I have zero issues with answering any questions that may arise, as far as possible
Indeed there are so many possible permutations to try that I simply lack the time to test everything personally.
Addressing storage attached to the router:
1) There are 2 internal m.2 ports which can accommodate storage drives. Unfortunately this appears to suffer from a similar degradation as using m.2 drives in the Olympus. The router draws around 5-6 watts but these drives can easily double power consumption, and perhaps even worse draw several amps of current as they run off 3v3 rails. This sortoff wastes all that’s good about the router being a fixed continuous current draw which does not vary at all when loaded, where the drives vary allover the place.
2) That leaves storage connected to the USB port, powering it from the USB port creates similar issues as 1), its a bit more benign as it runs off 5V in stead of 3V3, but still very much audible.
3) Naturally you can use an externally powered USB drive, that solves that particular problem, but we currently only have ext4 filesystem support (linux), and not all drives work. So we’re currently working on adding support for multiple filesystems like AFS (apple), FAT32, NTFS (windows). This is not very difficult to do and I expect this to work pretty soon, aka TBC

It’s an interesting option for sure, your music collection will always be at \\192.168.100.1\usb and you can just plug the drive into your mac or windows desktop to copy additional music files to it or create backups etc.
