So I recently just built my PC and am looking to run Sony Vegas in the most efficient and fast way possible. Should I install it to my SSD for better performance and rendering speeds? Should I install it to one hard drive and then render to another? Any advice would be greatly appreciated.
Install Sony Vegas on the SSD and render to the hard drive. I use an SSD and have Premiere installed on it and save project files and render files to a hard drive. Really not a good idea, performance wise, to save project files and render to the same drive that the editing software is installed on. Something to consider in the future is a third drive. One drive (SSD) for the OS and programs, one drive for project files and a third drive for rendered videos. After rereading your post I strongly suggest you not try to save rendered files to the SSD. The space on a 120GB drive will quickly be filled if you save video clips (rendered or project) there.
