Don't Yell at Your Hard Drives: Sun Engineer

No, seriously don't. An engineer at Sun Microsystems' Fishworks lab discovered that yelling at your hard-drive causes sharp (yet momentary) increases in the hard-drive's latency. The engineer demonstrated this by yelling a portion of a server holding a RAID JBOD array, while monitoring its IO/s and latencies of the drive he was yelling at it. Each time he yelled at it, there was a surge in the drive's latency. The engineer posted his demonstration on YouTube. Now you know that yelling at your hard-drive isn't going to help, or is it? This opens up some interesting topics to research on, of how the rather loud environment enterprise hard-drives are put through in high-density storage environments impact on them, and to what extant vibration dampening helps them. The video can be viewed here.

noise can create vibrations and we all know vibration is bad for read/write/seek times on a HDD, i thought this was common sense ? but i have to admit i didn't realize it was that sensitive tho

I tried to convince my unit to go for SSDs instead of the 2.5in hdds for our laptops, that there will be less failure for us, and a more streamlined workforce, the chiefs reply was "too expensive".
and they wonder why there is so much field failure with our laptops.

Maybe this explained failure of my 2 HDDs in about 2 weeks. I have one 300/600W Sbu near comp, and 4 other speakers in room 2 150/300W and 2 35/50W. I like to use them very loude.

I'm sure that plus the magnetic field isn't helping

Ive always tried to minimize the sound and vibration around the hard drives. Sun Engineer's should get back to work and stop messing around.

Like a decade ago I had a computer that would speed up or unfreeze when I hit it. Wonder if doing that caused a program error or some sort of usage denial on whatever programs were causing the slow down.

Interesting stuff. I didn't want to take the risk that my drive's spindle motor could effect performance....so I unpluged the power to them. They do nothing faster then I've ever seen them do it before.

Verbal abuse doesn't make hard drives tow the line quicker? Well, I'm out of ideas, looks like they'll get the belt.....
