Oh dear.

I dont have any common operations that write to disk.

Excpet ones that create write once read many data, and by and by and
large those writes are RAM cached and completed in background#

So I dont really CARE

YOu are inventing hand wavey scenarios to support your case, but I am
reporting real life experiences.

I cant create data as fast as the server can store ir and I cant watch
the video/read the email as fast as it cam deliver it.

disk speed is NOT the bottelneck

Because all my computing uses the server in te first place, no large
data files exist on any other machine so I never have to move them
