Within a few minutes, this is working without issue. Unlike the TRENDnet solution, the Marvell downloadable driver installation package does not trigger Microsoft Defender SmartScreen. 5GbE Marvell Aquantia AQC111U Adapter Drivers Marvell acquired Aquantia but we still have an Aquantia branded installer here.

We were able to download and have the new Marvell drivers work out of the box. Startech 5GbE Adapter Driver Zip Upon Insertion In either case, the drivers become out-of-date and one can get newer 1.8.0.0 (as of this writing) drivers from Marvell. Our security-minded readers may cringe a bit at this solution. On one hand, this can be very useful if this is your only Internet connection. Indeed, inserting the NIC has an auto-mounting (in Windows 10) storage solution that has 32/64-bit drivers. This means it utilizes the Aquantia AQtion drivers and our test systems did not work out of the box. The NIC uses the Aquantia AQC111U which is now a Marvell offering. In Windows 10, the USG5GA30 is not as simple to set up as the Realtek based 2.5GbE USB 3 adapters. StarTech USB to 5GbE Network Adapter Setup Overall, this is a very simple unit from a hardware standpoint, so let us get to the hardware. Startech US5GA30 USB To 5GbE NIC Air Holes Cooling is a concern with the TRENDnet unit which is why we mention it here. Still for whatever reason, this unit, so long as it is sitting out free of excessive ambient heat or airflow restrictions, has enough cooling. The unit gets warm even with these vents. The top of the unit has holes to vent heat. Startech US5GA30 USB To 5GbE NIC USB Type A That is significant since it limits the overall USB speed to 5Gbps for our 5Gbps NIC. We see this as a USB 3.0/ 3.1 Gen1 device, not a Gen2 device. We will note that StarTech, like other vendors in this segment, does not specify the USB generation.

There are plenty of Type-A connectors on modern systems so this is fine for most use cases. Sabrent’s solution which will be the next review in this series, allows one to pick a cable for Type-A or Type-C. The TRENDnet TUC-ET5G uses a Type-C connection.


We are going to see why one needs to take that in context in our performance section. This port announces that it can link at 5 Gb/s. On one side of the unit, we get an RJ45 port. The StarTech USB to 5GbE adapter we are reviewing is technically the US5GA30 model. You can check out a summary of the three options we tested in that video. Update: Since we have this series, we made a video talking about the three units and what we saw when testing: This is a relatively simple device that one can use to easily add a 5Gbase-T networking port to most systems. For this edition, we have the StarTech USB to 5GbE adapter review. We are now in the middle of our USB to 5GbE adapter review series.
