USB 3.0 Super Speed PCI Express Card installed easily into my computer (Vista) and worked perfectly. I use it for my backup drives and noticed a speed improvement well worth the price. 13GB file xfer with USB 3.0 takes me 3.0 minutes, with USB 2.0 it takes 8.0 minutes. That's 2.7 times faster, or 22 minutes vs. 60 minutes. I like it.
