I usually allocate 20GB. But since it is dynamically allocated (at least that is your choice), it does not really matter. It uses only as much as needed.

The files always start out small and grow to a max of whatever you set. So, I usually set it to something like 60-80GB to ensure that I have enough space. It's rare they ever go over 5GB.

I would have to agree with whs on this one. In fact, when I first saw this thread title, i thought you were talking RAM, Which is my main issue with VMs

Virtual Box works perfectly well if you give it 1GB of RAM - especially with Linux as a guest. I have done that on a system with a total of 3GB of RAM and am very happy with the performance of the Windows7 host and the Ubuntu guest.
