With the growing data explosion and the dramatic growth of Big Data, the IT companies are facing surmounting difficulties to manage large set of data streams. Storage devices such as hard drives, magnetic media or USB sticks are continually facing difficulties in retaining the data for longer period of time.. Researchers have come across a new way to solve the ever-increasing problem of data storage by storing information in DNA molecules which could possibly last for millions of years. Deoxyribonucleic acid (DNA) storage has emerged to be the most current and largest form of data storage. DNA data storage has revealed promising applications in storing large amount of information in a microscopic space in a more compact manner. DNA digital data storage refers to storing digital data in the base sequence of DNA. Theoretically speaking, 1 gram of DNA has the potential of holding 455 exabytes of data.
Scientists have discovered modern information and chemical engineering tools for protecting the digital information stored in the form of DNA. Researches in Zurich have come across with new mathematical algorithms which can be deployed during long-distance radio transmissions to remove any errors seen during deciphering the digital data coded in the DNA. They also invented a new methodology with the help of which the DNA is encapsulated in glass which is much similar to making a fossilized form of data storage. This makes DNA storage as a permanent form of data storage, As per a recent report published by IndustryARC on the next generation data storage technology market, DNA Storage is projected to attain total worth of $30m by the end of 2016 and is forecast to grow at a CAGR of 50.73% by 2025.
DNA has the potential to store data for a long period of time and has proven to be the densest form of data storage, thereby likely to replace the traditional hard drives. As for example, an external hard drive can store about five terabytes of data and could possibly last for around fifty years. In contrast to this, 28 grams (or an ounce) of DNA can store around 300,000 terabytes of memory and possibly last for about a million of years. The high cost involved in DNA storage has proved to be a major obstacle in its growth. Slow rate of data retrieval and prolonged time required to read and write DNA strands are few factors that need to be addressed by the researchers before its commercialization in the data storage industry. But DNA storage does not need a constant supply of power and has no degradation issues, unlike the magnetic tapes and other digital media. DNA storage system is likely to become the future data storage medium for storing all kind of information and data, owing to its extreme stable nature and potential to store data reliably for centuries without loss and decay. Within the next five years, the rapid upsurge in the field of DNA storage is set to propel its market towards commercialization, making it available for the data storage users across the end user industries.
