My Seagate FreeAgent GoFlex 1.5 TB external hard drive runs at the same speeds (R/W around 35 MB/s) whether plugged into a USB 3.0 or USB 2.0 port.

I've had the drive for over a year, but just upgraded my computer and have USB 3.0 ports for the first time.

Any ideas on why I'm not getting USB 3.0 speeds?

From the review " Real World Performance ", you can see if you copy large file (8GB) the speed is 77MB/s, if you copy the small file (5GB) the speed is down to 25MB/s. And Look like your drive is fine.

Yes - I installed the USB 3.0 drivers and I don't see any yellow items in device manager. MSI Z87-G45.

Edited: I meant MSI Z87-G45.

Anyone have any ideas on this? I feel like this is a solvable issue, but I know it's hard to address given the number of things you might need to know. If there is any specific information that I can provide that would be helpful, please let me know. Thanks.

Ok, you're right. That's disappointing, but thank you. I purchased this drive in a weird (legit) way and didn't have a chance to research it first. Funny that for all intents and purposes (files < 5 GB), it only operates at USB 2.0 speeds. Thanks again.
