Does this have anything to do with transistors and computation? Or are they only talking about harddrives? A huge increase in density would be cool, but I’m not really convinced they would get much faster because most of the slowness comes from physically moving a reader arm and lining it up with insane accuracy. It may be able to complete with an SSD for density, but speed is debatable.
Yeah, for movies and TV shows in original quality, physical media makes a lot of sense due to the size. I know I’ve been able to buy lossless music as raw FLAC file downloads, which has been really nice.
