Researchers at China's University of Science and Technology have achieved a record-breaking data storage density of 1.85 terabytes per cubic centimeter using diamonds, surpassing traditional HDDs.
The technique developed by USTC not only excels in storage density but also delivers remarkable durability, achieving write times of just 200 femtoseconds, and potentially lasting millions of years.
Significantly, the USTC's diamond storage could preserve data for 100 years even at 200°C, showcasing the thermal stability and longevity of diamonds as a storage medium.
Building on earlier work, the researchers exploited nitrogen vacancy centers within diamonds, which can exhibit stable fluorescent properties, allowing for high-capacity, efficient data storage without maintenance.
