Diamond Storage Technology Achieves Commercial-Grade Writing: 100TB Per Disk, Data Retention Exceeds 1 Billion Years

UK startup CarbonVault released its first commercial diamond storage device Vault-100 on April 4. The device uses nitrogen-vacancy (NV) defects in synthetic diamond as data storage units, recording binary information by controlling NV defect spin states. Single disk capacity is 100TB with read speeds of 500MB/s and write speeds of 50MB/s. Most notably, the theoretical data retention period exceeds 1 billion years at room temperature and pressure.

Vault-100 is priced at $12,000 per disk, primarily targeting clients requiring extremely long-term data archiving, including national archives, genomic databases, and space exploration agencies. NASA has ordered 100 units for storing scientific data from deep space probes. CarbonVault CEO stated that compared to traditional tape storage requiring migration every 5-10 years, diamond storage's "write once, preserve forever" characteristic significantly reduces total cost of ownership for long-term archiving.
