Ya gotta help me! Please! Well, not really of course but I hope somebody will here. I am indefinitely continuing to give in to the dark side because I have quite a backlog of good windows titles and it would be stupid to buy them again for PS3 even though I have considered doing that, being stupid sometimes and all. So, on to the question at hand. I have a two terabyte external USB 3.0 7200 RPM drive that I've only used for archival storage of game installers, etc. My time machine backups have their own USB 3.0 drive. Currently the 2 TB drive is partitioned 1 TB Mac filesystem and 1 TB FAT for Windows stuff but I really don't need that storage anymore. I think the only thing of consequence there is about 200 gigs of GOG game installers I could easily move over to the Mac side of the drive. So that leaves me with a 1 TB partition I could potentially use for running Windows and playing Windows games on if this setup would work reasonably well. And that is the million dollar question. Is USB 3.0 fast enough for this purpose? Can I do a bootcamp install into one out of two partitions on that drive? Do I need to make any specific changes so I can? Ideally it would be quite nice to boot off the external drive and free up 200 gigs on my iMac's drive that is currently used by Windows. While I am at it, could I move my Parallels virtual machine with Windows XP (around 40 gigs in size) to the Mac partition of that same USB 3.0 drive and access it there with Parallels? Would performance take any significant hit for doing that? It would be great to have just my Mac stuff on the Mac internal drive if I can do that. The reason I posted this here in the games forum is gaming performance is everything here. If it is going to be bad, there's no point in doing any of this.
