I don’t know. Was that interesting???
How much “vibration” becomes significant in any way?
I thought it might be “air pressure variation” as the heads do float on a very thing air layer. Could be both?
Seems to me that he could have stomped on the floor as a quick comparison/isolation of cause.
Somebody, play Mozart’s Fantasia in D minor. Maybe, it just hates Metal?
The days of brown, round spinning disks are numbered as well as RAID. Look for SSD’s and nanotechnology with data being split at the bit for redundancy, security and geographic disbursement for survivability. Replication and back-up will be a thing of the past. Data is becoming too large for that non-sense. People are tired of paying hotel mini-bar prices for proprietary storage monoliths.

“data being split at the bit for redundancy,”
It better be better than that crappy FAT & FAT32, one of the tables go bad and still the files are busted.
It’s so noisy in there it’s a wonder those disks work at all. They seriously need to look into water cooling…
#4 – No discernible data would ever reside on a single storage location. What you described would be merely a node. We could lose the entire data center and the data would still be available as long as you are an authorized user. We can control the data even if it has left the Enterprises network. We write the data in parallel so there is a performance gain as well.

“Backup will be a thing of the past”
Yeah right, tell that to the people at Journalspace, a blogging site with thousands of members, that just shut down today because they lost ALL the data on their servers due to a ‘mystery glitch’. All the data gone, gone, gone. They had NO traditional backup, instead counting on ‘data replication’, which worked wonders and replicated the ‘drive erase’ process on their replicated RAID systems.
For more info on Journalspace’s sudden and irretrievable demise, with complete data loss for all users:

When it comes to data security, tried and true is the only intelligent way to go… that means regular backup to non-live replicated media.
I wonder.. if you introduce the right type of vibrations, can you reduce latency?
“I wonder.. if you introduce the right type of vibrations, can you reduce latency?”
.. sort of like noise cancellation?
hums beach boys tunes at his disks…

Using water cooling devices won’t remove the need for having noisy air conditioner. Besides water cooling is PC enthusiast/gamer thing.
Water cooling is basically unheard of when it comes to enterprise/server/blade rack mounted hardware, where it’s so cramped you can barely fit in a heatsink as it is. They are not built like desktop PCs with PC cases with tons of empty space for dual graphics cards, and oversized HSF.
You need cool air to keep your hardware cooled, regardless if you’re using water cooling, or conventional HSF cooling. After all even with water cooling the heat is dissipated into the air with radiators.
The temperature of your hardware will not get any cooler than the ambient temperature in the room. Therefore you need an AC to keep the ambient air cooled, otherwise you end up recycling hot air back onto your hardware, build up more heat (like a snowball effect), and they will get warmer.
Large hard drive arrays produce tons of heat and I don’t think they make water cooling kits for hard drives. Even if they did it wouldn’t be practical in large drive arrays. And you still need an AC unit to cool the air so the hardware keeps cool.
