      It’s just one company, it’s not all the Blu-ray production stopping. I think the last time I bought any Sony recordable media was CD-Rs for my MP3 CD player in the mid 00s.

        I always preferred the rips fork Blu rays though. They had the highest quality video and audio and stuff. This sucks so much =(

      How do SSDs and HDDs compare to optical disks in terms of stability in storage? SSD bits can lose charge over time until a lot of 1s read as 0s, right?

        SSDs are pretty pricey for video. I use HDDs, mirrored. For some uses I put a SSD caching layer on top to speed up frequent R/W. Using only LVM, no fancy RAID hardware or anything.

          I upgraded my datahoarding server to a pair of 18TB hard drives on ZFS with mirroring a little while back. It’ll be several years before I need to upgrade again, but I expect that when I do, SSDs will be cheap enough to go that route.

          Already have a 10Gbps fiber connection to that server, so the hard drives are the bottleneck.

        Commercially pressed discs don’t last forever, but longer than burnable discs. IIRC, they used to say 50 years for CDs, but in practice, it was a lot less. More like 20 or 30 if you store and handle them nicely. Easily less than 10 if you don’t.

        Hard drives go bad over time; I don’t like trusting spinning platters much over 7 years. They can be OK, but they can suddenly stop working whenever.

        SSDs are about the same as spinning platters.

            I wouldn’t trust it that way, no. They might last decades. They also might not. It’s a gamble on any single drive, or even a few mirrored drives.

            File system also matters. Modern ZFS has error checking that can handle some level of bit rot. Older formats generally don’t.

            If it’s over 7 years or so, I want to get the data off of there.

              Hard drives break down from use, not from sitting around. We aren’t talking about SSDs which while they don’t break down will experience data corruption over time. It’s not really a gamble at all with mirrored drives.

              You’re also telling me things I already know. I already use ZFS. I agree that you should be using something with data integrity protection. Though ZFS isn’t always what you want for archival purposes.

                Magnetic platters absolutely do break down from sitting around. Bearings and other mechanics can also go bad. For those things, a professional recovery operation could still get the data if you’re willing to pay, but the drive itself should be thrown out.

                Edit: keep in mind that with bit rot, the drive may superficially function just fine. Your data may even be 99% correct. That 1%, however, could cause unrecoverable problems, such as videos that glitch in the middle.

                  That’s why you use multiple drives with bitrot protection. Modern SSDs and HDDs have protections against bitrot built in, including internal checksums.

                  If you are running your hard drives once in a while, then bearing failure isn’t really a concern. You probably should be doing that anyway to refresh the data and make sure it doesn’t degrade. Regardless people have had 10 year old drives of older spin up first time. It’s not likely you are going to have a mechanical issue on multiple drives anyway.

                  If you refresh an SSD once every couple of years it will last decades.

                  You keep doing this thing where you presume I don’t know about some issue. Rather I know about these things, but they have fairly easy mitigations or are already solved.

      I guess hard drives and SSDs don’t count as physical somehow?

      Even on a streaming service, the files are stored physically somewhere.

      All media is still, technically, physical media.

      Even when you stream it locally and don’t have access to the file itself, it physically lives in your RAM for the duration of the stream.

        No one is arguing this. You’re making the strawman arguement. The not-so-subtle undertone of the article is clear.

        Quoting the article:

        The planned job cuts come amid a decline in demand for traditional storage formats such as Blu-ray discs, with streaming services now the norm.

        The electronics and entertainment conglomerate will also gradually cease production of optical disc storage media products, including Blu-ray discs, according to the sources.

        You will not be allowed to legally own tv shows or films and you should learn to like it. As I can tell from many of the other comments here, not many of us are fans of that idea.

                No, the data is not physical, it is either magnetic or electric.

                Since most people still store their media on hard drives most media is purely magnetic.

                In a solid state drive storage chip the data is stored electronicly.

        I mean, except it’s not a conspiracy. The death of physical media is an actual tragedy because digital media is nowhere near as free.

        It’s to the point where much of the media I love is actually not available legally and officially for physical ownership, in some cases becoming actual lost media physically, and not available for purchase or even download anymore.

        Companies absolutely want to control the consumption of media in more restrictive ways that they can control, it’s not a conspiracy, it’s the actual truth.

        DRM, always online, digital only, subscription services - they are all designed to remove you further and further from being an owner.

        Everything from video games, music, movies…all entertainment media is moving in this direction and it’s an actual tragedy.

            If you think the demand isn’t there, you’re out of touch. It’s certainly true that many consumers are choosing digital content, but it’s largely driven by it not having inconvenienced them so far too.

            Everyone I’m seeing who lost the 3DS and Wii U stores, or lost access to all the games in their account, or even people who purchased media they can’t download and access again is realizing how big this problem is.

              I found 8 brands of DVD±R discs—none of them Sony—before I stopped counting. If you think one company stopping production is going to stop people from using physical media, or that demand hasn’t been falling for years, YOU are the one who’s badly out of touch.

              Let me spell it out for you: as long as there is demand, someone will find a way to make money filling it. No company, no matter how evil it is, can remove a product category from the market just by leaving the market. Suggesting that a company choosing to stop making a commodity product is an attempt to prevent you from having access to said product is nonsense no matter what company and product you’re talking about, because such a plan could never work.

                Pressed discs (like movies) are physically… pressed. They make a metal mould which is then stamped into melted plastic to make the pits and lands and then coated with a metal film to make the reflected backing, filling in the pits. This makes manufacturing of millions of disks extremely cheap since it takes seconds per disc. Burning commercial disks individually in thousands of burners would be way too slow/expensive.

    Keep in mind that though this is a blow to the industry, it’s not like optical media is just yet dead. Hell, there are still new releases to DVDs coming out today.

          If I wanted to watch movies destroyed by compression, I’d go streaming. Blu-ray allows for way less compression. There’s a reason Blu-ray remuxes aren’t DVD-sized. Heck, some movies don’t even fit on a single layer Blu-ray! Do you want to compress that to 4.7 GB? And that’s only main title, without extras!

      Space jam 3! And independent film featuring bugs 🐛 and a 🐇 bunny. The Matrix Housing Crisis… A film featuring Keanu as the one. He doesn’t collect enough retirement money so he’s out there pushing a cart. We saw a preview of him in “the matrix”. That bum in the subway… anyway good movie 😂.

    So that they can fully control the fate of digital media for “normal” people. Better not lapse on that subscription or fail to upgrade to the latest Sony TV… “Your” media library might not like that, be a shame if you lost access to those pretty titles you love…

      Found a small part of the problem.

      Physical media is dying because the majority of people think just as short sighted as businesses do. Businesses think in short term thoughts like quarters. They do so because investers want immediate return.

      But why would you as a person not want physical media??? I literally bought a George Carlin dvd of one of his HBO specials 2 days ago. It was traded into a local resale shop as “used”. It was brand new, because even though the plastic wrap was gone, the adhesive label at the top was still unbroken. Brand new dvd. $3.

        Most people don’t know how to switch between inputs on their TVs or have gotten rid of their DVD or BluRay players at this point.

        They’re using the built in streaming apps or they’ve plugged a Roku in where the cable box used to go.

          dont know why youre being downvoted, this is completely true. The majority of people favour the convenience that streaming has represented, and TVs have been designed to turn on showing a shiny netflix icon instead of “Composite II” for like a decade now.

          Yes, while consumers have been sold a double-edged sword/lie - the streaming companies were obviously never going to market their platforms by saying “one downside of streaming is we can take away content whenever we like”.

          The average person with a bluray collection is going to be much more aware of the pros and cons of the formats - I’d be willing to guess most peoples family “collections” are still on DVD.

            With very little initial work, physical media is also very convenient.

            I buy a disk, put it into a specific drive, get a instant message when its ripped, check its name and put it into a folder. From there my mediabox converts it to a managable size and adds it to the collection.

            Whin I turn on my TV I see all these Movies and shows neatly presented by Kodi. I have a tiny Wireless keyboard and can start any in under a second. No buffering, no adds, no matter if the router is connected, and no fear of ever loosing access.

            Its great.

            Exeptions are there of couse, I would love to buy The Orville, but they just don’t want my money!

        For me, physical media takes up more space. It’s a good thing and a bad thing. It takes up more space which means I need to have more space, but it’s also cool having the boxes and box art etc. Ultimately, as long as I own my media and it’s physically accessible to me (like located on my hard drive), then I am happy with that ownership and don’t have to worry about it being taken away from me. Also, physical media can be damaged which means it’s unusable entirely. With a proper RAID setup and backups, digital media can outlast physical media.

          Blu-rays do not actually take up this much space: On a 1TB drive you can store about 10-12 4K movies. You need a backup and you need a second drive for your Raid setup. This takes up quiet a lot of space too.

          Besides that: storing the movies on a Raid system is a lot more expensive. If I’d rip all of my blu-rays to a digital copy, I’d need like 12 TB of storage. In a raid setup with backup, that’s quiet expensive!

            I meant physical size, not data size. With one computer with multiple 24TB drives, you can store hundreds or thousands of Blu-rays. To have that amount of physical Blu-rays, you would need a massive shelf - or more likely, multiple massive shelves.

            True, RAID is more expensive, but it also ensures your data will keep working reliably - and it’s much harder to lose than a small disc. Doubly when you throw backups into the mix.

              It’s not that big, the cases are much smaller than DVD cases. Each case is 12-13mm wide, so on a typical shelf, you could fit >60. You can easily make them two or three deep, depending on your shelf.

              I just stick them in a box after ripping them to my HDDs.

                Sure, but with a full-sized PC tower, you could reasonably fit thousands of Blu-rays. The physical size difference is pretty massive in that comparison.

                  Sure. I’m just saying storage doesn’t need to be overly burdensome. I just toss mine in a box and stick it in a closet. And if the drives die, you have the disks.

        I don’t want physical media because it’s a liability. It can get lost or destroyed very very easily, especially optical media.

        Digital copies are portable, I can data hoard them, and, worst case, I can just re-download it.

          It’s very easy to make digital copies of physical media. The resulting copy is likely to be as high quality as you can find, and as portable as any digital copy can be. Pop it in a folder and point Jellyfin at it, and it’s available anywhere.

          It’s also the easiest legal way to get a good digital copy.

            And why on earth would I pay for media when I can get it for free?

              Because somebody has to create that media. And that person they have to live. (Or better that huge team when it comes to movies) So they have to earn money, so somebody has to pay them.

              I also enjoy that today I can test if something fits me If I am skeptical. But I also always make sure to pay back creators for things I enjoy so that in the future there will be more things I enjoy.

              Of course I understand anybody who can not afford media and am happy to subsidize them with the part I am paying for good shows. But if you have a Plex server, you can afford it. And If you say its close just start with things you like most and at least say “thank you” to them.

                The creators get paid when they do the work, not from sales.

                Also, a much more important note: if I couldn’t pirate it, I wasn’t going to pay for it anyway.

      They’re a very common form of personal backup. A few discs and an USB writer and you get a very long lasting medium for passwords, personal files, family photos etc.

      Can also archive multimedia of course, the smallest discs are 25 GB and can pack a few films, a season of a series, or a lot of music.

        i guess, but they’re not great for backup. Eps. R/RW optical media doesn’t last that long (5-10 years) and is easily damaged. You’d be better off with tape for long-term storage. or an M-Disk or some similar magnetic backup solution.

          I beg to differ. I’ve been backing things up to optical for 25 years now with minimal issues. CDs could be easily scratched but it hasn’t been the case for DVD and BR.

          M-DISK uses in-organic substances that make the discs mostly immune to exposure but it’s a more recent invention. Proper storage and handling still goes a long way towards protecting discs even if they’re not in-organic.

          M-Discs had merit in the DVD era. It’s a common refrain of those who don’t know the intricacies and read a wired article years ago to claim they mean anything in the Blu-ray era. They don’t.

          Standard Blu-ray Discs have all the technologies that supposedly make m-discs so long lasting and as far as media that isn’t continuously updated and hashed from live storage medium to live storage medium (cold, archival storage unpowered) they are about as good as you’ll get.

          They are much tougher than DVDs. Of course a variety of things go into how long a disc remains readable and without damage to data including luck with regards to no impurities in the batch. Even m-disc themselves based their longest claims off storage in ideal situations like an inactive salt mine (commonly used for archives by governments). Kept out of sun, away from extreme heat (including baking in uninsulated 120 degree F heat all summer year after year), away from high humidity and away from UV exposure to the data side of the disc as well as scratches and such and they should last a quarter to half a century, some more.

          In the Blu-ray era m-discs are just an overly expensive brand.

            Politely disagree. M-disc for BD-Rs are still absolutely worth the money if you want to properly archive something. NIST has agreed that the archival lifetime of a M-Disc BD-R is 100+ years.

            You have to be careful with normal BD-Rs because there are two different types of recording material on the market: High to Low and Low to High (LTH). You want to stay away from BD-R LTH discs as their longevity isn’t as good as the High to Low discs.

              Politely agree to disagree and I’ll elaborate. Thanks for your input.

              LTH are all marked as such. MABL normal (non LTH) discs such as verbatim sells for less than half the cost of M-Discs have the same physical properties as M-Discs, the protective layers are the same, the recording methods are the same using the same materials. Therefore the longevity is the same or near the same without getting into M-Disc’s ridiculous marketing claims of 1000 years (when NIST and others agree the poly-acrylic protective layer would degrade and decompose after a century or two at most even in ideal circumstances).

              /r/Datahoarder has had this argument several times and the consensus so far seems to comes out to the fact that M-Discs were a DVD-era innovation that in the BD era offer no meaningful advantages in technologies.

              I’d rather have two BD’s from a reputable company like Verbatim (not fly by night plain white discount bulk BD’s from who knows where) from separate batches bought 6 months apart stored properly than rely on one overly expensive M-Disc that isn’t going to last any longer and probably isn’t made to meaningfully tighter tolerances.

              NIST only estimates the lifetime of M-Discs, real world abuse tests on BD’s (non LTH, should have mentioned that to be honest) show good endurance that far exceeds DVDs. It comes down to however burning it right and storing it right. A pile of M-Disc left in a window in your uninsulated garage year after year and burned at 16x are not on the whole going to be in a better state in 20 years than a pile of BD-R’s burned at 4x, stored in protective sleeves in a case in a temperature controlled, insulated environment. Add in having a back-up copy and the chances of total data failure on both primary and backup disc and you’re looking at better survivability. NIST numbers generally assume things like storage in archival quality environments such as old salt mines which are a controlled environment, low humidity, neither excessively hot or cool and not subject to shifts in temperature. Most people can’t store things in an environment like that and those who can usually have the finances for a better solution like multiple tape copies and/or continually updating and refreshing hashed/checksumed files and moving on a schedule to new better storage mediums (e.g. keeping files in a raid array in a plugged in NAS, checking for failures regularly, replacing disks and upgrading disks every 5-10 years one at a time).

              I wouldn’t trust any media not professionally stored in a purpose-built archival environment and with at least two copies to last more than 25 years without degradation or loss. Anyone trying to store stuff really long-term and cannot afford degradation or loss needs to have a plan to update their archival copies every 15 years or at least do an assessment that often and survey the options as well as the physical and ideally logical state of their chosen back-ups.
