This thing is called a 5D optical data storage crystal. It's a little piece of fused quartz, etched to remarkable precision using a femtosecond ultraviolet laser.

The "5D" part of the name is just a marketing gimmick (it only has three dimensions, obviously), but it's impressive anyway. Using current technology, these little things can store 360 terabytes of data. Once written, these crystals can survive temperatures up to 1000°C, and could theoretically last for billions of years.

@InvaderXan Cool. These could be part of the libraries/ archives of the future.


@RadioAngel I was thinking specifically as a way to back up those libraries in case of catastrophes. You could fit an entire library of knowledge on just one of these things!

@InvaderXan Yup. It could eliminate library burnings which would be amazing. It would also be good for museums to have digital backups of their galleries because they tend to burn a lot too.

@RadioAngel @InvaderXan there's a lot of really cool high density storage media that have been developed. The problem, as I understand it (which might be wrong) is that it's really fucking difficult to read from them.

And, ya know, maybe you could write the Lord's Prayer on a grain of rice, but who would bother to read it?
