Prior to the Quattro series, the embedded jpg in the raw file was compressed small, just big enough for most quick browse type functions.. When Quattro was released they introduced a full size jpg. The standard jpg can be extracted from the raw using the SPP batch operation, so u don't have to do jpg+raw if don't mind the extra process set through SPP. The new browser saves even that step.
