Lots of archival applications that can use this today at these speeds, assuming you’re staging the data like you would for tape. It’s slow, but permanent from a longevity perspective. You could fit 200PB of the Internet Archive in ~600 of these 5 inch glass discs. Hopefully speeds improve, along with infra to treat the media similar to an automated tape library.

It'll only take 900 years to write using a single drive. ;-)

I'll need to be at least as fast (a 100x speedup) and at least as compact as LTO.
