OK so i recently upgrade to an asrock extreme3 motherboard witch has usb 3.0 output on the rear. I was getting 48MBps with my wd elements 320gb external usb 2.0 drive in those ports. Having read that i`d get faster speeds with a usb 3.0 drive enclosure i bought this one from amazon http:// when i plug into usb 2.0 port i get 34MBps but when i change to usb 3.0 port i get a maxium of 2MBps. Was wondering if someone could tell why this is and if there's any way to fix it. Thanks.
USB 3.0 speeds under 2 MBps

Curios how did you measure the speed specially in MBps (megabits per second)?
but likely you need to install the USB 3 drivers they called Etron USB 3.0 driver

dohh by they the time i hit send this became obsolete lol
Also i would check the bios, the USB 3 support can be disabled there

it might not be USB 3 problem at all there other things that can cause slow speed
to eliminate best to test your computer with other know working USB 3 device,
and test trive on other known working computer
Defective enclosure you just buy,
The drive inside started acting up
Corrupted drive data (right click the drive, >properties> Tools> Error Checking)
Some program Like antivirus auto checking the plugged in drive on the background.

the speed will be determined by the Hard drive inside and the capability of the enclosure (sata to usb 3 bridge),
the interface (in this case USB 3) can't speed up the speed beyond the physical limitations of the drive itself.
thou the speeds with mechanical hard drive and USB 3 should be ~50- 100MB/s reading and around ~50MB/s writing
Those numbers are in MB/s Megabyte Per Second
but on your post you say 41MBps witch is megabit per second
so 41MBps is actually 41/8= 5MB/s witch is dirt slow USB 2 speed slow
