Ans. Plex provides you a great platform to make your own collection of movies and access it from any of your devices over a network. With that said, if you keep that vast collection of movies stored directly on your computer, you will eventually run out of storage space. Hence, it is always preferred to keep the media collection separately in an external hard drive as it’s simply more convenient. You can directly join the hard drive to any other device, and you also get to keep the storage space on your computer empty. So, it’s better in all ways.
