@rnd256 I have the WD MyCloud EX4100 - it's ready to go out of the box with some, mostly optional configuration. It has four actual hard drives in it and the related controlling software/hardware.
This MyCloud Home looks like it doesn't have any actual storage and uses a cloud out on the internet, which would mean you wouldn't actually have your data stored locally.
I have never seen a wireless NAS. I would think you need the bandwidth of it being hardwired.You could perhaps put it where your router is, but I would think the laundry room would be a bad place for an device like this because of moisture and dust (and possibly also vibrations).
