SBS2011 and Startech USB 3 SuperSpeed card

Hi

I have found a card recommended by Microsoft SBS specialist Gold partners to provide USB 3 to SBS2011 (Server 2008R2)

The startech USB3 PCI SuperSpeed card.

This card on the manufacturers website is claimed to support 2008R2 (basis of SBS2011) and has drivers for such.

Has anyone used this? as I am considering it to enhance the speed of the USB HDD backups.
