Microsoft has advanced its Project Silica, a novel data storage system that uses quartz glass to archive information. The technology writes data using lasers into hundreds of microscopic layers inside a coaster-sized piece of glass, achieving roughly 2 terabytes of storage in just 2 millimeters of thickness. Microsoft has already demonstrated the system by storing the original Superman movie.
The key advantage is durability: unlike hard drives, tapes, or cloud infrastructure, Project Silica requires no electricity, cooling, or maintenance. The glass can withstand heat, water, scratches, magnets, and time. This could transform long-term archival storage for data centers, media libraries, and institutions that spend heavily to preserve aging files. If commercialized, Project Silica could turn storage from a fragile operating cost into a near-permanent medium built to last centuries or longer.
