Besides speed, the main problem of spinning rust hard drive ultimately comes down to reliability: you have to baby them, one bad shock and the magnetic needle scratches the platter, then all your data is gone without any way to recover them.
Datacenters usually have redundancies just in case, but being that NAND flash is dirt cheap nowadays, the flaws of spinning rust hard drives are too great to overcome.
Why would running datacentre drives experience a bad shock?
Earthquakes?
Considering that the needle hovers like mere nanometers over the disk, something as simple as loud noises would cause enough vibration to affect disk performance, so the force needed to permanently damage a disk is really, really small.
I always love seeing that video in the wild, but vibrations affecting performance and vibrations causing damage are two entirely different things, particularly because that performance drop might be the needle parking itself to avoid actual damage.
As a personal anecdote, I've once installed Windows on a laptop while sitting in the back row of a car driving on not-so-great roads and while I wouldn't recommend it, the laptop was still good years later.
Speaking of, the entire concept of laptops wouldn't have worked before SSDs became mainstream if HDDs were actually that fragile.
Oh no, you've said the forbidden words on Lemmy! I can hear them coming now...
"Burn the heretic!"
*pointing and laughing
"I use arch, btw"
Well, this took place more than a decade ago, probably even before the above video was made, and I am actually using Arch right now. Still have a Win11 partition though. And another PC with Ubuntu, just to make everyone mad.
Nah, I use Fedora m'lady.
