Is the default harddrive inside the Xbox One just insanely slow or something?

Not likely. This is a problem unique to Fallout 4. We don't see this issue in other open world games.

However, a lot of games do benefit in load times from an external HDD. I'm sure PS4 would as well if it supported external HDDs.

It supports internal HDDs/SSDs though and it's very easy to change.
