I think the really important distinction here is Burnable BD-R discs, not BluRay movies as a whole.Sony has shut down all production of recordable Blu Ray media, including mini disc and miniDV cacassettes.
Entirely false for anyone that cares about quality. Admittedly it's not a large part of the market anymore, as most have switched to lazy screen + soundbar and nothing else. For we audiophiles and cinephiles, having full quality 4K discs for our full surround sound setups with larger (and huge) displays will remain very important to us for a long, long time.Streaming has won. Even with the lower bitrate, because people dont really care.
I don't think it really did. The multi-layer capacity limit of BDs is what 100GB I think? IIRC cost ramps up quickly from the standard 25GB blu ray and they don't preserve any better than DVDs (with the same X years under ideal conditions etc).
I would assume the write speed for backing up data that large would be pretty dismal too, but I'm entirely speculating.
Never burned a 100gb disc, but yeah even a 50gb disc took a Looooong time to burn. But it was family stuff, important documents and scans. It's in my family's safety deposit box now I think.
Probably have only ever burned 4 or 5 BD-R discs total, ever. So yeah, I can see why it was shut down. IMO, it really was the burning speeds that killed it off for good, as no one even wants to leave a laptop on for the time it'll take to burn a 50 or 100gb disc.
Maybe we'll have a new slowish -speed SSD that's designed for longevity and durability soon? I wouldn't put a current USB key in that safety deposit box and trust it to absolutely never have a problem, even if current tech is a 99.9% guarantee.
