I'm running a CalDigit Connect 10G on a relatively high-end NUC and it's great for a quick little Plex box that also sits on my 10G network segment next to a TrueNAS box doing 2x10G on DAC cables with LACP on a Chelsio T6225-CR.

I had bad luck with the QNAP QNA-T310G1S and Sonnet Solo 10G SFP+ (surprising as their stuff is usually rock-solid) -- both based on the AQC100S chipset and the aQuantia AQtion driver just didn't work for me under LTS Ubuntu.

I have a TS3, but it’s been hard to get a second or a TS4 lately.

So, this is really random, but if you can open up the case and figure out what is whining, folding up tinfoil neatly in half about a dozen times will make a really effective shield and cut like 95% of the whine. I found out about this trick from an open-source synth (PreenFM 2, incredible little frequency modulation synth) that had some whine due to the display. Sticking the thick piece of tinfoil between the display and the PCB boosted the SNR an almost unbelievable amount. Give it a shot, it only costs time and tinfoil! Be sure to stick some electrical tape around anything it might contact though, so you don't short anything out.

I've had my ts3 for a couple years now. I just noticed a pretty bad coil whine on mine lately. I'm not sure if it's always been there and my environment's changed or the device just suddenly started making the noise.

I usually can detect coil whines to an annoying degree, but I don't hear one in my TS3 Plus. Maybe your ears are more sensitive than mine!

Coil whine is about the only time having tinnitus works in my favor.

I have two 3x4k display Startech hubs, and one developed a very audible coil whine, the other did not. It was so bad it landed in a drawer.

Otherwise both worked fine allowing me to drive 3 screens on the OG M1 mbp. They each cost around 350 eur though.

That sounds like exactly the issue I've just described when I plug a USB C display into mine. I actually notice it, albeit to a much lesser degree, when I move a USB mouse connected to the dock.

Probably time for a change I guess.

I hear nothing from mine, but this may well be an example of me being 52.

The port arrangement on the front/back of that looks identical to the Kensington and Sonnet docks mentioned upthread, so I'd suspect that Razer are another vendor of a skinned reference design. (Though they're on the cheaper end of the spectrum so far, unless someone turns up the Aliexpress version.)

I have used the dock with windows and Linux machines and seen solar issues btw. So I would expect the same with an Intel mac

I have the TS3. It's been great BUT.... the Mac has not been great with it in the following ways.

(1) I keep my MBP closed. It take 10-30 seconds for it to wake up on keypress. That's so long that I often have no way to tell if it noticed I pressed key.

(2) If XCode is debugging and the screen sleeps then MacOS 12 never recovers unless I disconnect the cable, open the lid, get it wake up on the laptop monitor, and then plug it back in and finally close the lid.

I get why #2 is rare and therefore not fixed but still (T_T)
