Great for a FreeNAS build with a legacy logic board

My Haswell era logic board, which is used for a FreeNAS build, has a flaky on-board Realtek LAN chip. The board\'s two PCI-e slots are filled with SATA controller cards, leaving only two regular PCI slots free. I bought this Intel PCI network adapter to fix the networking problems I\'ve been having. FreeNAS dashboard reports 95MiB/sec, which is great, and the same as the performance of the Intel PCI-e cards on another system I have. I\'ve transferred about a terabyte of data over it so far without any problems.


Dated but still quite usable NIC

Bought this card 10yrs ago, but never used it as I later bought the “CT” version and installed using a spare PCI-e expansion connector in my old Win 7 eMachine desktop. Well, I now need two PCI-e slots for video and eSATA cards, and having a spare PCI slot available, I dropped in the PRO/1000 GT card...after booting up, Windows immediately recognized the device, automatically provided the driver and 30sec later was on-line. Did an Ookla SpeedTest, and got nearly 500Mbts/sec download, identical to the CT version, so all is well. As other customers have noted, this device has only “in-box” support now, so the only drivers available are assigned by Windows -and they are over 10 yrs old - as this is a legacy NIC. Yes, very much an old-school Ethernet adapter, but it delivers the goods, so who’s complaining.


A little more expensive but decently fast

Getting promised speeds and has lasted since I purchased it.


1K speeds. Plug-and-play

1K speeds. Plug-and-play. Windows will find drivers.


This worked perfect for my Windows 10 PC

This worked perfect for my Windows 10 PC. I had to return it cause I discovered the issue was not the NIC on my PC but the actual Spectrum ports on my router.
