alt Hacker News> It's wild to me that 10gbit isn't the norm by now
10G was too big of a step up from 1G. The expense and power required made it unattractive. Only recently have the interfaces for 10G over twisted pair become reasonably low power.
2.5G and even 5G are in a much better spot. It's where I recommend most people start as a default.

5G barely exists and mostly is the same price as 10Gb. 2.6Gb is taking off and mostly replacing 1Gb, but try to find a 5Gb switch, there really arent any, and most appear to be 10Gb switches with 5Gb PHY in them.
Yeah, 10GbE-over-copper switches are SO expensive. I bought a Ubiquiti enterprise switch for my home; 10Gb uplink and the copper ports are split between 2.5G and 1G. It's fine because only 1 or 2 clients can even talk 10G, and those are all across the house on Cat5 links anyway so they only negotiate to 2.5 even on a 10G port.
As much as I wanted to "future proof" by having a 24 port 10GbE switch... why? I'll just wait and buy one when I have a use for it.
