# Cerabyte **Domain:** Archival Storage / Materials Engineering **Doc Type:** Technology Node **Maturity:** Vendor Engineering and Roadmap **Related:** [[Physical Permanence Gradient]], [[Project Silica]], [[Cold Data]] --- ## Definition **Cerabyte** is an archival-storage architecture that records nanoscale patterns in a thin ceramic layer on glass using matrixed laser exposure and reads them through high-speed imaging. It targets durable, zero-retention-energy, robotically accessible cold storage. ## Evidentiary boundary Capacity, throughput, cost, access-time, and lifetime figures must distinguish demonstrated pilot results from vendor projections and roadmap targets.
