§ Product Launch
Microsoft Project Silica uses laser-modified glass to store terabytes of data for 10,000+ years. Cold storage redefined.
[Microsoft](https://startupintros.com/orgs/microsoft) Project Silica is a glass-based data storage technology that can preserve information for over 10,000 years. Announced with new milestones in February 2026, the system uses femtosecond lasers to encode data into quartz glass plates that are resistant to electromagnetic pulses, flooding, fire, and physical degradation — solving the fundamental problem of long-term digital preservation.
Microsoft developed Project Silica in partnership with Elire Group, targeting the cold and archival storage market currently dominated by magnetic tape. The global archival storage market exceeds $8 billion annually, and organizations from national archives to film studios to financial institutions face a growing crisis: digital data stored on current media degrades within decades and requires constant migration. Glass storage eliminates that maintenance cycle entirely.
For the startup ecosystem, Project Silica signals that [Microsoft](https://startupintros.com/orgs/microsoft) is thinking about infrastructure on civilizational timescales. While the technology is still pre-commercial, it opens opportunities for startups building data management, migration, and preservation tools that could integrate with next-generation storage media.
