Im looking to buy a hard drive that is 2tb. I will be getting a western digital black 7200rpm. Ive found two, one that is around 90 pounds and the other at 60 pounds.

The difference between the price is down to one being sata 3 and one being sata 2. This drive will purely be used to store my photos and videos, so it doesnt really need to be amazingly fast.

Does the sata 3 hdd make a big difference from the sata 2 one? Is it really worth me spending 30 pounds more and getting sata 3 interface. As both are completely identical.

Thanks

one being sata 3 and one being sata 2
For an HDD, there is no performance difference. The WD Black will not saturate a SATA II interface, much less the SATA III interface.

Marketing is the reason for the price difference.
