OCC has published a review on the Antec Easy SATA
If you are looking for an external solution, I would highly recommend the Antec Easy SATA. Not only are you going to see similar performance from it when it is compared to an internal hard drive, but it is going to be able to stay with your case at all times, you are not going to need to have an extra adapter hanging around your computer using up a valuable outlet, and you are going to be able to switch it with another hard drive you have laying around very quickly and easily.Antec Easy SATA Review
