The USB DNA of the future is impressive, but the technology is going one step further with a new composition of hard drives that use genetic code to break the barriers that SSDs and HDDs still have.
Instead of taking the same route as the PlayStation 6 with the NTC to optimize storage with AI, scientists have found a way to increase capacity and speed to save critical information for the long term with molecules from nature.
It is not an exaggeration, it is truly a complex and interesting process that is becoming a reality with a discovery from the team at the University of MissouriUSA. Its operation is crucial for future advances.
How does the new DNA hard drive work?
This definitely sounds like something someone might see in a series like Netflix’s Black Mirror, but cloud storage, high-space components, and artificial intelligence are all part of reality.
Given this situation, what is the true limit of hard drives? That is the question that researchers at the University of Missouri have been asking themselves as they have the mission to overcome the space limits that both SSDs and HDDs have.
The current technology available on the market, allows you to exceed a little more than 30 terabytes (TB) and although there are many projects that even want to make yottabytes (YB) viable in the long term, what this team of researchers proposes is incredible.
As BGR explains, they have been working on a “DNA hard drive” since September 2025 and the progress is being shared by PNAS NEXUS.
Here it is stated that the process focuses on a «transcription of digital data into a universal DNA template.» During these steps, thermal microstaples are applied at a molecular scale and thus mimic the biological process «viral ribosomal frameshifting.»
To make it clear, It is not DNA extracted from humans.but of the main chemical structure. That is, it is made with synthetic DNA that is made in the laboratory and takes advantage of the fact that it already works as a natural information storage system.
The molecule is extremely efficient for memory because it incorporates four nitrogenous bases: Adenine (A), Thymine (T), Cytosine (C) y Guanina (G). On the other hand, computers require binary code.
«These systems can write, read, erase and rewrite information on universal templates without requiring enzymatic reactions or labeling, allowing DNA memory to be extended beyond static file storage to enable broader applications.»
In this way, digital files are saved in test tubes instead of using chips. The issue of efficiency and capacity is not just a comment without further ado, as it confirms that could reach up to 215,000 TB per gram without having to apply synthesis or enzymes.
As for writing and rewriting, it runs in parallel because there are no limits when leaving aside the rigid system of 0 and 1. Thanks to this it is versatile because does not work on a single «dead file» and may be rewritable.
Considering that DNA also takes up little physical space and its longevity extends to thousands of years, it would be a key to making the technological leap that has always been wanted and reducing expenses in the process.
Of course, it’s a project that’s still in development and isn’t ready for home use like a regular HDD or SSD, but your investment could pay off for long-term mass archiving for large companies.
