Define expensive? 10GbaseT is not that much anymore. Also a number of vendors are supporting 2.5/5G speeds. Ubiquity has some reasonable kit. I am planning on dropping a 10G into my FreeNAS box and getting a thunderbolt 10G for my MacBook. The idea that the 10GT PHY can work in an adapter is pretty cool. Back in the day I worked at a startup that did one of the first 48x10GT switches and the PHY was 5 watts each x 48. Sorting the cooling was fun. As DC switch the noise was fine, but working with the prototypes at your desk or in the lab was quite loud.

For switches of around 8 ports, 1GbE is about $2-3 per port. 10GbE over copper is about $70 per port, way higher than justified by the bandwidth increase alone. 10GbE is getting cheaper, sure, but it definitely isn't cheap yet. A 10GbE switch is still more expensive than all the equipment required for a 1GbE+WiFi home network.

  I just did some research: this switch doesn't seem bad, or am I overlooking something? https://www.fs.com/de-en/products/72944.html?gclid=CjwKCAjwtqj2BRBYEiwAqfzur7FInqXvr0G5hxrv9s3t9EAW14KSfbvouEUEYlBIKht34zvVaLXrCxoCGrkQAvD_BwE https://www.fs.com/de-en/products/72944.html?gclid=CjwKCAjwt... Fanless, 24 normal ports, 4 10GbE ports. What do they mean when they write "...with 4 10Gb SFP+ Uplinks"? Are they meant only to aggregate the traffic that comes from the 1GbE-ports or can they be used as well to exchange traffic between 4 servers, each one using 10GbE?

    That switch should be able to do regular switching between its four 10Gb ports, but first you need to buy SFP+ transceivers to plug into those ports. 10G Fiber transceivers start around $20 per port, but 10G transceivers with RJ-45 ports for ordinary twisted-pair copper cabling are $40-70 per port. So to get that switch equipped to actually do 10Gb switching over copper would drive the price per port over $100.
