Focusing on performance, power efficiency, and cross-platform support, Plugable is pleased to announce the availability of our USB3-E1000 Gigabit Ethernet adapter!
A must have for any frequent traveler with a Apple MacBook or a Windows based UltraBook lacking a built-in Ethernet port, the USB3-E1000 is designed to fit easily in a travel case with no removable cable to lose. Having a wired network adapter can be a life-saver in conference rooms and hotels with marginal WiFi coverage. Being able to use a wired connection instead of a weak wireless connection in these scenarios can drastically improve speeds. The USB3-E1000 is also a great way to add a 2nd network connection to your Windows PC for sharing an internet connection to another device.
We tested the USB3-E1000 using the open source network testing tool iperf running on a Mac Mini 6,1 connected directly to a MacBook Air 5,1. If you’d like to duplicate our tests, and avoid the command line, there’s a nice pre-compiled GUI version available here: JPerf-2.0.2.dmg. In order to isolate the adapters as completely as possible, we connected directly between two Ethernet ports, set the IP addresses manually, and ran iperf as both server and client in each direction.
To maximize speeds, your entire network (including any routers or switches, and all cabling in-between) needs to be gigabit capable.
|Adapters used for this test||Client/Server speed|
|USB3-E1000 on Mac Air to USB3-E1000 on Mac Mini|
|USB3-E1000 on Mac Air to onboard gigabit Ethernet on Mac Mini|
These are low-level performance numbers (raw TCP/IP throughput). Real world throughput like copying a file over the network will be substantially lower due to transport overhead and any bottlenecks on the network or on either side of the transfer.
Using a tool like iperf and isolating the Ethernet adapters to a direct connection establishes a base line for data speeds. To further identify potential networking bottlenecks, introduce one network component at a time and rerun your tests to determine the delays and effect each layer of complexity has on your network.
Mobile users and power conscious consumers can rest assured they’re using minimal power thanks to the ASIX 88179′s energy saving feature set: auto cable length detection helps adjust power to accommodate for longer or shorter cable runs, IEEE 802.3az (Energy Efficient Ethernet) with lpi (low-power-idle) temporarily turns off the chip to conserve power, and IPv4/IPv6 packet Checksum Offload Engine (COE) support helps to reduce CPU load on the PC.
With backwards compatibility for older USB 2.0 and even USB 1.1 systems, this ASIX 88179 based adapter offers blistering performance on the latest USB 3.0 capable systems balanced with good cross platform support and backwards compatibility for older systems.
While Linux driver source code is available for Linux kernel versions 2.6 and later, compilation is required for all kernel versions before 3.3. This is a moderately complex operation not suitable for novice users.
This new USB 3.0 adapter will only work with Windows, Mac, and Linux for now. For other platforms like Android, Google’s Chrome OS, and for other devices like Tivo, Wii, etc., take a look at our Plugable USB 2.0 10/100 Adapter (ASIX AX88772 chipset), which supports many of these non-PC platforms with existing drivers already built-in to those platforms.
