I just bought a heatsink for my drive so I managed to do a bit more experimenting.
I figured this might be worth testing so I tried comparing the PS4 vs PS5 versions of Miles Morales. I booted into the main menu (which is in realtime like R&C) and then started a new game and let the intro sequence play out. This takes about 2:30 minutes.
PS4: 5GB
PS5: 32GB
I haven't played the game yet so it's hard for me to make a controlled experiment with the portals. I did try to create a longer test by playing the first mission for about 8 minutes which resulted in 54GB of reads. I skipped the intro as in my earlier post which should mean ~5GB of initial reads plus another 49GB of data streamed over those 8 minutes.
I tried this one as well but I decided to skip the movie scene and went straight into the playable open world part. The initial boot alone was ~10GB and then playing around for ten minutes streamed in about 100GB. This would make the streaming rate about 3x higher than in my earlier Demon's Souls test.
I never went into flight mode so this is just from running and driving around the city.

I still haven't played through either R&C or Miles so I can't really comment on them more than this. R&C is the next game on my list though so I'll hopefully do a follow-up.

Test R&C some more, in special what is happening during portal/level swapping, because as you said, i expected much larger numbers there.
