Its USB 3.0. It's just the title is wrong. The description to the right states USB 3.0 and the best proof are the pics showing a USB 3.0 connector on the back of the unit...
Yes, but according to a review on the second page, it seems that the drive itself is too slow to be true USB 3.0...the reviewer said:
Works well but unsure about USB 3.0 capability
I have used this drive on both Windows (NTFS) and Mac and it works great with both. I will point out that I didn't install any software at all - I formatted the drive as soon as I opened the box.
My only gripe is I'm not sure how useful the USB 3.0 connectivity is if Seagate has put a slow drive inside. Write speeds were a very slow 15-20MB/s which is the same speed I get if I plug the drive into a USB 2.0 port.
All in all, it is good for a 2TB drive but don't buy it expecting a huge performance boost.
