How many hard disks are actually in there? If one seems to break, can you replace the hard disk with a new one yourself?
There are two 10TB hard disks in it. (Hence the name "Duo") Yes, theoretically you can change the hard disk yourself, but it is not designed for this. If you already know that you might need more memory in the future or you are afraid of defective HDDs, I would buy a RAID.
