"For sequential writes, the story doesn’t change much either, although this is peak performance from writing into those DRAM caches."
Just a correction:
The data is being written onto the SLC cache buffer, not the DRAM cache buffer. No user data is written to or passed through the DRAM cache; DRAM in an SSD is used for logical block addressing only.
This is why DRAM has no affect on game load times.
SLC caching is where the controller treats part of the 3-bit TLC NAND as 1-bit per cell SLC NAND; this increases speed and endurance. Most of the drives tested have multi-tens of gigabytes of SLC cache; a couple have over a hundred gigabytes of SLC cache.
