Medical technology: Microsoft uses DNA storage technology to write 200M data
Microsoft today announced the use of DNA storage technology to write about 200MB of data into DNA, including War and Peace, and 99 classic literary works.
Researchers have previously shown that DNA can be used to store data. However, Microsoft said that no researchers have been able to write so much data to DNA at one time. In 2012, Harvard University molecular biologist George Church wrote a book of 50,000 words and less than 1MB of data in DNA, and then printed it on a glass chip smaller than pollen grains. This year, Church's report stated that he has successfully written 22MB of data into DNA. Microsoft announced this time that it has successfully written 10 times the amount of data in millions of DNA.
Karin Strauss, principal researcher at Microsoft's DNA Storage Program, said DNA is an excellent storage medium. Compared to traditional storage technologies, DNA storage can result in higher storage densities. Microsoft is not alone, and the University of Washington is also involved in this research project. Although currently, this technology is expensive and complicated to operate. However, Microsoft hopes to leverage the research results of the biotechnology industry to reduce costs. With the advancement of biotechnology, the cost of DNA reading and writing tools has recently declined.
Disks are the standard medium currently used for long-term storage, and DNA is considered the successor to tape. In addition to high storage density, DNA durability is also good, especially in dry and cold conditions. In March of this year, researchers announced that they had partially reconstructed the ancient human gene. These ancient human bones have been preserved in a cave in Spain for more than 400,000 years. Instead, tapes save data for only a few decades and then age.
Strauss said: "Microsoft hopes that we can develop a DNA-based end-to-end system to store information, the system will be automated, and can benefit enterprise data storage." She said that Microsoft's reason for the project is that The growth rate of electronic storage devices cannot keep up with the growth rate of data volume. "If you focus on the current project, you can see that we can't save all the information at the current cost," Strauss said.
IDC (Internet Data Center) expects that digital data will be stored worldwide for 16 trillion GB next year, most of which are located in large data centers. Strauss estimates that a shoebox with as much DNA can hold data from 100 large data centers.
