Microsoft’s new 10,000-year data storage medium: glass

Summary

Microsoft's Project Silica uses lasers to store data in glass, offering long-term stability. The system can store up to 4.84TB per slab, but writing speed is a bottleneck. While promising, scalability challenges exist for massive data archives.

Key Takeaways

1. Microsoft Research announced Project Silica, a working demonstration of a system that can read and write data into small slabs of glass with a density of over a Gigabit per cubic millimeter.
2. Microsoft’s accelerated aging experiments suggest the data would be stable for over 10,000 years at room temperature.
3. Writing remains a bottleneck in the system, so Microsoft developed hardware that can write a single glass slab with four lasers simultaneously without generating too much heat.
