Good news first. If you were to buy this unit, and just throw away the case and save the hard drive - you would SAVE about ~$100 from buying the bare hard drive alone. Yes, read that again, WD is GIFTING you a Helium filled, NAS quality (as in Enterprise grade) 8TB hard drive that retails for nearly $300 for a bare drive, for ~$190. Don't take my word for it, do a search for the WD80EZZX and see what you find - that's what they are sticking in this black box.
The competition, is sticking an inferior technology, pretty unreliable hard drive (Sept 1-19th reviews shows 12 out of 62 reviews with 1 star; that's 20% FAILURE) being stuck inside their box, and you are saving $20. Now, ask yourself - would you rather save $20 and run a 20% chance of losing your data? Are your taxes, your pictures, movies, games, homework, business receipts and emails worth the extra $20? Would coming home to find that years worth of data is irretrievably gone make you more angry, than saving $20 makes you happy?
Seriously, this is your money, not mine. My use is simple - this is a backup device for my Mac. This drive will typically come formatted with exFAT so it will work for both Windows and Mac. I never trust anything that comes from anyone, because I don't know nor do I trust any manufacturer. So, I ALWAYS format every storage device; this will be formatted for my Mac; so I will KNOW that the drives have no malware, no Trojans, nothing on the drive that I didn't put on there myself. I will then use it for a backup device. If I were to use it for my Windows machine, I would format it to NTFS and install my Windows Backup software, but this is my decision; you are (naturally) free do do what you want. I just suggest that you strongly consider doing something similar.
What good is having a backup device, if the backup device is unreliable? Would you trust a seatbelt that was defective? Would you use a defective parachute? Why would anyone use a defective hard drive in a backup device? The choice is yours, I humbly suggest you chose wisely.

Having said that, connection to a single device is incredibly simple and plug and play. If that is your intention of this device you will have a 5-star opinion.
6TB My Book Duo only had 5.5TB available. I know you never get the full amount of available storage as the description, but I didn't think it would be short by 0.5TB of space.
Trying to change the RAID-0 default to RAID-1 mirrored seemed easy using the WD Drive Utilities as it looked like just a button to change it, but it kept giving me errors. My work IT department needed to troubleshoot to figure out how to update the RAID, so it took some expertise. Once it got switched successfully to RAID-1, I have not had any issues.
WD Drive Utilities & WD Backup did not come on the drive [I wish it did!] so I needed to get those services downloaded and installed on my computer, which needed IT Administrators. Once installed, they are easy & useful to operate.
