It uses Thunderbolt 3 protocol, which is not supported by the RPi4. Why not the 10 GE Thunderbolt 3 Sabrent TH-S3EA? Although it has a USB-C connector, it is not a USB adapter.

Why not use the cheaper 2.5 GE USB 3.0 Sabrent NT-S25G? Because it uses Realtek 8156 chipset, and there is no suitable Linux driver available at the time of writing. It came out as a clear winner: Credit and kudos to ServeTheHome ServeTheHome team did a great job of comparing the 5 GE adapters using the same chipset as the 5 GE USB 3.1 Sabrent NT-SS5G.

It ships with USB-C and USB-A cables so you can connect it to your laptop using USB-C or RPi4 using USB-A.

If you can enable 9000-byte Jumbo frames on all devices involved in the data path, the upload speed becomes much healthier. Upload (from a client to RPi4 server): 528 Mbps.Download (from RPi4 server to a client): 2.05 Gbps.These were 90-second iperf3 tests with standard 1500-byte MTU and a single iperf3 stream. The maximum TCP throughput Raspberry Pi 4 iperf3 server can handle with a 5 Gbps USB 3.0 Ethernet adapter. At the time of writing, Linux kernel 5.10 is the Raspberry Pi OS gold standard, and that’s what I used for all tests. I researched USB 3.0 multigigabit NBASE-T Ethernet adapters, and purchased a few. So, the question is, can it support multigigabit speeds?Īlthough it does not have any PCI Express slot available, it does have a couple of USB 3.0 ports. Raspberry Pi 4 (RPi4) is widely available, and there is a chance that you might already own one. While the standard 1 Gbps adapters push around 950 Mbps of TCP traffic, the iperf3 server will sooner or later become a bottleneck for throughput measurements. With the first consumer Wi-Fi 6E routers already shipping, and enterprise access points being worked on, I think it is now time to up my iperf3 game.
