A groundbreaking optical storage technology developed by Dr. Nicolas Riesen’s team at the University of South Australia has the potential to revolutionize archival storage costs. By manipulating fluorescence in specific wavebands, this innovative method allows for multi-bit storage similar to NAND flash technology. Using nanoparticles within the recording medium, the technology encodes data in multiple levels, enabling high-density storage. Optera Data, founded by Geoff Macleod-Smith, aims to commercialize this technology, offering optical discs for high-density archival storage at a remarkable cost of $1 per terabyte. With a focus on offline security and long-term data preservation, the startup projects the development of 1TB discs in the near future, with a lofty goal of achieving 10TB for just $1 by the end of the decade. This cost efficiency could potentially disrupt the market dominated by traditional storage solutions like magnetic tape. The compatibility of this technology with existing optical disc formats makes it an attractive option for data centers seeking to reduce energy consumption and storage costs. However, its success will hinge on meeting storage density requirements and competing with emerging alternatives like synthetic DNA storage.
