Thought not nearly as disparate in speed, I'd put the comparison as:
HDD = FDD
SSD = ODD
NVMe = HDD
I amazed some people in another website when I posed a question about the 3.5" FDD in my HTPC grinding randomly (supposed the anti-virus working). AT least it is a 5.25" or even an 8" floppy (were there 12/13" ones?)
You are correct about the protocol now being the bottleneck and there are some additional things like dual ported NvMe drives and the queue without SATA is 64k versus 1. SO thanks for adding the parts I left out and there are more.
But I guess my reference was out of place since I am old and lived the BETA (Sony better) versus VHS (everyone else cheaper) war. And it just seemed like that all over again. IN this case SSD is superior to HDD in all aspects for the internal drive of a laptop (once again my opinion). And as another has stated here like them I changed out a HDD to a SSD in a buddies machine and then he did not need to buy a new machine it was faster then new.
