What? I see, where do we do we find a similar speed switch. And NICs for other computers.

309 isn't a such a "massive price" intel X550-T1/T2 10gbit ethernet NICs are around 220€ yes there are cheaper but not as good in my experience Aquantia gave me several problems over the years and it's never breaking speed record be it of amd threadripper, intel z390 onboard or in one of the asus aqc107 nics (own one) fyi I get noticeably better speeds using amd x570+intel x550 nic than with a z390+onboard aqc107 I'm suspecting the "no lanes" Intel "gaming" chipset/cpu z390 (16x pcie 3.0 lanes) didn't have enough bandwith to handle 10Gbit because before it I had an X99 motherboard + i7 5960x (40x pcie 3.0 lanes) and got better speeds on it too just like now on amd X570 apparently I'm eligible for 25Gbit optic fiber lol now like anticupidon says, I only have 10Gbit computers to connect it to and frankly I don'see any use for it 10Gbit is already extreme, you're limited by the drives the motherboards etc...connecting to it a quick search gave me super expensive cables but no "consumer level" switches or NICs..too soon, maybe one day I'll switch "for science" 😀

Actually 25 Gbps stuff isn't anymore that expensive (in an enterprise view). SFP28: https://www.flexoptix.net/en/sfp28-sr-transceiver-25-gigabit-mm-850nm-100m-1db-ddm-dom.html?co8600=81150 Switch: https://www.router-switch.com/n9k-c93180yc-ex.html Or https://itprice.com/cisco/c9300-24t-e.html plus https://itprice.com/cisco/c9300-nm-2y.html Yes I'm not willing to spend this much for home use, but for smaller enterprise this might be interesting. Also a local (Swiss) ISP recently launched their 25 Gbps internet offering, with this router: https://mikrotik.com/product/ccr2004_1g_12s_2xs#fndtn-specifications (costs about 700 USD with two 25 Gbps interfaces)

Wow, Mikrotik is on high tide. Will take some courses or certified classes. Amazing what a small company can achieve.
