By "non edited" do you mean before and after comparisons or just somewhere to store shots you are never going to edit?

You can use Lightroom for either of those scenarios very easily. I just manage everything in Lightroom, if I'm not going to edit the shot I just won't go to the develop module. Makes life much easier and there isn't really any size constraints on a LR catalogue. Everything goes into LR from camera phone shots through to DSLR shots. I never ever use anything but Lightroom to view or search for photos any more.
