I'm really confused about the best way for running W7 through Paralles 5. All I need to run on windows is a forex trading platform. I've read that you get better performance if you install the virtual machine onto a separate disk.. So I'm wondering is it even possible to install windows through bootcamp + parallels onto an Express Card SSD and run it off of that? Or would I be best just installing it all onto the local disk drive using a separate partition for bootcamp? I'm new to running virtual machines so don't really know how it all works or the best route to go. I'm trying to decide between 13" macbook pro using separate partition on disk or a MBP with express card slot.. Also, I'm assuming the SD Card is too slow for this?
