This USB to NIC works pretty well. It installed very easily and I've had no problem with it. My NIC port on my laptop was a little loose and was intermittent if I didn't watch the connection closely. This was a quick and easy fix for me to get a few more years from my laptop. I work with megapixel video cameras (sometimes up to 30+ at once) and it appears to handle that type of traffic just fine (probably better than my processor).

The obvious question is why one would purchase this card over the far cheaper options. Generic 1Gbps NICs can be had for just over a tenth the cost, while Intel's desktop varieties run less than half the price of this card. Leaving aside the cheapest cards - ones I've found to cause more problems with data corruption and reliability than it's worth - the main reason to go with a server card is if you will be loading it heavily. If you're running your own datacenter, power-saving features such as EEE and DMA coalescing are handy, but that likely doesn't apply to most potential customers for this NIC. The I210T1 does an even better job at offloading calculations than previous generation NICs.Saturate a full 1Gbps connection with multiple streams and you'll see CPU usage drop in comparison to what it is with desktop cards. We put this card in a workstation to replace the on-board Realtek NIC. System CPU time dropped by 20-30% under very heavy network loads after switching to the I210T1. Another benefit to the I210T1 - and a possible reason to upgrade to this new model - is Audio Video Bridging (AVB) support. When working on projects where multiple media streams need to be perfectly synchronized, AVB worked wonders. Older NICs simply could not keep everything synced perfectly. We needed to work on 10Gbps connections instead. Being able to accomplish the same feat with a much cheaper card is great! The I210T1 is tiny. It fits easily even in systems with bulging heatsinks and video cards.

Easy installation, fast, cheapest solution for 10G.

Easy to install, just make sure your board supports it and that you don't have any other PCIe x4 devices requiring resources, if you do this card will downgrade itself to PCIe x1 and you will only see about 3gbit a second transfer rate, which for most people is more than enough.
