Compressed DNG *isn't* a larger file format than PEF. In theory or
practice.
Ther *are* good reasons for using DNG for archiving, like unification
of the raw file and the XMP data.
Mark, I don't want to convince you (or anyone else) to use PEF format
instead of compressed DNG. Sure I'd use DNG on cameras doing it compressed.

Are there any disadvantages to switching to dng?
Larger files (22MB vs 16MB), hence more SD/hard disk memory required.
However, you can move around the hard disk waste by compressing uncompressed
DNG files before storing them, if you feel comfortable in doing that every
time you transfer images from the camera. However, you can also store PEF
files and then convert them to compressed DNG at a later time, if/when
you'll decide DNG will suite you better. Also remind that you can always do
PEF to DNG, while you cannot do DNG to PEF.
