Pros: I bought this card to replace the defective internal network card from my Acer H340. Replaced with the slim format attachment easily and transfer speeds were faster than the internal card.

Cons: None

Pros: Does everything a gigabit NIC SHOULD do, and it does it well. PLUS, make sure you get the latest drivers from Intel, because, WOW, configuration properties are now the way you always wished they could be. Every advanced option described in detail, click links for more information, link integrity detection, cable length and quality detection, VLANs, Boot options, Teaming, you truly have to see it to believe it. I have never been so happy in my life for spending the little extra coin on this adapter vs others. It will install just fine first boot with windows drivers, but get the latest from Intel and I promise, you will spend a good hour+ just looking over the device manager properties alone from all the options and education you can give yourself by going through it. Oh, and the NIC performs just as amazing as the options sound. It has out performed 2 other gigabit PCI-E 1x NICs I own, a PCI-E on board gigabit, an Intel PCI-X Gigabit, and obviously PCI gigabit NICs.

Cons: NONE

Other Thoughts: Other than server level nics and the uber expensive 10gbps NICs, I don't know of any which can out perform, ESPECIALLY for this price.

Pros: Works with ESXi 5 - seen immediatly - no driver install needed.

Cons: None

Other Thoughts: Great for the price!

Pros: Its an Intel NIC. that is a pro in itself. NICs are one area Intel does well. Most recent purchase is specifically for its chipset as I'm using it in a custom network appliance. This is my second time purchasing this model.

Cons: None

Pros: none

Cons: didn't fit in the PCI slot, front tab was cut incorrectly, went in the trash.

Pros: Quick low latency nic. I get 90-100 MB/s copying from a network drive to one HDD, and 120-130 MB/s (though I think windows was estimating wrong since it was 130 MB/s+ sometimes, and max theoretical is only 125 MB/s) copying to another one. I also get fewer lags and pauses while browsing the network share now too. Plug and play in Ubuntu.

Cons: Its not free? Shipping took about a week but oh well.

Other Thoughts: Put it in a old Celeron 3 GHz machine that only had a 10/100 mbps integrated nic. Runs Ubuntu Server 10.04 and primarily used as a Samba file server.

Pros: I have quite a few of these, including four in a single PC. No problems.

Cons: None so far.

Other Thoughts: For a faster boot time I use Intel's bootutil.exe to turn off PXE booting.

Pros: I've now bought at least 3 of these cards. Intels are the best nic adapters. Throughput and just as importantly, latency are much better than cheaper nic adapters.

Cons: Does not do vlan tagging. Have to move up to intel server nic adapters to get vlan tagging

Other Thoughts: Worth 2x the cost of cheaper adapters

Pros: Bought and installed as cheap 1gb card to server as internal network interface in computer built as Untangle Router.

Untangle recognized the card during install without drama.

Cons: -

Other Thoughts: -

Pros: My gigabit network performance was a pretty solid 20 MB / sec accessing my NAS using a Jumbo frame of 9000. I have a manged switch that can support a 9000 byte jumbo frame - many can't.

With this card I get 59 MB /sec just by setting the jumbo frame through device manager and nothing else other than default. I was using the built in MBoard gigabit nic before under Win 7 64 bit. It was at least solid but this performance is much better.

Cons: Win 7 installed default driver automagically on reboot after install. I had the drivers from Intel in a folder and just ran it and it will add the new drivers. No reboot required. It's not a con but if Msoft had the right drivers it wouldn't be required. Go to Intel and get the drivers from them!

Other Thoughts: For the cheap price I paid, my in house NAS performance tripled!
