DNA Digital Data Storage
DNA Digital Data Storage. Usually , You all have heard about computer storage devices like floppy disks, USB flash drives, memory cards, memory sticks, tape cassettes, zip cassettes, computer hard drives, CD’s and DVDs etc
Have you ever heard about DNA storage? Yes, Researchers are discovering and investing lots of efforts into new storage techniques like DNA storage. Even they are able to read the data without any error. Including 6 files, a movie and even a virus is stored on DNA strand.
Quite Interesting right? Let us know something more.
Researchers are working on DNA storage apart from working on tons of data on tiny USB drives . DNA storage have some advantages like it has high data storage capacity and long lasting ability. Companies like Microsoft are spending a lot of money on this technology.
Recently, the scientists from the Data Science Institute at Columbia University and the New York Genome Center published a new paper that showed how the DNA-based data storage technique can be used to store digital information like operating system, malware, or movie.
How DNA storage work?
From an Article we get to know “Yaniv Erlich, from California University and Dina Zielinski, from the New York Genome Center, looked for algorithms that were being used to encode and decode data. The files were converted into the binary strings of 1s and 0s. Then, they were compressed into one master file and the data was divided into short strings of binary code.
To randomly pick these short strings and reassemble them in proper order later, they developed an algorithm called DNA fountain. This was followed by the creation of DNA strands.
To decode the strands, the sequences were fed into a computer that translated it into binary and reassembled the original files. The files which were created after this process contained zero errors.”
This is very costly and unsuitable for large scale of application. The researchers had to spend $7000 to create the strands with 2 MB data and another $2000 to read it. Erlich said that “We are still in early days, but it also took magnetic media years of research and development before it became useful”.
