tl;dr, Vibration due to shouting causes measurable impact on spinning disk performance, increasing io latency. I guess this wouldn't apply to SSD's though?

So, it's 2018 - this was filmed 2008 on Solaris. Where is this UI for Linux? How can I reproduce the latency graphs in realtime on Linux?

Are datacentres transitioning to SSDs ? Or have they already?

I can personally attest that there is an extreme version of this effect: do not use hard disk in PA/DJ situations... I crashed several of my early disks due reading MP3 data proximal to a certain pair of 18" push-pull PA subwoofers...

SSDs are used in datacenters, though in my experience they haven't completely replaced spinning rust. Typically I see flash as a (large) cache layer or for more important stuff, with spinning rust for bulk storage.

Yes, for primary disks and cache tiers. Archival storage and large disks are still on HDD, usually through some SAN vendor that handles replication and performance.
