<--pagebreak-->Testing

To thoroughly test the Vantec USB 3.0 to Dual Gigabit Ethernet adapter,  I will be testing network throughput between my main PC and another with similar specs on my home network. I will be using the TamoSoft Throughput Test Version 1.0 Build 28. During the test, the USB 3.0 cable from the adapter was connected to one of the rear USB 3.0 ports on my client machine. On this dual port adapter, I connected the ethernet cable to the closest jack to the USB cable. 

Client Testing Hardware 

All benchmarks were ran on my main system at home which features the following hardware. 

  • Motherboard: Gigabyte G1 Sniper 5 
  • Processor: Intel i7 4790k at stock clock speeds
  • RAM: 32GB Corsair Dominator Platinum at stock clock speeds
  • GPU: MSI Geforce GTX 970
  • OS SSD: SanDisk Extreme II 480GB
  • PSU: BeQuiet DarkPower Pro 1200W

Server Testing Hardware

  • Motherboard: Gigabyte GA-Z97X-UD5H
  • Processor: Intel i7 4790k at stock clock speeds
  • RAM: 32GB Corsair Vengeance at stock clock speeds
  • GPU: Gigabyte Geforce GTX 980
  • OS SSD: Corsair 480GB
  • PSU: BeQuiet DarkPower Pro 1000W

Additionally, I will be using the following hardware in testing. 

  • Switch: TRENDnet TEG-S80G 8-port Gigabit
  • Router: BUFFALO AirStation Extreme AC 1750 Gigabit Dual Band Wireless Router
  • Cabling: Cat 5e

You can see from the results above that the TCP upstream data averaged about 880Mbps while the downstream data was a little less at just over 650Mbps. These numbers are very close to what I expected to see based on previous gigabit Ethernet-based throughput testing, and are on par with the single port unit I previously tested. 

Again, while connected to my network over the USB 3.0 adapter, I took the liberty to do some real-world testing and loaded up a Google hangout with a friend, a skype call with the same friend and ran through a few rounds of Battlefield 4 and GTA Online. My ping was between 7ms -13ms slower on Battlefield 4, up to 48ms from an average of 30ms when wired into my motherboard’s Ethernet port. This time I also initiated a pair of fairly large file transfers from my PC to a NAS located in my workroom, and to my surprise, my Ping did not seem to suffer being only about 3ms slower than without the transfer. Just like the previous testing, I did not notice a difference at all in gameplay on either BF4 or GTA V.
