A Closer Look
“Vantec introduces the USB 3.0 To Dual Gigabit Ethernet Network Adapter bringing you Dual Gigabit Ethernet through a single USB port. With the ease through a single USB connection, you can gain gigabit network speeds of up to 1000Mbps and be connected to two separate physical networks for any special function like network management, networked virtual machine configuration, bridging, gateway management, networking troubleshooting and more. This is a convenient solution for any IT administrators to bring along with their systems such as laptops, Ultrabooks or Macbook Airs to analyze and manage any networks. This USB 3.0 To Dual Gigabit Ethernet Network Adapter comes with a wealth of features to help enhance its use.”
The Vantec USB 3.0 to Gigabit Ethernet Adapter is comprised of a plastic enclosure with a highly polished top plate. I actually prefer the brushed aluminum top plate of the single Ethernet jack adapter better, and would prefer it on this dual version as it’s intended for a more professional environment.
Here you can see the dual gigabit Ethernet jacks along with a seven-inch USB 3.0 cable.
Looking at the back of the adapter, we can see a sticker containing the MAC addresses for each ethernet port.
Just like the CB-U300GNA USB 3.0 to Gigabit Ethernet adapter, the CB-U320GNA USB 3.0 to Dual Gigabit adapter is quite small, and its construction feels very high-quality despite its plastic housing. The USB cable is not too long nor too short, and it is thick enough that you do not have to worry about it hanging off the side of your laptop. Now that we have seen the adapter from every angle, let’s move into some throughput testing.
