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.

[-] SinningStromgald@lemmy.world 32 points 8 months ago

But then the headline would have to say "Scientists Develop Optical Disc with measly 125TB's of Storage"

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.

I like to express my storage sizes in nibs. I think that makes this a 250 teranib disk.

[-] odelik@lemmy.today 16 points 8 months ago* (last edited 8 months ago)

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.

[-] Yawweee877h444@lemmy.world 23 points 8 months ago

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.

[-] odelik@lemmy.today 4 points 8 months ago* (last edited 8 months ago)

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.

[-] KairuByte@lemmy.dbzer0.com 3 points 8 months ago

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

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.

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

[-] tuck182@lemmy.world 20 points 8 months ago

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

[-] hperrin@lemmy.world 5 points 8 months ago

Gigibytes are what Gigi stores on her CDs.

Bits are probably more useful when talking about specialized storage. Byte usually means 8 bits, but doesn't always need to, and not all data is stored in byte chunks.

A bit is the smallest piece of usable datum, so that makes sense when discussing this technology.

[-] Yawweee877h444@lemmy.world 17 points 8 months ago

Sorry to be that guy, but in this context byte is strictly defined as 8 bits, never anything else. It's a strict definition in digital.

[-] davidgro@lemmy.world 4 points 8 months ago

While I strongly agree with the idea behind your comment and gave you an upvote, at the physical layer it's not strictly true - especially for optical discs. See https://en.wikipedia.org/wiki/Eight-to-fourteen_modulation for example.

That said, capacity listings should always be the capacity of the data that can be stored and retrieved as seen by the user, and that data would be in 8-bit bytes.

[-] Prizephitah@feddit.nu 3 points 8 months ago* (last edited 8 months ago)

That’s not true either. Byte can be both powers of 10 and powers of 2. When talking about storage devices like hard drives etc. we usually refer to them in powers of 10, but OS’s usually do it in powers of 2. That’s why your hard drive looks smaller than advertised.

Bits are used for flash memory as individual chips. Assembled devices such as RAM and memory cards are advertised in bytes. I’m imagining that the same goes for hard drive platters and possibly disc media as well.

[-] Setarkus@lemmy.world 13 points 8 months ago

A byte in this context always means 8 bit though, it has nothing to do with powers of 10 or 2. The prefix of K (kilo), M (mega), G (giga) or Ki (kibi), Mi (mebi), Gi (gibi) doesn't change the meaning of "byte".

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

[-] rockSlayer@lemmy.world 4 points 8 months ago

Pb is still a standard measurement. While it's not very standard to use petabit instead of TB for data storage, it's still a recognized unit.

[-] Yawweee877h444@lemmy.world 8 points 8 months ago

Yeah "standard" was a poorly chosen word. I meant common, as bytes are much more commonly used for disk storage.

[-] cyberpunk007@lemmy.ca 4 points 8 months ago

8 bits in a byte, networks are measured in bits.

[-] cynar@lemmy.world 12 points 8 months ago

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.

[-] Blackmist@feddit.uk 5 points 8 months ago

Are disks though?

I think the last time I saw storage measured in bits was a SNES cartridge.

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.

[-] Silentiea@lemm.ee 8 points 8 months ago

I mean there's magnetic tape. It's not, like, usable. But it's also none too volatile if stored properly.

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.

[-] ptz@dubvee.org 6 points 8 months ago

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.

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

If those turn up at any sort of reasonable cost, it would simplify my home backups so much. I only have about 14TB currently on my NAS (including workstation backups) but even at that size backups are a problem. The irreplaceable stuff (about 3TB worth) is backed up in the cloud. My ripped DVDs/BRDs would all have to be reripped, other stuff I'd just have to find again or live without. I've been looking at the advancements being made in tape drives, but those are all priced for business.

They don't want us (consumers) to own anything. The world will turn up and down before this gets released to consumers.

[-] otp@sh.itjust.works 5 points 8 months ago

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.

Does it even matter when companies have dumped physical copies for streaming?

[-] SlopppyEngineer@lemmy.world 7 points 8 months ago

It would make physical sharing of data a lot more efficient instead of the old stack of floppy disks we carried around in the old days.

[-] ptz@dubvee.org 7 points 8 months ago

This is more for bulk data storage than home media.
