Some 100 trillion gigabytes of data are created and consumed each year, an amount that is expected to double by 2025. The demand for data storage carries the need for significant physical space and power requirements in the form of digital data centers. DNA, though, may represent a solution to what some see as unsustainable growth with environmental consequences. DNA, it turns out, is a dense and durable way to store information. At the end of last year, Paris-based Biomemory launched its DNA Cards, the first DNA data storage ever offered to the general public. The DNA memory cards, about the size of a credit card-sized today may seem more like a curiosity than a viable solution. At $1,000 each, they can store a kilobyte of data, enough to store a single, brief email. We spoke to Erfane Awani, founder and CEO of Biomemory, about the use of DNA for data storage, how it works, and how quickly the technology can scale to where it competes with today’s data storage infrastructure.
