Most people are puzzled as to how much hard disk memory they need. As they say, bigger is better. However, do you really want to store everything in one device? All your files, videos, photos, movies, TV series, etc., in one storage disk? I suggest that if you want to have a huge amount of storage capacity, better to keep them separated. Example, dedicate one HDD for your files and photos, and another for movies and TV series. That way, the HDD holding your important documents will have less risk of being corrupted or damaged.
