The card works perfectly placed for me in the back of my pc which dates from 2010 WIN7 64 bit, rapid 3.0 ports and the quality of this card is felt immediately.
Works perfectly with 2 self-powered hard drives connected simultaneously (3.0 TOSHIBA AND VERBATIM 3.0) (and all my other usb stick of different brands). Much faster (x2x3 with large and small files) than 2.0. Even with USB 2.0 key nickel and it works faster than a 2.0.
Devices Tested with 4 works perfectly.
