Apple TV 4K
Wi-Fi + Ethernet with 128GB storage
If you plan to use your Apple TV 4K primarily to stream movies, TV shows and music, or download a few apps and games, you’ll probably be fine with the 64GB configuration. It also makes a great smart home hub, and if you only need a Wi-Fi connection it has you covered.
If you download and use lots of apps and games or plan to use a hardwired Ethernet connection, you probably want the 128GB configuration. Thread mesh networking support makes it an even more capable smart home hub, with advanced connectivity and more comprehensive compatibility with your favourite smart home accessories.
