Never tried an SSD, i wasn't aware of the last free page deletion thing.. what's a free page? I'm not familiar with that one..

However I did try the Ram Drive and after some tweaking, its quite good but the one I tried only had a max of 4gigs useage. Before I changed my "undo" amounts, the folder file size grew to such a point that it would cause Poser to shut down.. once I figured what the problem was, super fast!
