Review: Works fine for link aggregation at full speed - Despite what a previous reviewer stated, this device works just fine for link aggregation at near full speed. Link aggregation works by apportioning traffic to multiple destinations to different ports of the aggregated link based on a hash of the destination MAC and IP addresses, so traffic to two destinations could each use a different port and get the full speed of that port. It provides no throughput benefit for a single destination host. To properly test throughput over all ports of the aggregated link, you need to send traffic to two or more destination addresses at the same time. I ran such a test using iperf3 to two destinations with consecutive IP addresses (10.0.1.90, 10.0.1.91), but it still used only one port according to traffic counters on my switch, resulting in only about 460Mbps throughput to each host. When I changed the destination host's address from .91 to .92, this resulted in test traffic going via separate ports and I got close to full speed through both ports simultaneously: 110 MB/sec or 920Mbits/sec. Link aggregation was working as expected. The USB3 gigabit chips used in this adapter are ASIX AX88179, which are well supported by Linux. Whether using link aggregation or not, this is a useful adapter to have.
Review: Great product, full USB 3 - Great product, full USB 3.0 speed through hub and included power adapter means that I know I won't draw too much current for one port. FYI, it does work quite happily as a hub and with ethernet functionality without the power supply but I've not tried this with much data throughput. Powered, the ethernet port is fast enough to (almost) saturate a gigabit connection (~110MB/sec) but I am almost certain this is due to overheads, cable length and other networking variables which are of no fault of the hub.
