Hello everyone, the Wi-Fi router that I have, it has two USB ports, one is USB-A and the other one is USb-C.

If a USB hard drive or SSD is connected to the router through one of these ports, is there an app available that provides a reliable cloud storage? 

 I have tried a few FTP apps, but the cloud storage is never reliable and many times they do not connect very well. Is there something better out there?

Thank you
