I just fired up my new rig and now I'm ready to load FSX. My new OS is Win7 64 bit Ultimate Full Version. My primary HD is a 240G Kingston HyperX SSD where my OS is loaded. I also have a secondary SATA 750G HD. My question is will it make any significant difference if the load the FSX in the Secondary HD instead of the Primary. I only have 240G in my Primary and a quarter of the capacity has already been allocated to the OS. I'd like to conserve space if possible. The FSX related files and folders now amount to around 25Gs. Also I have the FSX Acceleration disk to load which I hope is compatible with the OS.
