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.

IMO the whole byte stuff is pretty confusing, people should have just sticked with bits, because that avoids implementation details.
One bit is the smallest amount of information. Bytes historically had different amounts of bits, depending on the architecture. With ASCII and the success of the 8 bit processor word of the Intel 8080/8085 processor, it is now defacto 8 Bit long.
But personally, byte seems a bit (no pun intended) like the imperial measurement system.

But then the headline would have to say "Scientists Develop Optical Disc with measly 125TB's of Storage"
Exclamation marks usually help .... and comic sans
I like to express my storage sizes in nibs. I think that makes this a 250 teranib disk.
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.
My mistake, fixed it :)

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.

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

Agreed. Bits are used more commonly when talking about transfer speeds, and bytes regarding storage.
I feel like I’ve seen bits used for storage on the scientific level since stuff like the pits and lands on a disc are expressed that way. To anyone in CS, you’d regard storage as a discrete whole part in some way. So bytes are fine. But when you’re developing storage, I believe you’d be concerned about bit density. Would need to read the paper though.

125 holy cow. drooling
I just want this disc in a DVD-RAM format.. It doesn't have to be extremely fast just readable and writable.. I used to love DVD-RAM until 4.25gb became nothing
8 bits in a byte, networks are measured in bits.
Data is stored in bytes (as the minimum size), it's moved as a bitstream (continuous flow, without regard to individual byte boarders).
Hence storage is measured in bytes, network connections are measured in bits/second.

I’m already ready to buy the 32K ultra extended directors cut of the LOTR with this news.
Lol, I feel like it'd still be a multi-disc set.
It had better be.
Let me guess, you'll watch it on your 720p TV? /s
Give him credit, it's 900p
Gonna need a new release of Skyrim too.
We're almost there...
The wet dream of all the people who pirate. This and crystal storage.
I so wish we had some affordable, high-density storage technology that we could record and then forget it in the attic for 20 years.
I mean there's magnetic tape. It's not, like, usable. But it's also none too volatile if stored properly.

They don't want us (consumers) to own anything. The world will turn up and down before this gets released to consumers.
A big part of the problem is that most consumers don't want to own things either. Subscriptions are exactly what too many people want.
I think even that goes back around to business interests. We can't store that many physical copies in shrinking, expensive housing. Digital purchasable media is somehow just as expensive despite having tiny manufacturing and logistical costs, on top of being unreliable due to DRM.
Subscriptions so far seemed like a better value proposition but between splitting and vanishing libraries, increasing prices and the addition of ads, that's becoming more questionable. Even average people aren't so thrilled of having to subscribe to a dozen different services to watch, listen and play what they want.
Whats the read write speed?
Research is one thing, getting from concept to production is another. There was a lot of hype about holographic disc formats years ago that was promising capacities from 100 GB to several TBs but they never actually made it to the market.
With the ongoing "death" of physical media playing out in the consumer space, it will also probably be hard for these esoteric disc formats to attract the investment needed to develop them. There might be some enterprise interest if the tech is stable enough for archival use I suppose.
I could see it easily replacing tape libraries as backup devices in data centers. Without the economies of scale like we saw with DVD-RW, I doubt I'd be able to afford one until they hit the secondhand market. It would also be interesting to see something like that integrated into storage appliances which would let you have something approaching an on-prem version of Amazon's Glacier tier.

That would be amazing! You could store the entire 450TB of ebooks in annas-archive on 4 of those disks!!!
