Is running a VMware Fusion windows VM from a bootcamp partition faster than using a virtual drive? If so, is the difference dramatic or just 5-10%

The answer provided by is "It will be MUCH faster from a virtual HD. Also, you can't suspend, resume, or snapshot a real disk partition."

Sorry. Are you suggesting the opposite? – Jfly May 18 '13 at 16:39
The opposite of what? – John McC May 19 '13 at 22:06

I don't know the right answer but I would imagine it would be faster since it read and writes to an actual hard vice a virtual disk. I would be surprised if the benefit were that dramatic though. Keep in mind that with the Boot Camp option you lose the ability to suspend or snap shot a running system. I would recommend you asking the VMware Fusion twitter account, for an official answer

From experience it causes nothing but problems. If you ever need to boot to your Bootcamp partition you'll spend 20 minutes fiddling to get it Network/Wireless/Screen Res/Mouse restored because of the VMWare Tools install..

IMO it's easier to just use the VM as a virtual partition..

It will be a tiny bit faster. "Raw disk mode" is what running directly from a partition or device is called and there's a bit less software in between the VM disk writes and the physical disk. In practice I don't think you would notice running just a single VM.
