Don't know where you are getting this from, but it's literally not how every enterprise-level company runs.
You have something like and EMC Symmetrix all flash full of optane or nvme flash drives - hundreds of them. your data is striped across all of them. they're connected to something like a cisco mds. usually you have 4 paths to each LUN, and they're usually 32Gb FC. you can certainly have as many paths as you want if you need more bandwidth. The array also has 10-20TB of cache to front-end the flash. your response time is about 100-200 microseconds.
I don't know how much ram or disk you're going to shove into your server, but good luck running a bunch of half-petabyte databases in it, and expanding it for growth.
this is literally how 90% the world runs. your little theories are cute though.
