This 2TB HDD includes USB 3 interface card. I just got mine today and it's a very nice quite drive with a power switch on the rear. Haven't tested on USB 3 yet as the interface card requires an internal molex power cable to connect to it and my one isn't long enough. A SATA to molex cable is included for those who only have SATA power cables in their PCs. The mains power adapter comes with UK and foreign adapters (continental?).
Reported USB 3 speeds are 3 times USB 2 for these drives, will report back once my interface card is up and running.
The only neg point so far is that the included USB 3 cable is very short and won't reach to my desk so the drive would have to sit on my PC base unit until I buy a longer cable.
Only 7 left in stock but Amazon keep getting more stock of these.
