DNA Data Storage: How to Store Netflix in a Sugar Cube
Could the future of data storage be written in the same code that writes life itself? In this groundbreaking episode of Green Tech Pulse, we explore how DNA molecules could solve our massive data storage challenges while dramatically reducing environmental impact.
The Data Storage Crisis
We’re generating more data than ever before. With AI models requiring massive datasets, cloud storage expanding, and digital content growing exponentially, our current storage systems are struggling to keep up – both physically and environmentally.
As Erfane Arwani, CEO of Biomemory revealed in our latest podcast episode, data centers in Ireland alone consume a staggering 20% of the country’s electricity. This pattern is repeating globally, creating an unsustainable energy demand.
Nature’s Ancient Solution
The answer might be found in one of the oldest data storage systems on Earth – DNA.
“DNA is made of four different structures – A, T, C, and G,” explains Arwani. “When you combine them into a longer molecule, you can store data. In computer science, you have zeros and ones, but in DNA, you have A, T, C, G, and you can convert those zeros and ones.”
But unlike traditional electronic storage, DNA storage offers incredible advantages:
Incredible Density
Perhaps the most mind-blowing aspect of DNA storage is its density. According to Arwani, “In one gram of DNA, you can theoretically store 215 petabytes of data.”
To put that in perspective, that’s enough space to store:
- The entire Netflix library
- All the books ever written by humanity (approximately 138 million)
- Countless hours of music and videos
All in something smaller than a sugar cube.
Energy Efficiency
Unlike traditional data storage which requires constant electricity to maintain data integrity, DNA molecules are stable without power.
“With traditional drives or flash memories, you have to feed them with electricity because if you don’t, you will lose your data after a few weeks,” Arwani explains. “DNA doesn’t need electricity because it’s a molecule, not a charge.”
How much more efficient is it? According to Arwani’s estimates, DNA storage could theoretically reduce energy consumption in data centers by up to 10,000 times compared to current methods.
Incredible Longevity
While today’s storage media might last a few years to decades, DNA offers something unprecedented – millennium-scale storage.
“If you preserve DNA from light, oxygen, and water, you can preserve it for thousands of years minimum,” says Arwani. “But if you replicate the molecules a little bit, you can keep the data for one, two, three million years.”
This durability makes DNA storage perfect for archival purposes, preservation of human knowledge, and even interplanetary data transfer.
How It Actually Works
Despite the complex science behind it, the concept is surprisingly straightforward.
DNA storage works by:
- Converting digital data (0s and 1s) into DNA sequences (As, Ts, Cs, and Gs)
- Synthesizing these sequences into actual DNA molecules
- Preserving these molecules in stable conditions
- When needed, sequencing the DNA to read the data
- Converting the DNA sequences back into digital data
Biomemory’s approach uses synthetic biology with “petrol-free consumables” to manufacture the molecules, making the process more sustainable than competitors.
Is It Safe?
One common concern is whether DNA storage poses biological risks. Arwani addresses this directly:
“Our DNA is designed with multiple layers of protection. First, DNA is inherently offline – what we call an ‘air gap’ storage in computer science, so it’s immune to cyber attacks.”
More importantly, the DNA used is synthetic and designed to be non-functional in biological terms.
“Our DNA, even if you corrupt it or do anything with it, you can’t get proteins from it. Living cells won’t be able to do anything with it, only copy it if needed. It’s not a threat to nature or operators in data centers.”
Timeline for Adoption
While this technology sounds like science fiction, it’s closer to reality than you might think:
- Next year: Writing gigabytes per day for permanent archival
- 3-4 years: Suitable for cold storage applications
- End of the decade: Writing more than one petabyte per day
- Beyond 2030: Potential for DNA computation, not just storage
Beyond Storage: The Future of DNA Computing
Perhaps most exciting is what comes after storage. According to Arwani, DNA has potential beyond just holding data:
“The first part of what we’re building is storage, then the second part will be computing. You will be able to train your AI model for a fraction of the electricity consumption you have today with electronics – and when I say fraction, it will be five orders of magnitude different.”
Imagine AI systems that consume a tiny fraction of the energy required today, all through the power of molecular computing.

Final Thoughts
As we face growing data needs and environmental challenges, DNA storage represents a remarkable convergence of nature’s wisdom and cutting-edge technology. By learning from biology’s 3.5-billion-year-old data storage system, we might just solve one of the digital age’s biggest sustainability challenges.
