Aquantia AQC113 and Realtek RTL8127 are the two chipsets behind nearly every affordable 10GbE card sold in the UK. Here is the honest trade-off between them: driver maturity, heat and noise, and price, so you can pick the right one for your build.
How to connect a NAS and a PC directly over 10 gigabit Ethernet with no switch in between: static IPs, why you do not need a crossover cable, and how to point file shares at the right address on Windows, Linux, TrueNAS, and Unraid.
The three multi-gig Ethernet tiers compared honestly for UK builders: what each really costs end to end, which chipsets to look for (RTL8125B, AQC113, RTL8127), and when gigabit is still fine.
