I got a terramaster nas and I’m super happy https://www.terra-master.com/global/f4-5067.html

The main reason to choose it is that it is just a PC in the form factor of a NAS. You can just boot it from a pendrive and install your favourite operating system. I had a Qnap before, and while it was great to start, self hosting wasn’t the best experience on their OS.

this is a small form factor, it should be low power consumption (I’ve never measured to confirm it) and supports both nvme and sata drives. Currently I’ve an nvme for the OS and two sata for storage. CPU is powerful enough to run home assistant, vpn, pihole, commafeed, and a bunch of other Docker images. I just plan to increase the ram soonish because the stock feels a little constrained.

I did some experiments in the past. The nicer option I could find was enabling webdav API on the hosting side (it was an option on cPanel if I recall correctly, but there are likely other ways to do it). These allow using the webserver as a remote read/write filesystem. After you can use rclone to transfer files, the nice part is that rclone supports client side encryption so you don’t have to worry too much about other people accessing files.
