L1/2/3 are CPU caches, not SSD. Though there is a good chance these are mostly firmware optimizations, not hardware. So still not an apples-to-apples comparison of cpu design.
Why did you omit the reference to "file system"?
Are we supposed to ignore the fact that a linker's main job is reading object files and write the output to a file?
I find this sort of argument particularly comical given a very old school technique to speed up compilation is to use a RAM drive to store the build's output.
