I really want to use NAS for my iTunes folder but I have some questions. 1. Can my ATV use the NAS (iTunes folder) if my computer is off? 2. Is there a special way to set up iTunes on a NAS? 3. I have a wireless AC router and FiOs internet. I assume that plenty fast? 4. Does the NAS go to sleep and wake up when ATV wants to access it? Here is what i'm Looking at. http://www.amazon.com/Cloud-Persona...d=1451578467&sr=8-2&keywords=wd+cloud+storage I already use a USB3 HD for my iTunes library and it has worked flawlessly when my macbook is sleeping and plugged in.
