When we shop for a new iOS device like an iPad, iPhone, and iPod we tend to keep in mind the amount of storage we could buy because we want to be able to bring our Media with us so we can watch Movies, TV shows, and Music.
Most People want to enjoy watching their media without worrying about Storage, internet connection speeds, and eating through our Data Plans
Apple sells iOS devices that come in 16gb, 32GB, 64gb, and 128gb but what about the Apple TV 4? why only 32GB and 64GB?
Apple figures most ATV customers will just stream content via DLNA/UPnP or use home sharing for content we purchased on iTunes. So the small hard drive is to just store Apps and data
I don't think apple would imagine that people may want to download Media to the ATV hard drive so that we can use the Apple TV in the car, like i did ( Apple TV 4 in The Car detailed ) or bring their ATV to a Friends House
There is an app that allows you to do just that. Save your collection right on the ATV hard drive itself
Watch the Youtube video on my channel "AskUncleDave"
In this video i give you an overview of all the media apps i use on ATV and if you skip to 12:20 you will see the app that allows you to download Media to ATV for offline use.
I don't want to mention the name of the App in the article. So Apple, you will just have to watch the video to find out!! Apple, Please don't Pull it from the App Store
