The Future of Data Storage Might be Ceramic Glass That Can Last Thousands of Years
Arthur T Knackerbracket has processed the following story:
Cerabyte recently conducted an experiment that seemed more like a culinary exercise than a technology showcase. The German storage startup plunged a sliver of its archival glass storage into a kettle of boiling salt water, then roasted it in a pizza oven.
Despite enduring temperatures of 100C in the kettle and 250C in the oven, the storage medium emerged unscathed, with its data fully intact. This experiment - along with a similar live demonstration at the Open Compute Project Summit in Dublin - was not just a spectacle. It was Cerabyte's way of proving a bold claim: its storage media can withstand conditions that would destroy conventional data storage.
Founded in 2022, Cerabyte is on a mission to upend the world of digital archiving. The company's technology relies on an ultra-thin ceramic layer - just 50 to 100 atoms thick - applied to a glass substrate.
Using femtosecond lasers, data is etched into the ceramic in nanoscale holes. Each 9 cm^2 chip can store up to 1 GB of information per side, written at a rate of two million bits per laser pulse. Cerabyte claims the result is a medium as durable as ancient hieroglyphs, with a projected lifespan of 5,000 years or more.
The durability of glass is well known. Its resistance to aging, fire, water, radiation, and even electromagnetic pulses makes it a natural candidate for "cold storage." Cerabyte's tests - including boiling the media in salt water for days (long enough to corrode the kettle itself) and baking it at high heat - were designed to underscore this resilience.
While the company has not disclosed how the ceramic layer or its bond to the glass would fare under physical shock, the media's resistance to environmental hazards is clear.
Cerabyte's ambitions extend beyond durability. The startup aims to reduce the cost of archival storage to less than $1 per terabyte by 2030 - a target that could transform the economics of long-term data retention.
[...] Unlike other archival methods - magnetic tape, hard drives, or even optical discs, all of which degrade over decades - Cerabyte's ceramic-on-glass approach promises to eliminate the need for regular data migration or energy-hungry maintenance.
