ORICO PVU3-2O2I PCI-e card with 2 ports USB3.0 external and internal 20pin USB3.0

1. To install: without proprietary drivers the part not running under Windows (in my Windows 7/64 bit).
After all, is my operating system (in the Device Manager via "driver update") the driver on the CD automatically beiliegenen.
The card is supplied with a low profile mounting plate; that is to be commended - unfortunately sits the power jack
directly at the top edge of the card; the power connector will no longer fit in the computer case
(In my Fujitsu Esprimo E5730). Solution: Power plug about 5 mm Carefully saw off the remaining webs between
pinch back the power cables and the power cable bend 90 °; fix the whole with Araldite and isolate.
With intelligent arrangement of the power connector, the manufacturer could have spared me this work (about 1 hour).
Besides asked to see the dealer selling this stuff, the goods to advance?

2. In order to function, I have tested the software "ChrystalDiskMark" and a 1TB Toshiba USB3 hard disk data transfer rate.
The differences are considerable USB2: threefold speed "Sequential Read / Write test (block size = 1024KB)" and
60% speedup with "Random Read / Write Test (Block Size = 512KB)".
More could not ask because both the hard drive as well as my PCIe 4X interface limit the data transfer rate.

3. Decision: The card does - after appropriate use of the user - what they should.
Nevertheless, because of installation problems two star deduction.
