You could fit the data from 25 million 1TB SSDs on this 5cm diamond wafer

Researchers in Japan say they’ve concocted a new method of creating wafers out of diamonds able to store mammoth amounts of data on them.

If you assume there’s roughly 50,000 games on Steam and each one is around 80GB, which to be completely honest is probably a gross exaggeration of the average game install size on the platform, you’d be looking at around four petabytes of data required to install the lot. So with a single diamond wafer you could save the entire Steam catalogue 6,250 times.
