According to Karin Strauss, DNA is an excellent storage medium. Compared to traditional storage technologies, DNA storage can lead to higher storage densities. The University of Washington is also involved in this research project. Currently, this technology is expensive and complicated to operate. However, Microsoft hopes to leverage the research results of the biotechnology industry. Due to advances in biotechnology, the cost of recent DNA literacy tools is declining. DNA is considered an alternative to tape, the standard medium currently used for long-term storage.
Strauss said: "Microsoft wants to see if we can develop a DNA-based end-to-end system to store information. Such a system will be automated and can be used in enterprises." She said that Microsoft is carrying out this project. The motivation is that the current growth rate of electronic storage devices cannot keep up with the growth of data volume. “If you focus on the current project, you can see that we cannot save all the information at the expected cost.â€
IDC expects that by next year, digital data stored worldwide will reach 16 trillion GB, most of which are located in large data centers. Strauss estimates that as much DNA as a shoebox is enough to hold data from 100 large data centers.
The pink material at the bottom of the tube is DNA, and a small amount of DNA can store large amounts of data.
DNA also has good durability, especially in dry and cold conditions. In March of this year, some researchers announced that they had partially reconstructed the ancient human gene. These ancient human skeletons have been preserved in a cave in Spain for more than 400,000 years. In contrast, tapes hold data for only a few decades and then age.
Preserving data in DNA requires converting the 0 and 1 data into four nucleotides, a sequence of bases. In 2012, Harvard University molecular biologist George Church wrote a 50,000-word, less than 1MB book to DNA, and then printed it in a glass smaller than pollen grains. On the chip. This year, Cec also reported that DNA encoding of 22MB data has been achieved.
Microsoft announced this time that it has successfully written 10 times the amount of data in millions of DNA. Each DNA includes 150 bases.
