Wow, still using disk and PCIe storage? You look like a flash-on victim, darling – it isn't 2014

This is quite a simplification. There are plenty of situations where jobs are using remote storage (SAN say) to access large datasets, which can't possibly be replicated locally due to the data size. In these situations the local disk is hardly hit, and file access is normally sequential, so the criteria you are quoting (access speed, or basically random access latency) is totally irrelevant.

I'm sure there are applications that this sort of architecture would help, but there is plenty of stuff where this is not the case.
