Cerabyte/Ceramic Data Solutions Holding GmbH, a German storage technology startup, is hyping up its nanolayer-based storage method: "creating the most reliable data storage ever. Data is safe in a wide temperature range of -273 °C (-460 °F) to 300 °C (570 °F) and even in corrosive or acidic atmosphere. Also radiation and an EMP can't destroy information stored on (our system)." The firm's leadership is comprised of self-described "pioneers," with a goal to disrupt the storage market (worth $500 billion)—they want to reduce data center storage total cost of ownership (TCO) by 75 %, while introducing their environment friendly solution that: "requires 99 % less energy. Sustainable long-term data storage is one of the most urgent problems in our world. Cerabyte is the solution for reducing 99% of CO2 emissions generated by conventional cloud data storage."

A product preview showcases the potential of CeraMemory cartridges (2025-30) capable of storing between 10 PB and 100 PB, and their CeraTape (2030-35) series offering up to 1 EB capacity per unit. Cerabyte representatives are set to discuss their technologies at the 2023 Storage Developer Conference, scheduled to take place later this month (September 18 to 21). Their "Ceramic Nano Memory - Data Storage for the Yottabyte Era" abstract is available to view in advance of the upcoming meet up in Silicon Valley.
 
Ceramics lasts 5,000+ years
Safe storage for generations...durable as hieroglyphs
 
Cerabyte was founded by a handful of pioneers who dared to re-think sustainable data storage from scratch. Our vision is to store all data forever and to preserve today's digital records for future use.
 
This sounds interesting. I'd like to know more.
