I think the speed issue is due to the amount of data you would transfer as 2GB is quite large and your PC probably has USB 2 Ports. Which for that amount of data isn't that quick. If you have a new PC with USB 3 ports then it will be quicker. If your PC does not have USB 3 it is probably a good idea to buy the hard drive with USB 3 compability as then you are future proofing your investment. USB 3 drives do work on USB 2 PC's but at USB 2 speeds.
