I ordered a MacPro this morning with the base hard drive (320 GB). I'll also be getting two 500 GB drives. I plan on using one of the 500 GB drives for the OS, apps, and most of my every-day data. The other 500 GB will be a Time Machine backup. The 320 GB drive I'd like to partition into two images, one being 275 GB and the second being the balance (35-40 GB I'm guessing). Onto the smaller partition, I was planning on installing Windows for Boot Camp purposes. My question is, can I also run Fusion or Parallels off of that Boot Camp Windows partition? Or do the virtualization programs create/require their own "file" that houses the Windows install?
