In Network Interface Cards

I was instantly able to take advantage of my new 2000mbps internet service.

Installed easy, no driver download needed. Had issue with MOBO adapter not providing the speed the PC should have been getting. After installing this device speed was right where it should be.

Plug and play!

I plugged it in. It worked with existing cabling. I cant argue with that.

it works with Windows 10, it won't be the bottleneck at either the bus or the switch, so you can focus on troubleshooting other things, it's tiny yet solid and fits in a very tight x1 slot.

- Intel card works with every device NIC I have with no issues - Worked at 1, 2.5 and 10GB for me with no issues - two ports - Can team depending on the OS

They work great.

Windows 10 Pro support VLANS Jumbo Frames More ports than i could ever use.

Windows 8 seamlessly installs the driver for this product. Works great on my Thinkpad X1 Carbon with Win8.

Works with the "UF-MM-10G Multi-Mode Fiber, 10 Gbps SFP+" and the Ubiquiti switch. 10x faster than 1G. Works with linux.

Extremely pleased with these, but I did my homework before purchasing. They compose a VMware vSphere 5 storage network. 2x Dell 8024F switches 5x Dell R710s with one of these cards in each server (ESXi 5 hosts) 1x Dell c2100 Server running NFS off of Nexenta CE 3.1.3 with 2 of these cards in it (one PCI based as sold here and another that is a mezzanine card) for an aggregate 40Gbps throughput to/from the SAN. tons of Cisco SFP-H10GB-CU3M/SFP-H10GB-CU1M cables used for connectivity. These were chosen for compatibility/reliability as we planned to build our own SAN solution after pricing every storage vendor we could fathom. We ended up spending a fraction of the quotes we were offered and got more for our $. Shipping as always was remarkably fast w/ NewEgg.

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.

Dual network ports over RJ45. Backwards compatible with FE and GE (100Mbps and 1Gbps) Comes with standard and low profile brackets No drivers needed for VM Ware ESXi (5.5.0 u2 tested), Citrix XenServer (7.2 and 7.3 tested)

Works with both PFSense and Proxmox without any special configurations.
