In a world where data multiplies at an exponential rate, traditional storage solutions are struggling to keep up. Hard drives, SSDs, and even magnetic tapes are reaching their limits, both in capacity and energy efficiency. It is in this context that researchers in China have unveiled an innovation that could redefine digital archiving: the DNA cassette.
Unmatched Data Storage Density
Imagine a 100-meter strip capable of holding 36 petabytes of data—the equivalent of 36,000 1TB hard drives. This is the promise of this technology, thanks to the extraordinary density of DNA. According to a study published in Science Advances, a single gram of DNA could theoretically store up to 215 million terabytes of data (Energy Reporters).
