Storing Data Practically Forever in Glass

Here’s something a little bit different for this channel, but something that I found particularly interesting. It a video is about a new form of data storage that is being working on by Microsoft, who are working on Project Silica, a technology where digital data is stored in glass in 3D ‘voxels’ rather than magnetic ‘pixels’.

This looks like it is mainly for archival storage, rather than for working memory and storage in a PC or mobile device.

Each glass sheet can apparently hold 7 TB of data. They state here that normal hard drives are good for perhaps 5 years, tape storage for 10 years, but they expect data in glass to last for 10,000 years, (unless you drop one of the sheets!)
