[quote]The fire extinguisher system used at the Bucharest site worked by expelling a mix - known as inergen - of nitrogen, argon and carbon dioxide. [/quote] [quote]But, according to Motherboard, the high-pressure release created a sound that topped 130 decibels. A study last year by the German engineering group Siemens warned the nozzles used by some fire suppression systems could cause "fatal" damage to hard disks because of sound wave vibrations they sent through the air.[/quote] [quote]"The hypothesis is that sound causes vibrations in the HDD case that are ultimately transmitted to the disk spindle and head assembly, causing misalignment of the read/write heads to the data tracks," it said. "Because there are many different designs of storage system chassis and cabinets on the market, the issue of vibration caused by noise as well as structure-borne vibration has not yet been fully investigated." Siemens's research indicated that different server models were vulnerable to different noise frequencies, and if there was a match: above 110dB, most hard disks would deliver a degraded performance above 130dB most disks would stop delivery data above 140dB, most disks would suffer permanent damage and there could also be other unpredictable faults [/quote] Fucking science, man.
