Ethernet will usually hit hardware limits of your HDD or SSD before it actually maxes out. 1gb ethernet is better than wifi in 99% of cases because wifi in the real world is pretty bad, even with modern standards. Why else do they have to continually revamp the standards to get around congestion and roaming issues? Cuz wifi is garbage in the real world. Ethernet = Very little jitter, latency, or packet loss. Wifi = Tons of jitter, latency and packet loss.
Your take is really weird and doesn't represent the real world. What blog did you read this on and why haven't you bothered to attack that obviously wrong stance?
This is the most ridiculous lie in the thread. An ethernet link that can barely keep up with a $150 SSD costs $1250 per switch port, and needs a $1200 NIC and can go only 3m over copper before you need a $1000+ optic assembly. There is nobody with an ethernet setup in their home that outruns consumer-grade SSDs. "Ethernet is limited by SSDs" is a Charlie's Hoes level of wrong.
But if you actually want your Ethernet to be similar speed to your SSD, you don't need to spend that much. Get some used gear.
32 port 40GbE switch (Dell S6000) $210 used
Dual port 40GbE NIC (Mellanox MCX354A-FCCT) $31 used
40GbE DAC 1 meter new price $22
or 40GbE optics from FS.com (QSFP-SR4-40G) $43 new + MMF fiber cable
Of course, that's probably not going to be very power efficient for home use - 32 port switch and probably only connecting a handful of devices at most.
