Note: Unfortunately the research paper linked in the article is a dead/broken/wrong link. Perhaps the author will update it later.

From the limited coverage, it doesn't sound like there's an actual optical drive that utilizes this yet and that it's just theoretical based on the properties of the material the researchers developed.

I'm not holding my breath, but I would absolutely love to be able to back up my storage system to a single optical disc (even if tens of TBs go unused).

If they could make a R/W version of that, holy crap.

It's "only" 125 TB. Still a lot, and impressive. But I just hate the stupid click baity 'petabit' term. We use bytes GB and TB as a standard, just use the standard term it's impressive enough.

Gigabytes, or gibibyte? Yes gibibyte is a thing.
As much as i hate to say it, but due to marketting fuckery the usage of byte has ruined it all as a 2TB drive is not 2 * 1024 * 1024 * 1024 * 8 bits but instead 2 terabit ( 2*1000000000 )

Then comes the discussion if "1KB" is 1024 bytes or if 1000 bytes is a kilobyte. If you ask me, 1KB is 1024 bytes. If you ask the people using the kibibytes system, 1KB is 1000 bytes...

Shits fucking complex and fucked up. Cant go wrong if you say it in bits though

"gigibyte" is not a thing, but "gibibyte" is.

Gigibytes are what Gigi stores on her CDs.
