In the era of digital information, realizing efficient and durable data storage solutions is paramount. Innovations in storage capacity, data throughput, device lifespan and energy consumption are pressing necessities for the continuous progression of practical digital data storage technologies. Here we present a diamond storage medium that exploits fluorescent vacancy centres as robust storage units and provides a high storage density of 14.8 Tbit cm⁻³, a short write time of 200 fs and an estimated ultralong maintenance-free lifespan on the scale of millions of years. High-speed readout through plane and volume imaging is demonstrated with a high fidelity exceeding 99%, showing that the approach addresses the practical demands of digital data storage and provides a promising solution for future storage requirements.

在数字信息时代，实现高效、持久的数据存储解决方案至关重要。存储容量、数据吞吐量、设备寿命和能耗方面的创新是实用数字数据存储技术不断发展的迫切必要条件。在这里，我们提出了一种钻石存储介质，它利用荧光空位中心作为强大的存储单元，并提供 14.8 Tbit ^cm-3 的高存储密度、200 fs 的短写入时间和估计数百万年的超长免维护寿命。通过平面和体积成像的高速读出具有超过 99% 的高保真度，表明该方法解决了数字数据存储的实际需求，并为未来的存储需求提供了有前途的解决方案。
