Video: Shouting at disk drive causes high latency, low morale
Here's a tip for everyone who hasn't made the jump to solid state: try to be nice to your disk drive. Brendan Gregg from Sun's Fishworks team wanted to see the effects of vibrations on his disk array, so he proceeded to shout at it. On video. Yeah, we bet that's pretty embarrassing for the drive in question, and what results is a sharp spike the number of I/O operations that take over 5ms to complete. Moral of the story? Yelling at your computer isn't going to make it run any faster. How about next time we see how it reacts to Ozzy, Mozart and warm, gentle nuzzles? We've placed video of Gregg's sadistic hardware taunts after the break.

next try waving a giant magnet in front of it for kicks and see if it physically drags the drives out of the bay ;) even if that doesn't work, fun will be had...
Looks like someone's been taking Mickey Rooney Crazy Pills.
He's hot, though.
I dont play Crysis becasue I don't have a pc that can run it... and what's this nonsense about you buying me?
What?!?! I can't hear you over all those hard drives!
Mmm, that Brendan's one sexy cub.

Wasn't that one of the ancient computers Strongbad used?!
I'll have to agree girls, he is cute...too bad he is insane... or at least..really really weird.
Admin screams at computer whilst geeky ladies seek to woo him away from said computer.
Have we just witnessed the birth of Skynet?
So good thing the girls are here on Engadget's comment system, won't have to worry about finding and creepy weird guys...
Except iEye
So constant screaming in frustration ultimately leads to more fail?
I think I'm finally starting to understand Engadget's comment system...
Explains why playing really loud Music on my Qosmio makes it freeze all the time...
I guess I should move on to SSD then....
Yelling never accomplished anything... but constantly slapping my old CRT display when angry used to do wonders for my productivity!
I used to have a CRT that needed to be hit to make the blue display, otherwise it didnt give me any blue.
My knuckles still remember the bruising they got when I punched my CRT right in the middle of the screen. I think the only thing that broke were my knuckles.....
I took a Louisville slugger right to the center of a 17 CRT one time...and that is a mistake you only make one time my friend. Yeah, it didnt feel good and I looked like a whuss when the bat just bounced off the front of the glass.
Yep! i did the same thing with 2 x 2 wood... just bounced. i smashed the plastic instead. darn stupid 486.

sorry for the first one. I could blame it on the commenting system, but I'm pretty sure that was "user error." :-P
@Karl Hackswell
I used an axe on my Trinitron when it died and it was very satisfying. So I guess the lesson here is that axes are better than bats.
Why would you post this?
Why would you comment?
To make people like you post comments.
As evidence to why Vista was so slow on it's release? I mean, all the people screaming about the movement of key configuration options, hiding all the networking options more and making it generally unlike their old computer experiences in every way...
Then they got used to working in it and SP1 rolls around about the same time and people stopped shouting causing their PCs to speed up!
It all makes sense now.
Wow, they must really be bored over there at Sun, huh.
These guys have wayyyyy too much free time on their hands. Sun should look into laying people off if they don't have enough things to do besides yelling at HDD.
Shock and Vibe testing is a very important part of enterprise level testing of servers and storage. Knowing how hardware will respond under different scenarios is important to know so limits can be set as to the operating conditions of the hardware. Sure this is an unlikely case, but you have to look at how soundwaves can effect the drives. Think about harddrives near anything that produces extreme amounts of sound (speakers or engines for example).
That's why they made solid state drives.
So the 600 watt concert speakers on the sides of my desk... maybe not such a good idea.
Come on engadget. I know it is a Friday after January 1st Holiday and a day before a weekend, holiday mood remains. You should still try harder to post meaningful news.
We all know, mechanical drives ie. Disk drive of any sort and hard drive with platters are sensitive to shocks and vibration. That's why there is a warning sticker on the packaging and warning words on the manual.
that's why there're fun experiments like this, because worrywarts such as yourself heed all warning stickers and spend the rest of your time hunting this site for hard hitting controversial news.
this is a fun fit of whimsy, and i suppose if they didn't post this story it would be instead replaced by something extremely important you are probably missing out on.
or it could be you're just as bored as they are.
Come on dude, the write up is funny and the 'mental picture' of someone yelling at there disk drives.., even funnier!
That's it! I'm dropping you as a friend...

Is this your first time here?
@tom: We programmers don't pay much attention to warnings, we worry about errors only.
Come on guys, I think dumb stuff like this is pretty sweet. lol
Guess I know why that Crazy German kid's computer was going so slow when he wanted to play Unreal Tournament ;-)
well good lord, so you are saying the lourder a machine room the worse your disk I/O is?
This is really crappy if true.
Soon, they'll be taking the fans out of systems because they are noisy...
I thought this was a pretty good test, so I just tried it on some of my subordanates. Apparently it increases latency in them as well. Next time i'll attempt the Crazy Train approach.
This has to be the most scientifically valid experiment I have read about all day. But then, this also the first thing I read today.
amazing shit
what about slapping the hard drive ?
I imagine the hard drive would then leave you and go live with family while it investigates filing for charges.
And what happens if someone shoves it in their bum?
(yes, I did say bum)
Let us know!
Sorry buddy, can't speak for you, but mine's an out only.
if you're making an omelette you gotta crack a few eggs.
Vibrations is a serious issue!
Not for women my friend. :)
Oh snap. Vibrations. Well, I'm fucked.
The sound reactive cold cathodes in my PC must be indicating heavy vibrations, seeing as how they're flashing to the beat of bass from trance songs, which is being blasted out of a 10in sub 4 inches away from the side of my case. Hopefully the heavy-ass nature of my full tower case (complete with a water cooling loop and an extra 15 pounds of radiator) will help to buffer the vibrations but oh snap! I should really find a place to put this thing that doesn't have heart-pounding, drive head crashing bass.
Wow, you must play some hardcore trance songs to require watercooling.
Pssst! Hey you guys at Fishworks, Ghostbusters 2 was just a movie!
