If you want to store data securely for a very long time, what storage medium do you choose? According to Microsoft, you should choose its still-in-development quartz glass drive.
It’s called Project Silica and it relies on femtosecond lasers to store data in a sheet of glass. As a proof of concept test for Project Silica, Microsoft collaborated with Warner Bros. to store the 1978 movie Superman on a piece of this glass, which measures 75-by-75mm and is just 2mm thick. It’s the size of a drink coaster.
