Diamonds Could Store Data for Millions of Years

Researchers from the University of Science and Technology of China have developed a diamond-based data storage system capable of preserving vast amounts of information for millions of years. This system achieves a storage density of 1.85 terabytes per cubic centimeter, significantly surpassing traditional storage methods.

How It Works

The process involves directing ultrafast laser pulses at minuscule diamond fragments, causing displacement of carbon atoms and creating vacancies within the diamond's atomic structure. These vacancies serve as data storage sites, with the system demonstrating a readout fidelity exceeding 99%.

Advantages Over Traditional Storage

Compared to conventional hard drives, which typically offer around one terabyte per cubic centimeter, this diamond-based technology provides a storage density approximately 2,000 times greater than that of standard Blu-ray discs. Additionally, the inherent durability of diamonds ensures data retention over geological timescales without degradation.

Challenges and Future Prospects

Currently, the technology requires specialized and costly equipment, limiting its immediate commercial application. However, researchers are optimistic that future advancements could lead to miniaturization and cost reduction, making this innovative storage solution more accessible.

This breakthrough holds promise for long-term data preservation, potentially safeguarding the records of human civilization for future generations.
