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 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.
