I recently bought a Seagate 1TB 3.0 drive. My system is an Asus P7P55D-E/PRO motherboard and it has two 3.0 USB ports. My question is how do I know if my new drive is really performing at 3.0 or failing back to USB 2.0? Is there some test I can give it? Bruce

If you plug a USB2 device into a USB1 port windows normally throws up a message stating The USB device can perform faster if you connect it to a High Speed USB 2.0 port.". I would imagine a USB3 device would do the same.

As long as the cable is plugged in all the way, then it should work at 3.0

You can use an app like hdtach or hdtune to see the speeds. most usb2.0 drive max in the 27mb/sec area.

Transfer a large file between your external drive and your internal drive. If the transfer goes all the way through at a rate of more than about 40MByte/sec, then USB 3.0 is working. Although USB 2.0 can theoretically transfer 60MByte/sec, I've never seen a USB 2.0 controller that can do better than about 35-38MByte/sec at best.

And Hawkeye is correct - I actually tried this and found that if you plug a USB 2.0 device into a USB 3.0 port (or if you plug a USB 3.0 device into a USB 3.0 port using a USB 2.0 cable) then you get the "this device can operate at a faster speed" message.
