[dba-Tech] USB 3

I am going to add one or more external hard drives to one of my machines.
I wanted to use the fastest tech possible.
I added a "USB 3" card to this machine.
Purchased from Amazon:
AnkerR Uspeed USB 3.0 PCI-E Express Card with 4 USB 3.0 Ports and 5V 4-Pin
Power Connector for Desktops [VL805 Chipset]
by Anker 

It installed and works but with a message saying that it is only running usb
2.
I am still researching external drives and not ready to buy yet.
Is there any way to easily test the sped of my new card w/o a drive to plug
into it?
