10: Acdsee Pro

Unlike standard photo viewers, Pro 10 was designed for speed. It does not import your photos into a proprietary catalog (like Lightroom); instead, it reads your hard drive's folder structure in real-time. This architecture makes ACDSee Pro 10 incredibly fast for browsing high-resolution RAW files, even on older spinning hard drives.
