Here you will find the latest USB3 driver for your MB; GIGABYTE - Motherboard - Socket 1155 - GA-Z68A-D3-B3 (rev. 1.0)
other than that you need to be using a USB3 compatible cable and drive. I believe there are two USB ports on some of the my books so you need to be using the right one.

Actually there's one port ,As for the cable at one end it's a USB 3.0 on the other end it's WD own port that they have the ( my passport )

Then you need only make sure you've installed USB3.0 drivers.

I'm not certain of the exact Mb/s for my FreeAgent but it's more like 10x your speeds iirc. Wicked fast.

Do you have the cable plugged into the USB 3.0 port on the motherboard?

Do you mean bits or bytes/sec? (ie do you mean 25-45 MB/s).

For sequential data transfers your USB 3 transfer rates will depend very much on where the data resides on the disk. For my 1TB My Book Essential disks the outer tracks (~90% free disk space) will give ~85 MB/s. For the inner tracks (~20% free disk space) you get ~45MB/s. This is on large sequential transfers.

Caching and such affects things but I think it's simple radial velocity that dominates the speed profile..

This is what HDTUNE says - I don't notice practical results quite this high.

I suspect that file size also has a part in the speed transfer.

Mp3 files from internal 3.0 drive to a second internal 3.0 drive.
Approximately 56 MB/sec

WMC recorded .wtv files from internal 3.0 drive to a second internal 3.0 drive.
Approximately 107 MB/sec

If you would like a comparason, here is what I get. the 2 USB's are the same drive, the eSATA is a different drive, but all are 7200rpm.

Typically you will get 2.5-3 times the speed of USB 2.0 using 3.0.
