I don't mean to nitpick, but absolute values for both of these matter much less than how much it is compared to "enough". As long as the throughput is enough to prevent the video from stuttering, it doesn't matter if the data is moved to your video player program at 1 GB/s or 1 TB/s. Conversely, you say you don't mind if a video buffers for a moment but I'm willing to bet there's some value of "a moment" where it becomes "too long". Nobody is willing to wait an hour buffering before their video starts.

The perception of speed in using a computer is almost entirely latency driven these days. Compare using `rg` or `git` vs loading up your banking website.
