Review on 🔌 X-MEDIA 4-Port USB 3.0 PCI Express PCIe Controller Card, USB 3.0 Expansion Card [XM-UB3204] by Brian Olson

Overall this is a good card and I connected an external power supply. But 2 times in the last month the card didn't work at all. Both times I had cold boots that had nothing to do with sleeping habits or sleep problems. I am using W7 Pro x64. I had to open the case and reinstall the card to get it working. I don't know why, I don't touch my case and the cards inside. Really good read/write speeds and I can use the external hard drive dock along with HDTUNE to see full SMART status. Something that some external enclosures and USB 3 cards don't report.
