I don't think consumer use is even on Cerabyte's roadmap. They are proposing rack-mounted units for datacenters, and the roadmap includes upgrading from lasers to electron microscopes for higher density in the future. The media are super dense but the equipment to read and write that media is large and complex.

There was some discussion on this a few months back in this thread, as well: https://lemmy.world/post/4695105

As I noted in that other thread, they were set to present at the Storage Developer Conference in October. Looks like the video of their presentation is available now. I have not yet watched it. https://storagedeveloper.org/events/agenda/session/527

Edit: Looking through their presentation PDF, they refer to access times from 10 seconds to 90 seconds. That's whole seconds, no milli, micro, or nano. More a substitute for archival tapes than hard drives or SSDs. They don't seem to address any use case besides cold storage. I'm not saying that to dismiss or criticize the tech, just to point out that the linked article seems to be off target in its analysis, particularly in the headline.
