I too am curious whether my WD TV Live could recognize 6TB or greater drives. But come on folks, the newer highest capacity drives are always near the top of the price curve. Stay “small” and still win. As I’ve posted on another thread, I have 32TB of drives all visible from both my WD TV Live Hub and WD TV Live boxes (and from laptops and IPADs).
Sure - this can be done. I have 16TB of movies so far and - with occasional gotchas - it all works fine.
1TB internal drive in WD TV Live Hub
3TB external USB WD Elements drive plugged into the WD TV Live Hub. (I don’t use the 2nd USB port.)
4TB WD MyCLoud connected to my local network
3TB USB External hard drive plugged to back of the above MyCloud (some, but not all MyCloud have a USB port).
3TB WD MyCloud connected to my local network.
2TB WD My Book Live (older drive with essentially same capabilities as a MyCloud) connected to my local network.
That’s 16TB of movies, all available directly from the WD TV Live Hub. And each of the above drives has an equal capacity USB drive connected to my home PC, that serves as a backup for the main drives. All of the backup drive are visible on the network, so in theory, all 32TB of movies are viewable. In addition, a 2nd TV with an “empty” WD TV Live media player can also connect to and play any of the 16TB of movies. As can the home laptops and IPAD, which can “see” over Wi-Fi any of the 16TB of movies.
Both the WD TV Live Hub and the WD TV Live media player are (of course) also connected to local network.
