For a moment I thought about setting up 10GbE at home, but then I realized there is no point yet because my external connection to internet is limited to 1 gigabit.
The only use internally would be central storage server. But all the new NVMe SSD's are faster than 10 gigs, so my internal network would be the bottleneck.
The next logical step would be upgrading to 100 gig network, but that is too expensive right now. I should buy more fast NVMe storage for that money.
If I could get 10 gigabit connection to internet, it would probably make more sense, but I don't see it coming that soon. And I'm paying 15€ for 1 gigabit right now, I would not be willing to pay much more for 10 gigabit connection.
On top of that, my Zabbix monitoring data shows that I rarely saturate the 1 gigabit connection to internet. Most of the time I don't need more than 10 megabits.
