I just purchased the buffalo technology drivestation superspeed usb 3.0 pci express 2-port interface card ifc-pcie2u3? from Amazon. Everything install properly and I verified the power cable was plugged into the pci express board. The speed performance is poor when i do a transfer.
1. 20 mb/sec transfer rate to a ADATA 3.0 16 gb USB Drive
2. 50-65 mb/second to a WD My Book 1130 USB 3.0 Drive
I am running a a HP e9280t running Windows 7 64 bit Professional.
Any ideas why the transfer rate is so slow?
I would try a bios and a chipset update. After that I would try reinstalling the drivers for the card.
