Data Storage in DNA Google conducted over 30 million web searches in 2019 in the world, people watched 4 million videos on youtube, sent 170,000,000 emails, tweeted 500,000 times and posted over 60,000 photos on Instagram. According to sources By 2020 an estimated 2.8 billion megabytes of data will be created per second and per person globally, which translates into about 500 zettabytes in a single year assuming a world population of 7.8 billion. The magnetic or optical data-storage systems that currently hold this volume of 0s and 1s typically cannot last for more than a century, if that. On top of this, running data centres takes huge amounts of energy. In short, we are about to have a serious data-storage problem that will only become more severe overtime. Progress is being made in an alternative to hard drives: DNA-based data storage. DNA – which consists of long chains of the nucleotides A, T, C and G – is life’s information-storage material. It is already rout
