@ran - I used to have a setup just like this, but there were a number of dumb applications that kept wanting to use the C drive. I decided it would be easier for me to just keep my system files on the C-drive. As for the page file. There are a number of tips to improve performance. The basics include setting both the max & min of the pagefile to about 1.5x your total RAM. This keeps windows from dynamically resizing it. I don't believe there is any advantage to putting it in it's own partition, though putting it on another hard drive separate from your system files will improve performance because the hard drive head doesn't have to switch back and forth between the locations of the page file and the OS files. With hard drives being one of the most limiting factors in overall computer performance, it has the potential to be very noticable in some situations.
