Yes, I can view the images via the hub, but I came across the storage space by chance.

How can I view videos stored on a local USB storage device?
All Arlo video recordings can be stored in the cloud. However, you can also connect a USB device to your Arlo base station or SmartHub to provide a second location for local storage of recordings.

Note : Only automatically triggered recordings are stored locally on the connected USB device. Manual recordings are only stored in the cloud.
To watch videos, the USB stick must be set up on another device, after that everything is possible to access the shared USB drive from anywhere, hope your question has been answered satisfactorily !!!

Yes, this is possible as long as the hub is accessible. So in the internal network or via VPN
