I've personally always stayed with basic disks inside Windows VM's as it's easy enough to expand them (diskpart after expanding the vmdk) or just as easy to add another virtual disk. I just never saw any benefit in using dynamic disks. Anyone out there using dynamic disks inside Windows VMs? And if so, why?
I have done a little more research and polled some of my customers and I really can't come up with a reason to use Dynamic disks in a virtual environment. In my mind, the benefit of aligning the disk easily after creation out weighs the benefits of a Dynamic Disk after the fact.
