Thank You Lance.
Actually I don't care about the Public Share. I am the only person at home that uses the NAS.
My device (mycloud mirror 8TB 2gen) would be a perfect solution for me, but it really gets unusable if I turn on the cloud access, so I use it disabled all the time, loosing the main feature of the device.
So If this new device works smoothly as a mounted drive giving me the same speeds I get today (around 60-80 MB/s reading), and allows Cloud access. That it is what I need.
Just one more thing, does it allow DLNA streaming to a smart TV?
