Fast as heck in team mode on Windows Server 2016

I ordered this card for my supermicro server running PVE v7.1. I did setup SR-IOV PCIE passthrough, and it is blazingly fast!

Works well

I purchased 2 of these. one to put in my desktop and the other to put in my truenas server. truenas core will not support this card. I had to update to truenas scale for it to recognize.

Easy setup - no issues

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.

This appeared in Windows 8.1/10 to be identical to the one on my motherboard

Good build quality. Meaty heat sink, female rj45 ports do not feel cheap. Did i mention fast?

Easy installation. Had to download software, but no problem there. I really noticed a difference in the smoothness and speed of internet. I had never used an Nec , but I'm glad I did.

Works. Dual NIC.

Generally available to consumers. Working fine with GBIC transceiver by Axiom, model E10GSFPSR-AX and multi mode fiber cable in Windows 2008 R2 with Intel driver version 17.0.200.2 on Supermicro X8DTU-F linked to HP switch.
