Intro
Nowadays the most home computers contain either a HDD or SSD to store their data. Companies, however, still rely on the magnetic tape as storage (Technology review, 2016). But all this might change in the future. It seems that the four chemical building blocks, almost responsible for all life in earth, could replace our traditional storage systems. Yes you’ve read it right: your own DNA, a possible place to store digital data.
DNA data storage
Microsoft recently mentioned that storing digital information in synthesized DNA could be a better option for the long term. The company reported that it already has written 200 MB of information into DNA, which required around 1.5 billion bases (Technology review, 2016). In practical terms of speaking; it’s a fraction of a drop of liquid.
Although the costs of the process (encoding and decoding data to and from synthesized DNA) are declining, the process itself is still cost prohibitive (Forbes, 2016). However, Microsoft’s lead researcher on this project, Karen Strauss, says that ‘DNA is a good storage medium because data can be written into molecules more densely than the basic elements of conventional storage technologies can pack it in’.
Microsoft sees it as a necessity to explore the opportunities of a DNA data storage because the electronic storage devices don’t improve as rapidly as the growth of digital data. It is predicted by the IDC that the worldwide stored data will reach 16 trillion gigabytes, most of it housed in data centers. Microsoft, on the other hand, mentions that one shoe box worth of DNA is the equivalent of 100 data centers (Technology review, 2016).
Benefits of a DNA data storage
– Only one gram of DNA can hold up to 1,000,000,000 TB of data;
– Power losses do not result in data losses;
– Magnetic fields or extreme temperatures do not degrade the data;
– It’s long-lasting. In a stable state, the medium can last thousands of years without any degradation.
