>> UNITEK 2 Port USB 3.0 PCI Express Card Review
Today for review I've got the Unitek 2 Port USB 3.0 PCI Express Card supplied by BrandoUSB. I took a look at one last week, it was a no-name or generic card and the speeds were decent, or at least they seemed that way as I didn't have anything to compare it to. In this review today I'll be comparing that no-name brand to the Unitek one I have today to see if there's any difference between a name brand card and a generic one.
