There's no question in my mind: all original files get archived unless it's truly junk - OOF, blurry, way bad exposure, accidental trip of the shutter, etc. You can archive the PEF files on a disk somewhere, as I suppose you're doing, and work with the DNG files on the computer - save disk space on the 'puter and still have originals stored elsewhere. I'm not convinced that using compressed formats is the way to go. Heard a few horror stories, so why tempt fate?
For my own work, I always save the original file - scanned files are about 140mb - I don't care about using "too much" disk space.
