It's a portable device, everything on it needs be backed up frequently in case of loss or theft anyway.

I just wanted more storage for media for when I'm not connected to my home setup and/or into a fast internet pipe, and also didn't want to pay apple 1000% margin for 2 commodity flash chips.

Use it for some throughaway big files stuff or backup with something like backblaze

running a parallels windows install off one, no issues. macos does unmount if battery gets really low but not really an issue after reboot or replug.
