With a 8TB internal hard drive (HDD), you can store many large files. That's one of the reasons to use it in a workstation for video editing, for example. You can also easily connect a 8TB HDD to your NAS. With a single 8TB hard drive, you'll have enough room for at least 175 4K movies of 2 hours each, 880 music albums, or 800,000 photos. Thanks to this, you'll be covered for a while after installing the internal hard drive.
