More devices used at once? If I am downloading 1 Gb/s from the internet, and meanwhile one of my housemates want to look at a movie from our NAS, the other one wants to backup 100 GB of photos to the same NAS - then 1 Gb/s home network is not enough.
Your 1G switch should be able to do 1g from your computer to your internet router and 1G from your roomate to the NAS and whatever from your NAS to the guy watching movies. Even cheap gigabit switches can process (large packets) at line rate on all the ports. If your NAS is also your internet router, maybe you can't make it work with a 1G switch, unless it can do link aggregation.
I'm not arguing against faster networks, but scenarios like "one fast download makes video streams buffer" can be solved by using better routing algorithms (CAKE for example) instead of making the pipe so wide that it'll never be close to full. One of these is a configuration flag that you can flip today and costs nothing, the other means upgrading infrastructure.
I am confused, as the link appears to say the opposite.
> Conclusion:
>The majority of 4K movies (75%) I tested have bitrates over 100 Mbps and many seconds where bitrates spiked over 100 Mbps. Some have 100s of seconds where bitrate spikes over 100 Mbps, and will most certainly cause problems if played with bandwidths less than 100 Mbps on devices that don't buffer well such as the LG TV or Roku TV. To make sure you get the best experience without any buffering or transcoding on such devices, you need to make sure you have a bandwidth that exceeds at least 150 Mbps to play most 4K movies properly. Ideally, it should be higher than 200 Mbps.
The highest average bandwidth shown was 73 mbps. You probably need 150mbps to comfortably play 1 4k move, but once you are looking at the effect 4k movies have on higher bandwidths, average bandwidth becomes more relevant. You could pretty easily stream 10 4k movies over a 1gbps channel since the odds that all of them will be over 100mbps at the same time is low (and even if it happens briefly, it will be handled by buffering).

"If" is doing some heavy lifting there.
The linked post shows that the average bitrate of every sampled 4k movie was less than 75 Mbps. The author even bolded "on devices that don't buffer well such as the LG TV or Roku TV"
I have Jellyfin setup and there are times when 3ppl would watch something. My entire collection is the highest quality I can find on the net so normally a movie would be around 80-100GB.
Plus I have a service which downloads stuff for the archive team so that’s always doing some network traffic.
There is also a CI gitlab worker and that is also always doing some build with docker images from scratch.
I just wish more than 1Gbps was something that was offered and I can upgrade but so far I’m limited by my ISP with no way to upgrade. Inside my network I have 10Gbps and I have never hit that limit. It was expensive and I needed it for a now deprecated servicing.
Doesn't matter when the entire network bandwidth is taken by my 1 Gb/s download and/or the photo backup. Everything on top of that needs too much bandwidth then.
1 Gb/s network is probably enough for most people, I agree. But I certainly think there are many use cases for faster networks, especially in digital-heavy households.
