It seems like drives would be better off with their own built in isolation. Wonder why it doesn’t work out that way. Elasticity of the materials and the gap between the axle and the arm? Space?
Hard Disk Drives (HDD’s) are one of the most impressive and important electromechanical devices ever created. The mechanics of HDD vibration is an obscure subject, and as a result, there is an aura of mystery surrounding vibration ...
The numbers are always mind-boggling to me. The precision, speed and reliability, all in a cheap mass-produced object. I suppose when you compare it to the chips themselves, those are also amazing. But HDDs just seem like they should be impossible.
Bought some 26TB HAMR drives recently. It uses solid state lasers to heat up the drive before writing. I shucked them from some Seagate external drive enclosures so we'll see how long my data will last. They're so new there's no failure data on them

I recall a video of a guy temporarily reducing hard drive performance by shouting at it
edit: here it is! https://www.youtube.com/watch?v=tDacjrSCeq4
That is not just any guy though. He is the guy.
The guy if you care about systems performance, in a detailed way, for sure!
Someone ask him how many OS kernel bugs he’s found now? He finds the weirdest things… a tally would be “interesting”.
next try shouting at a wafer stepper

I remember when I bought my first hard drive. It held 20MB and I was sure I’d never fill it.
