Hy!
I use RAMDisk and VMWare to install WindowsXP. I create a 2GB hard drive image into memory, and create a VMWare virtual disk on it. The result is even faster than SSD drives. I use this install to test suspicious programs. So the data loss on freeze doesn't matter, but you have to calc with it.
(Sorry for bad quality, CamStudio 2.0 only able to 3.5fps, maybe next time...)
What system specs do you have
