Microsoft’s Project Silica has seen some advances in recent times, prompting speculation about the application and the future shape of long-term data storage hardware.
Microsoft’s recent press release from February 18, 2026 describes the project in some detail; magnetic tapes and hard drives “degrade within decades,” which has spurred a search for a better long-term alternative for data retention.
The solution Microsoft has been floating for a while has been encoding information on glass panes. To see how long the data remains intact, scientists at Microsoft used accelerated ageing tests in which they “bake” the glass at extremely high temperatures to simulate the passing of thousands of years. They found the data remained stable even at 554 °F (290 °C), meaning it will last well over 10,000 years at normal room temperatures.
The newest breakthrough involves reproducing the results using low-cost borosilicate glass rather than fused silicate. This reduces barriers to adoption, making it more likely we’ll see it in practical applications in coming years.
Why does this matter?
As mentioned earlier in this article, hardware degradation is a known concern. When discussing long-term storage – as with archiving – the storage medium failing is something that has to be kept in mind, and a new cheaper and more reliable alternative may be greatly valued by certain sectors.
For now, it remains an experimental technology under research. But chances are, we may see future data centers built in glass.
