I mainly want to use it for streaming my movies and series to the Mede8er media player, but as there's enough space, I will also put some ROM sets, and PS3 games (meanwhile 1.5TB), and free my internal disks a bit.

I also wanted to put my barebone backup, which although is backed up on my main PC and used through filesharing, it would be easier to only have 1 copy on a NAS where I also can access it from wherever I want.
