StarTech.com 4 Port PCI Express PCIe Gigabit Ethernet NIC Network Adapter Card (ST1000SPEX42)

Item was received as advertised. No issues to speak of at this time with the unit. Will look to this Vendor for future requirements.

does what its supposed to do. allowed me to provide redundancy and higher performance on a NAS server.

This works fine in my Linux system -- CentOS 6.5.

Excellent service, excellent product.

Great card.Took me a while to get the LACP working under Windows7. Instructions shipped not that great for it, and nothing new about realtek teaming app since 2012 on the net.Here's how I managed it.1. Install the device in the PC/Server and power on.2. Went to device manager and uninstalled the drivers for it.3. Search for 'realtek teaming utility windows 7' on Google, I used a link from Arvind Gaba's Technology Blog called RealtekTeamingUtility_V2_0_0_5_Win_3264bit - it dates back to 2009, but do not fear.4. It installs as a diagnostics utility, but that utility allow teaming to be configured.5. In device manager, right click on a realtek NIC interface, and get windows to update the driver. Do the same for the teaming driver.6. In the diagnostics utility, configure a team and add the adapaters you want.Good luck.
