Microsoft recommends 15 GB for Vista, Adobe recommends 1 GB for Photoshop, plus 1 GB for Dreamweaver. How is that all going to fit into 8GB Parallels is allocating? I just don't wanna waste a buncha time setting this thing up to discover, I should have set it up with 65GB of virtual space, and have to go through the entire procedure again. What size virtual drive should I set up?
The 15GB recommendation would be just a comfortable range, as is other Vista requiirements, which is different from the XP days, when it was rather too tight. Then again, I'm quite happy with running XP inside a 2GB virtual HDD... with 600MB of room to spare.
If you plan on using it a lot, anywhere between 20-40GB depending upon how much space you have on your Mac side. I find that any less and my users come back screaming about not having enough room.
It depends on what you plan on using it for, and where you intend to store your data. If you take advantage of Parallels Shared Folders, and store data outside the VM partition (i.e. on the OS X side somewhere), you might be able to get away with 8GB. If you plan on loading Office, 8GB might be a bit thin. I've get 20GB fixed partitions for XP and Fedora Core 6, with my XP data using PSF over to the OS X side, and find these are fine.
