    Great advantage to store moves.
    Setting up the device only took a few minutes, which is a significant benefit. This enables me to store and download movies to create a comprehensive movie library. Furthermore, accessing all the movies and series I've downloaded is easy. I have been using this drive since March 2, 2019.
