Eternal Glass : Microsoft unveils storage technology capable of lasting 10,000 years

At a time when our current hard drives and servers are showing signs of wear after only a few decades, a crucial question arises for the preservation of humanity’s digital heritage: can data be stored for 10,000 years?

Researchers at Microsoft, within the revolutionary Project Silica, claim that the answer lies in quartz.

Using ultra-precise femtosecond lasers, the scientists are able to etch information in the form of « voxels » (three-dimensional pixels) onto glass plates the size of a coaster.

Unlike traditional magnetic or optical media that degrade under the effects of humidity, heat, or oxidation, this laser-etched glass is virtually indestructible: it withstands extreme temperatures, electromagnetic radiation, and even the erosion of time, offering an estimated lifespan of several millennia.

This « cold » storage technology requires no energy to maintain the data once etched, making it a major ecological solution for global archives, national libraries, and scientific databases that are currently saturating data centers.

By shifting digital storage from the realm of the ephemeral to that of the geological, Microsoft hopes to ensure that the knowledge of our civilization, from the music of Mozart to current genomic sequencing, remains readable for future archaeologists, long after our current IT infrastructures have crumbled to dust.
