To maximize network access speeds, select a USB Type-C SuperSpeed Gigabit network adapter if your computer has a USB Type-C port. USB 2.0 gigabit adapters are limited to maximum speeds of 480 Mbps by the USB 2.0 bus, while USB 3.0 bus allows the USB3-E1000 to realize the full potential of a Gigabit network, since it isn't limited by the USB bus speed. Testing in the Plugable lab using the iperf application on a local server have yielded speeds up to 890 Mbps. However real-world speeds around 400-600 Mbps are more realistic. When accessing sites on the internet, the bandwidth provided by your Internet service provider will likely determine your ultimate speeds.
