the Microsoft Research Institute architect Doug Carmean. Carmel also describes the size of the final equipment, which is similar to the twentieth century 70's Xerox copier. Internally, Microsoft has a more ambitious goal of using biology to replace tape drives, a common format for archiving information. Kami said: "We want to name it & lsquo; DNA store '. & Rdquo;
These plans show that many technology companies are taking this seemingly strange idea and want to keep videos, photos, or valuable documents in the molecules of genes. Victor Zhirnov, chief scientist at Semiconductor Research Corporation, said that efforts to increase the computer memory still have physical limits, while DNA has an incredible density that can be used to store data.
In DNA, each movie is compressed to a smaller volume than sugar. "DNA is one of the most densely known storage media in the universe, and that's why people value the potential of this research, and we are solving the problem of increasing the storage of information." "In July last year, Microsoft publicly claimed that it stored 200 megabytes of data in the DNA chain, including a piece of music video, set a new record. Kari Strauss, a researcher at the University of Washington Computer Laboratory Luis & middot; Luis Ceze, published a paper on pre-printed BioRxiv, introducing their progress.
The main obstacle to the use of DNA storage data still exists, converting the digital bits into DNA coding (a nucleotide chain consisting of A, G, C, and T) is still laborious and expensive because manufacturing the DNA strand requires a long chemical process. In its demonstration project, Microsoft used 13448372 unique DNA fragments. Experts said that in the open market to buy these materials to spend 800,000 US dollars. Yaniv Erlich, a professor at Columbia University who studies DNA storage methods, says: "The main problem with DNA storage is the high cost, so the most important thing about Microsoft's solution is whether it can solve this problem." Rdquo ; After reading Cami's paper, Eric said: "I did not see any progress in helping to achieve this goal, but maybe they had more new things." & Rdquo;
Microsoft said that DNA storage costs need to drop 10,000 times before it may be widely used. Although many experts believe that this is not possible, but Microsoft firmly believe that this progress may occur, provided that the computer industry needs it. It is also important to automate the process of writing digital data into DNA. According to several weeks of experiments, Kami estimated the rate of data transfer to DNA is 400 bytes per second. Microsoft said the speed needs to be increased to 100 megabytes per second.
Reading data becomes easier and achievable by using a high-speed sequencer, including a specific part of the recall file, similar to random access memory on a computer. Microsoft believes that if DNA reading is twice improved, it can drive the efficiency of the system to meet commercial use. Since writing and retrieving data into DNA is very slow, any early use of the technology will be limited to special circumstances. This may be due to the need for archived data to exist for legal or regulatory reasons, such as police CAM video or medical records.
Microsoft is currently working with San Francisco-based DNA maker Twist Bioscience, a new company that is committed to improving DNA production. In addition to Twist Bioscience, other similar companies include DNAScript, Nuclera Nucleics, Evonetix, Molecular Assemblies, Catalog DNA, Helixworks, and Genome Foundry from Oxford Nanopore.
Some start-ups are pursuing an exciting vision of using a DNA that uses enzymes instead of a 40-year chemical reaction process, just like our own body. Jean Colot, scientific director of Technicolor Research, said: "I believe this year will see the results." "His company has always been discussing how to use DNA storage with film companies. He said half of the films before 1951 were lost because they were stored on film. There are now new formats, such as high-definition video and virtual reality, that are expanding the studio's ability to save these works.
Dirnov said that computer chip manufacturers are very important to DNA storage technology, because the traditional media (such as tape or hard disk) to store data is always a physical limit. The company is funded by Microsoft, Intel and others, who are conducting research and starting to target DNA from 2013. He said that the semiconductor experts were surprised to find that it was 100 to 1000 times longer than silicon devices. This molecule is very stable and can often be extracted from the mammoth bones and ancient human remains.
But its most important feature is high density. DNA can accommodate 100 billion bytes of information on a 1 mm square slice. Dirnov said that density is the most important & rdquo ;. A spokesman for the Microsoft Research Institute said the company is currently unable to confirm the specific details of the product plan. Within the company, the idea of DNA storage is clearly supported by many people, but has not yet been universally accepted. Cami said: "Our people believe us inside, but there are doubts about people who support tape storage. & Rdquo;
In addition to being densely durable, there are other areas of DNA storage that are not often referred to as advantages, that is, extreme relevance to human species. Think about the old floppy disks that you can not read or the clay pieces that are hard to recognize hieroglyphs. Unlike these media, DNA is never out of date. Kami said: "As long as we are still human, we can always read DNA." & Rdquo;
