The external disk isn't going to be blindingly fast, however you use it. For Windows in particular, it's probably going to be more conservative in caching the external drive than it would an internal one. Any large or unindexed queries are likely to be a bit painful. I do use an external drive for some work, though, and it's usable. I have all of postgresql and the tools I use installed on the drive, with nothing for that instance installed on my laptop. I just have the external drives bin directory early in my PATH, so I can plug in the drive and do pg_ctl start, and it all works. That's on a mac, I'm sure you could do the same with Windows.
