I have been looking for something similar to this for years. The Wavlink holds one drive but can handle both small form and large form drives. I give it four stars because there is no support that holds the drive in place it plugs in and is held up by its pins. Some what of a flimsy design, every time I play around with it, I am worried, I am going to break the drive. I also, would like to see a light that shows me, it is transferring data. The only light is a dimly lite power light. All-In-All I am very happy with the device and it performs as advertised.
