wow, only 22gb in 13 years? Do you lower your media's resolutions before archiving them? I thought about doing that with most of mine... but I would still need to go through the collection one by one to avoid doing it on my favorite ones even if I used exif metadata to rate most of them.
All photos are ~1.2Mb jpegs straight from a Nikon d3100 these days. I don't archive raws or process them other than perhaps rotation. Videos are h264 with a reasonable profile although this will change one day.
The key to keeping it contained is to not keep everything. I'm not afraid to throw away stuff.
