    What a useless headline. God forbid they just give the actual capacity rather than some abstract, bullshit, flexible measure that means nothing to anyone.

      They have to make it as accessible a headline as possible, especially when most don’t read past the headline anyway these days. The average person probably doesn’t have much of an idea as to what 125TB looks like in real world use.

      Most people aren’t tech savvy, and industry acronyms chase them away.

      On the other hand, a movie is something everyone can understand.

        Not really. A 4K movie means nothing to 99% of people. Is it 4GB? 40? 400? How many can my phone hold? Or my computer?

        This only makes things more understandable if you use a point of reference that everyone you’re talking to is familiar with. The fact that they had to then explain how big a 4K movie is in the article clearly shows that even they know that this doesn’t help people. It’s just a big flashy number.

        Just for context, I’m a writer, I understand the point of using these abstract measures to give a frame of reference. But in this case, just giving the capacity in GB/TB would have been easier to understand. It just wouldn’t have been as sensational of a headline.

    1.4Pb (~175TB), the quoted number of movies is based on a 14GB movie which is very small (most BluRay disks hold somewhere between 25 and 50GB) and no discussion about write speed, so basically this is cool research that someone has done and is no closer to a commercial product that any of the dozens of other articles that have come out on this topic in the last 15 years

      And I believe 4k blurays are on average around 100 gb? So that will be about 1800-2000 movies. Still a lot, but not the 14.000 they say.

        The rips I pirate aren’t re-encoded and are usually in the range of 50-75GB, depending on the length of the film.

          Hmm, interesting. I guess on actual Blurays they would have space for extras, menus, sometimes different dubs etc, so that makes sense!

      From the article:

      What’s almost more remarkable is that the scientists say a single new blank disc can be manufactured using conventional DVD mass production techniques within six minutes.

        If this was a response to write speeds they meant the speed at which data can be written to the disc, not the time ot takes to build the disc. Read/Write speeds are a standard measure used to tell whether something would be efficient to use. For example one could say storing an OS on a DVD and booting would be dumb because it would run extremely slow, where as the read speed for playing music or a movie off it wouldn’t be an issue as it doesn’t need higher performance for such.

    I wonder what the longevity of one of these discs is? The article says they can be manufactured in regular DVD production facilities, so it probably depends on the material used (which I think can range).

    If they could combine something close to this data capacity level with the M-DISC standard (which supposedly last for about 1,000 years once you take into account the organic ingredients) that would be fantastic.

    New optical-disks able to hold a shit ton more storage sounds cool, until you realize you probably ain’t gonna be seeing widespread adoption of it among the general public due to cloud storage and things like that, so if it ever does become publicly available it’ll cost way too much.

      Yeah, that’s going to be the thing. LTO tapes/drives would be dirt cheap if the demand was anywhere near where DVDs were at their peak

    I’m imagining the RPMs on these babies trying things trying to load Gigs worth of data at a time. I like to think it will start glowing from the heat generated.

      You’re just sitting on your couch, trying to watch a movie, when your blu ray player suddenly begins to sound like a leaf blower, until a glowing hot disk of destruction shoots through the tray at fourty thousand rpm, ripping through your walls, decapitating your neighbor and taking down some sattelites in orbit

    That’s enough to store a high detail photo of every single man and woman posing naked in every possible position and combination of positions. And it lasts 10 years like parts of some CDs and DVDs did? Wow! Incredible!
