Meet the Super DVD: Scientists Develop Massive 1 Petabit Optical Disk (gizmodo.com)

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.

Petabit/byte is not a buzz word.

We use bits, megabits, terabits, and petabits fairly standardly in tech.

That's not to be confused with bytes, megabytes, terabytes, and petabytes. Server farms will contain Petabytes (PB) of data.

Technically there's also exabit/byte, zettabit/byte, and yottabit/byte as we continue to climb the chain of technical capabilities. It's estimated that the internet overall has nearly 200 Zettabytes(ZB) of information in 2024.

I will refrain from using the word "standard", but when it comes to data storage the most common terminology is in bytes, as I said TB(terabytes), GB, etc. Saying Pb(petabits) isn't as common and gimmicky imo when referring to a new disk storage technology. 125 TB is impressive enough without having to throw the Peta in there.

Researchers and low level technology engineers tend to work in bits. I don't have access to the full journal publication to verify, but it's likely that the journal publication used that number and that the Gizmodo author/editor that choose the title just didn't bother converting it to more "consumer friendly" terms.

However, the author did boast that it would be "125,000,000 GB!". So I'm gonna go with that this was an AI written article and doesn't really know what a technology reader would actually prefer to see.

An LLM would absolutely know what the average reader would prefer to see, that’s kinda their whole schtick.

The average (non-technical) reader would prefer to ~~see~~ click on the bigger number

I don’t think there are any storage media that advertise their capacity in *bits though.

[–] [email protected] 1 points 9 months ago

it's not a buzzword, unless you produce a storage medium using it for some reason.

Then you ask questions.
