Sabrent Thunderbolt 3 to 10 Gbps RJ-45 Ethernet Adapter (TH-S3EA)

works great - only thing it does get quite warm though

When first shopping for a 10GbE Ethernet adapter for Thunderbolt, I was surprised at both the lack of choices and the large amount of critical reviews. I decided to pick one of the less expensive devices (almost at random) to try it out...First of all, this is NOT a USB device. Despite the fact that it plugs in via a USB-C connector, it doesn't "speak" USB. It uses Thunderbolt. If your machine doesn't explicitly support (and have enabled) Thunderbolt 3 or 4, this device won't work for you.Second, this device can't magically make your network go faster. If this is plugged into a switch that's slower than 10GbE, it will only negotiate a speed up to the capability of that switch. If the ethernet wiring is poor, it might even negotiate a SLOWER speed.Finally, this device WILL get hot. That's just the penalty of using 10GbE RG45 devices. Don't want the heat? Find another adapter that uses an SFP+ connector and use either fiber or a DAC (direct attached copper) cable to another SFP+ jack.All that being said, the device worked perfectly on both an M2 Macbook Air, and on a mini PC running linux (debian 12) without having to install special drivers. The linux box did require enabling thunderbolt and a reboot. I haven't been able to test this under Windows, though it should work fine with Marvell ACQ107 drivers.Once properly installed (with proper CAT6 or better cables), this device maintained full 10 gigabit transfers to other 10 GbE devices both directly connected and via a 10G switch. It full supports jumbo frames (at least up to 9000), VLANs, etc. It's been reliable enough that it's become the "permanent" network device on my proxmox server (running on a mini PC.)

Was exactly as described

I use this for my NEWS server 10G internet connection and get 575MB/sec downloading 80GB files. I was using the OWC but we identified a problem with it when you start to run over 50 connections to the server, after hours of trouble shooting with a very knowledgeable tech, we identified the one difference between them, the Intel TB3 chipset. The OWC uses a higher end version of the chipset that supports video and this one uses one below it, but it only for networking, so none of the other things the OWC had in it. Also you need to set your TCP Receive and Send Buffers to the max in the driver details of the device manager.This thing is rock solid, but it get hot, around 48° Celsius, always, so keep it in an open area and have a good insulater below it, mine is on my glass TV stand beside the server.The OWC's are great, but not for what I was looking for, this one I just decided to try and it had zero issues.Highly recommended!!

Fantástico funcionamiento.La temperatura aumenta cuando lo usas un rato, lo normal dadas las prestaciones.
