For imaging, just plug in a drive into a USB3 dock and copy your backup images there. Safer since you can keep it offsite, and same speed out of much less money than a 10 gbit networked solution (the drive(s) will be the bottleneck). Having an external SATA dock is also an option, I have one of those back panels with an eSata port and a molex to sata power cable port, so I can just plug in a drive directly without opening the case.
For media transfers, getting above 110 MByte/sec will be exciting for an entire day, after that you realize you just launch the transfer and minimize it and do something else while it is running and won't even notice when it finishes. I'm speaking from experience.
Game streaming wouldn't even push a 100mbit connection.
The rest would not benefit from higher speed networks since they all depend on your internet, which is capped to 1gbit everywhere but a handful places in the globe. From the top of my head there is one ISP in Finland, Spain and Romania, plus who knows how many in South Korea and Japan, where you can get 10gbit lines. Or are you telling me you have an internet line faster than 1gbit?
And if you have multiple systems with gen3/4/5 NVMe drives in RAID, and expect to have them interconnected through a local network so you can transfer stuff between them faster, then you already have a setup in far excess of what most consumers require. You also most likely spent so much money on it that spending an extra $400 on a 2.5gbit or 10gbit switch wouldn't put a dent on your budget. Or do you just want a 10 gbit line so you can watch the speeds go vroom vroom on iperf3 benchmarks? Why do you even have multiple gen3/4/5 NVMe RAID setups, what do you do on them, do you make money out of editing uncompressed 4k videos?
The fact that I do have a 10gbit home network. Trust me. It's overkill. If you would truly NEED one, you wouldn't be bitching about the enterprise prices on network equipment.
