Current Set-up: iMac (main workstation) --> 3TB Seagate External (location of iTunes folder) --> Apple TV Main Use: Streaming to main TV, or iPad when in house Problem: External Drive is failing. Space is running out. Questions floating in my head: What does a NAS buy me? Can I tack on an additional HD with iTunes pulling from them both? Is the long-term bang for buck of buying an HD enclosure better than continually buying Seagate and WDs? I'm aware of the audio issues with the ATV3, but the ATV makes things so simple for my wife to use, so I don't see myself moving away from it until the ATV4 comes out. The only other box I have to work with is the XB1, FWIW. Any help would be greatly appreciated. If I can clarify anything, let me know. Pretty basic needs, though. I don't really need to throw files on my phone for offsite use, but if it's an easy perk to grab, it might be something that I use.
