Na you missed much more. Its why I said wach the presentation cuz I wont be able to explain as well but Ill give it a shot.

Cerny said there where more hardware implementations than just raw ssd speed. Like the 4 extra PCIE4.0 lanes straight from the apu to the SSD, allowing it to skip the ram, the xbox has no such things. having 12 chanel memory vs the xbox 8 or 4(we still dont know, its most likely 8). The soc dedicted to handle data wich the ps5 has an equivalent of 9 ryzen cores while the xbox has a 4 cores equivalent. Cerny mentioned that there are other bottlenecks that limit data transfer speed so hdd's and sdd's dont run at their full speed all the time and the ps5 has hardware and software for that. The xbox only has sotware.

Again, Im not the best to tell you what this all translates to, but its much more than the 5.5 vs 2.4 raw speed. And I think we saw  a bit of this on the start up comparisons they have both made, the xbox had games start in like 4x the speed of the previous gen wich was like 12s vs 54s, while the ps5 was instant almost. under 2 sec wich was just the button presses and the fade to black between inmages. it was insane. But again, thouse where diferent games we might need to wait untill the same games are compared to really see.

Most of the things you are mentioning here directly tie into what gives us the raw/compressed figures. 12 channel... so the raw data speed of PS5 is much higher than XSX.... 9 ryzen vs 4 equivalent, which is why the compressed figures on PS5 are so much higher...

This is just breaking down why the PS5 figures are higher, it's not something separate.

No you oversimplifying it and omiting specs. Like not even mentioning the 4 PCIE4.0 laned with direct acces from the apu to the ssd. The PS% is suposed to stream data directly from the SSD and from ram at the same time while also suposed to use the ssd as ram and some are speculating that the ps5 can run the OS and other background task bypasssing the ram cmpletly and reserving all 16gb for graphics. Remains to be seenn though its all rumors and speculations.

The 12 chanel vs 8 or 4 channels ssd is another thing. While yes each chanel is a factor the overall speed, each chanel has a limited data cap wich directly afects tranfers. as data is split between each chanel, but if data is on the same chanel in goes in order so one has to wait for the other and in case that data is sensitive it need to waait for it and stops the transfer of the other lane. Thats one of the reasons storage usually dosent transfer data as the top speed advertise. Having 12 chanels means that there is less chance for that to happen and has the the ssd working more at top speed.

Yes the ryzen equivalent is more to do with how much more work needs to be done. AS far as im aware. 

This guy explains it very simple and more in depth. ignore the click baity title of the video. he barely mentioned that.
