"According to SPhotonix, its current prototypes achieve write speeds of around 4 MBps and read speeds of roughly 30 MBps."

Assuming I did the math right, that means it'd take almost 3 years at max write speed to fill up the 360TB drive. So yeah, not quite ready for public consumption just yet.

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.

With these numbers the use cases seem limited to small batches of data that need the extreme durability, but to fully use this durability, you'd need to launch your archives to highly eliptical orbits that would take them to the further reaches of the solar system, because the Sun will be a white dwarf long before the warranty expires.

It might have a place in its current state,as far as write speed goes

war and peace[1] is 3.2 MB in the plain text version, so it will take less than a second to store it.
