external-hdd

I have here a company notebook, and because the HDD is full encrypted, I cannot install an extra partition for another system that I would like to use in my free time. And I really need another system, because this crap Windows here with that much of anti-virus, anti-spyware, anti-whatever on it is so slow and annoying.

What can I do? I could use an external USB HDD with another system. Because I would like to handle big files and so on, I don't want to use a USB stick. A USB 2.5 HDD + Ubuntu is what I think the best option.

Here are my questions:

Do I have to note something?
Does Ubuntu run well on an external HDD?
Do I have big performance problems (because of the USB HDD)?
Should I buy a very fast HDD for much money or it is not that important?

Any suggestions?
