    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

      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.

      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!
