So there is no real reason to install programs in different drives, I can just install them on the same Default OS drive.
Space being the only real issue. But applications (apart from games) don't really take up that much space. I have a 128GB SSD. Win8Pro, and ALL applications apart from games installed on it. Adobe Lightroom, Corel Video studio, Paintshop Pro, MS office...etc, etc. Currently about 50GB used space.
