Differences between Orbi RBR50 and RBR50V2

[jialins]

From local costco, I found RBK53 kit has both revision of RBR50 and RBR50V2.

Just wondering what's the differences between these two HW revisions?

From the data sheet, I see RBR50 has USB port and 4G flash, while RBR50V2 has 512M flash without USB port. Is it fair to say RBR50 is better than RBR50V2?

Does RBR50 support google voice and alexia? Thanks.

For the USB port on RBR50, how do I use it? I installed readyshare.  However it doesn't recoginize orbi... Can I share USB drive with it? If yes, how? Thanks.

That is about all that differs between them. Memory and USB port. 

The USB port is mostly for Printers and nothing else. Users have asked for Ready NAS support over the years however NG doesn't seem to want to support it as they have removed the USB port in V2 and now from Orbi AX as well. So if you need storage support, I would go with actual NAS device. 

Other than these items, the two systems are the same.
