Works right out of the box in Windows 11. Installed it, booted into Windows, did a restart as it didn't seem to connect right away and worked fine on the second boot. Speeds are great. Finally getting my full 2Gbps fiber internet. Over 2.2Gbps down and around 2Gbps up. Cheap price and free shipping as well for something I didn't realize I needed.

Used this to expand the number of drives in a smallish Ubuntu home server. Still testing, but seems flawless so far and transparent to the user - just more drives available. All I did was power down, plug it in the PCIe 3.0 slot, attach a couple drives, and power up. Drives were recognized immediately and accessible like all the others. They claim max throughput of 277MB/s but so far both drives tested at 500 MB/s+ the same as when plugged into the mobo ports. I assume the limited speed might occur if multiple drives were accessed at once. Since it's a server and I'm using this to add SSDs, i doubt I will ever notice any slow downs. Bonus: the 6 provided SATA cables have locking connectors and are of a reasonable length.

I was a little worried that I wouldn't be able to install the correct drivers as I don't have a disc drive on this pc. but windows was able to get it done without me doing anything.

Even on an older motherboard it was still detected.

Bought it specifically to run multiple Kinect2s on one PC with libfreenect2 under Windows. Works perfectly, all four K2s run at 30fps. Works under Win7 x64, Win8.1 x64, and Win10 x64 plug-and-play. I think the bad reviews about compatibility are older and those issues have been fixed.

I needed a PCIE usb card with a Renesas USB controller for my Nvidia 3D Vision emitter. Im on a z570, which introduces some timing related issues that cause the emitters timing to drift. The only way I found to fix it, was to get a Startech PCIE usb card with a NEC or Renesas controller. Startech was the only brand with reasonably priced options, although, even this two port card was more than I wanted to spend. It works though, I spent days trying to find a solution to that problem after upgrading from a z370 to a z570. I think the listing says its NEC, but windows shows it as Renesas, it doesnt matter because either will work.
