The exponential growth of global digital information has placed unprecedented pressure on humanity’s storage infrastructure. In 2012, data volume surpassed the global first zettabyte (1021 bytes), and by 2016, network traffic had already reached this mark (1). Storing this information not only requires massive physical space, but also has a significant energy cost, consuming about 2% of global energy in 2015 (2).

Projections indicate a dramatic acceleration, with estimates of 175 zettabytes generated globally by 2025 and growth close to 400 zettabytes by 2028. This trend forces the search for long-term storage alternatives, creating a niche of high interest for innovation. Among the most promising emerging technologies for this is the DNA (deoxyribonucleic acid) molecule.

Conceptual Milestones and Technological Development

The concept of storing digital information in DNA is not new. The first documented conceptual milestone came from a 1999 art project called “Microvenus,” where artist Joe Davis, in collaboration with Harvard researchers, encoded an image of a Germanic rune into a DNA sequence and inserted it into the bacteria Escherichia coli (3, 4).

Competitive Advantages of DNA Storage

ADN offers a set of advantages that position it as a potential replacement for current data centers:

1. Extreme Density:The storage capacity is incomparably high. A single gram of DNA can store up to 215 petabytes (2.15×1017 bytes), which, in visual terms, represents the ability to house all the world’s knowledge in a shoebox.

2. Long-Term Durability: DNA can preserve information for thousands, or even hundreds of thousands of years, under proper storage conditions, far exceeding the lifespan of magnetic tapes or hard drives.

3. Reduced Physical Footprint: Allows you to replace large data centers the size of a football field with a solution the size of a football, alleviating concerns about physical space consumption.

Challenges and Future Perspectives

Despite hisinherent advantages, DNA storage technology faces a main challenge: the cost of synthesis.

High Cost of Synthesis: Currently, the cost to synthesize DNA remains prohibitively high, estimated at approximately $3,500 USD per megabyte.

The main technological and commercial obstacle is to make the storage service for large amounts of data profitable and cost-effective. However, the exponential reduction in DNA synthesis costs, driven by the genomics industry, is expected to make this technology economically viable in the long term.

It is essential to highlight that DNA as a storage method is intended for a specific market niche: large volumes of data with a low frequency of long-term access. This includes library archives, historical records, government information, and preservation archives, where the priority is longevity and density, rather than instant read speed.
