Video shows how shouting at your hard disk reduces its performance
I came across this video which unnervingly demonstrates how shouting at a hard disk actually reduces its performance.
The theory is that vibration has a significant effect on disk latency. With probably too much time on his hand, our protagonist here videos himself yelling into a live JBOD* system. Amazingly, the latency shoots up in tandem with his shouting on a separate monitoring system.
Some might point out that a data center is hardly quiet in the first place – something to do with the frequencies of the human voice perhaps? Anyway, it might be a good idea to keep your invectives in check the next time you get upset while working on your laptop or desktop. For all your know, your hard disk drive might just be eavesdropping.
* For the technically disinclined, JBOD means “Just A Bunch of Disk” – and is the opposite of RAID. Essentially, a JBOD is, well, a bunch of hard disk drives that are separately managed and accessed.
You got to check out the video:

It would be interesting to test if talking sweet things to them would increase performance
For all you know, that *might* actually work. Something about soothing harmonics making them spin faster… In fact, I’ll post it here too if you create the video
It might also be useful to keep those “screamin’” high speed drives in a rack far away from any already slower drives.
