However, DNA-based hard drives can solve that problem easily, as DNA-based storage techniques are truly revolutionary, Joinfo.com reports with reference to India Times.
A report claims that researchers have invented a brand new approach to encode digital data within DNA, thereby creating the highest-density data storage technique ever invented. Through this digital encoding technique, it is possible to store 215 petabytes (or 215 million gigabytes) of digital data in a single gram of DNA — which is roughly the amount of data stored on the Internet. If that wasn’t putting things into perspective, every bit of information stored and recorded by humans since the beginning of time can be effectively stored in a container about the size of a room.
DNA has many advantages over conventional magnetic hard drives or flash-based SSDs for storing digital data. DNA is highly dense, extremely compact and capable of lasting thousands of years if kept in a cool, dry place.
Last month, Erlich and Dina Zielinski, an associate scientist at the New York Genome Center, successfully managed to successfully encode binary data into a DNA strand’s genetic code, and then subsequently decode them into binary files that computers could read and display — with the help of Twist Bioscience, a San Francisco-based startup working on the frontiers of digital and DNA-based data storage techniques, according to a report in Science Mag.
The DNA data embedding technique worked so that the new files contained absolutely no errors, according to the research published in Science.
The only roadblock in realizing the dream of storing digital data inside strands of DNA is the cost factor — right now it takes about US $7000 to encode 2 MB of data in a DNA strand and an additionally $2000 to decode the data. As you can see, it’s insanely expensive.
But with the passage of time and enhanced scalability, the DNA storage technique will no doubt become the storage technology of the future.
