I have 4 USB3 ports on my home made router. Is there any issue in using these with linux software raid?

If they do not have some features then you won't have these features on windows, macOS or any other operating system either.

I have no reason to believe it would be anymore different than windows and macOS. Also, isn't raid configuration done in the motherboard bios instead of the operating system?

Okay. I won't be much help then. Sorry. Idk a thing about raid to be honest other than knowing it is an option in my motherboard bios.

USB software RAID should be fine since it's handled by the OS. The only downside I can think of is if you're using flash drives.

Yeah iv seen people discuss SSD features not accessible via USB adapter. Things like erasing and setting reserve size
