With the growing amount of data, we are facing a severe problem of its storage. However, in silico storage facilities are provinding unlimited space to store a humongous amount of data. But these systems certainly have their own limits. Therefore, in recent times a new approach has been developed to store the binary information (0s and 1s) of computers in the form of ATGC nucleobases of microbes. A large amount of data i.e. ~215 million Gb of it can be stored in just a gram of microbial genomic DNA . Till now the scientists have achieved a limit of 1.8 bites of data per nucloeotide of DNA which is surly going to increase in upcoming future. One of the remarkable achievement of this technlogy has been performed recently, when scientists have encoded a digital movie inside the microbial genomes using CRISPR-Cas system, and also were able to retrieve the substatial information after culturing, harvesting, and sequencing of their engineered genomes .
Albeit, this technology has many limitations, most importantly its cost. But with growing interests and need of this field, we will soon see some neccesory developments in this aspect.
