Man, I've had two separate devices fail to install updates the last week, leading to tons of weirdness and troubleshooting. I even had to chkdsk c: /F at one point like a neanderthal.
I have enough coomputers laying around that I'd move more of them to other OSs, Linux included if I hadn't tried that and found it as much or more of a hassle in those specific machines, be it compatibility issues or just fitness for the application. I'm not married to Windows at all, but there are definitely things that are much easier to handle there, which does justify sticking with it through the reinstalls and awkward weirdness on those.
I rip enough physical media to tell you that post-compression 14GB is not far from average for a 4K movie. I guarantee that Netflix isn't storing those any bigger than that. Hard drives don't grow on trees, you know?
It's still good to know where the top end of optical storage is, even at an academic level, even if these end up not being widely used or being used for specific applications at smaller capacities. We'll see where or if they resurface next, but I'm pretty sure we're not gonna get femtosecond lasers built into our laptops anytime soon.
