I can't really answer that question, although there are others here that will be able to. I use a WD Elements, the powered kind, 1 TB EHD with my Hopper and it works well. I've had that same EHD on a 722 and 3 different Hoppers and the transfers have alll been perfect.Thanks Bobby for the answer. Can I hook up a internal HD/SSD and connect it using this method as this will also supply the external power to the HDD... http://www.newegg.com/Product/Produ...87zjFNud9i2Tl_73u-IAYaAjDQ8P8HAQ&gclsrc=aw.ds
