Question about Dreambox One Ultra HD

Hi, I need to get a new DB now as the old one is starting to wear out. Questions ? 1. is recording to an external hard drive as easy as with the 8000? 2. is it possible to record in 4k (USB 3.0 interface)? 3. is the harddisk switched off by the Dreambox when not in use ? 4. SRF reception with card without problems ? 5. Sky possible ? 6. Netflix, Amazon, Dazn and Kodi possible ?
