Why Not To Shout At Your Disk Array 125
Brendan Gregg of Sun's Fishworks lab has an interesting video demo up at YouTube demonstrating just how bad vibes, if expressed with sufficient volume in front of a rack full of disks, can cause a spike in disk latency. White noise, evidently, doesn't do them much harm. (Maybe they just feel awkward to get yelled at on camera.)

How this guy actually made the discovery.
He must have let off quite a bit of steam towards that rack.

Yeah, they get you less tense.
Is this a feature? (Score:2, Funny)
Might the the drives themselves be sensing the induced vibration via an embedded accelerometer and momentarily parking the heads to avoid damage? It seems like the marketing folks shouldn't have too hard of a time putting a positive spin on this behavior.

I would say yes. When I was a teen my mother walked into my room and started moaning about the mess.
Right then, windows blue screened and later I found the hard drive was completely dead. (Think it was a 15GB Maxtor or thereabouts) That cost me some pocket money to replace at the time.
If you have women living in the house, factor this into your backup procedure.

You made me wonder; if the the effect could be detected and "read", a you say, it would be possible to use it as a way of transmitting information to the computer by shouting at it.
I then remembered microphones.

hmm, bit of a chicken and the egg scenario there, isn't it?
is it slow because you yell at it, or do you yell at it because it is slow?
Either way, in the end it only degenerates into a downward spiral, where the computer gets slower and slower, while you get more and more pissed off at it and yell louder...
