Key Takeaways
1. Cerabyte plans to deliver archival racks with over 100 petabytes of storage and fast access times by the end of the decade using femtosecond lasers and ceramic technology.
2. A pilot system set for 2025–26 aims for 1 PB per rack, with improvements in bandwidth and latency, promising longer-lasting media at a lower cost than current magnetic tape solutions.
3. Future advancements may include helium-ion particle beams to significantly increase storage capacity to around 100 exabytes, although this remains speculative.
4. Cerabyte has secured around $14 million in investments and grants, with ongoing efforts for additional funding to support pilot production.
5. The technology is positioned as a sustainable alternative to traditional data storage, potentially reducing carbon emissions in the industry.
Cerabyte is getting ready to deliver archival racks that will have a storage capacity of more than 100 petabytes, with a throughput of 2 GB/s and first-byte access times under 10 seconds by the time the decade wraps up. The company’s method involves using femtosecond lasers to engrave nanodots into a ceramic layer that is attached to thin glass tablets, which then fit into cartridges resembling tape libraries, all managed by robotic arms.
Pilot System Goals
There’s a pilot system that is set to launch around 2025–26, which is targeting 1 PB per rack, with a steady bandwidth of 100 MB/s and a retrieval time of 90 seconds. After three rounds of updates, Cerabyte expects to see a significant increase in storage density, along with a ten-fold decrease in latency. The company claims that its media will last longer than magnetic tape—over a century compared to approximately ten years—and will offer quicker read times at a cost of about $1 per terabyte, which is half of what current tape solutions cost.
Future Prospects
Looking ahead, the roadmap includes a potential transition after 2030 from lasers to helium-ion particle beams. This could reduce the bit size from 300 nm down to 3 nm and increase the capacity per rack to around 100 exabytes, although this idea is still in the realm of speculation. Competing technologies include Microsoft’s Project Silica, holographic systems like Holomem, and DNA-based storage solutions.
Investment and Sustainability
Cerabyte has garnered strategic investments from companies like Pure Storage, Western Digital, and In-Q-Tel, in addition to receiving grants from Europe. The total from seed and grant rounds is approximately $14 million, and they are currently working on an A-series funding round to help kickstart pilot production.
Cerabyte also markets its technology as a green alternative. A market study referenced by the company indicates that replacing tape with glass-ceramic archives could reduce carbon emissions related to data storage from two percent of the global total down to about 1.25 percent.
If Cerabyte meets its engineering goals, it could provide hyperscale operators with a more high-density, low-maintenance option compared to tape. However, the transition from lab prototypes to dependable, usable hardware will be the key factor in determining if these promises become commonplace or simply remain an interesting note in the industry.
