Massive Google hard drive survey Google releases data of their HDD experience: "One of those we thought was most intriguing was that drives often needed replacement for issues that SMART drive status polling didn't or couldn't determine, and 56% of failed drives did not raise any significant SMART flags (and that's interesting, of course, because SMART exists solely to survey hard drive health); other notable patterns showed that failure rates are indeed definitely correlated to drive manufacturer, model, and age; http://www.engadget.com/2007/02/18/m...resting-thing/ |

Too bad they don't include company names & drive models... |
that pretty much kills the business of harddrive coolers |
not quite, as without active HDD cooling I see temps between 45-50, which is where the failure rate gets higher in the charts; most HDDs with active cooling are between 30-35... almost perfect :) |
My hdd's are between 28°c and 34°c with two quiet 92cm fans running at 6V. Cant really put the lower than that (or they wont start)... As for SMART: indeed, it's not really a good diagnostic tool. I've had 2 defective hdd's lately and both were pronounced in pristine health by SMART. |
okay, but SMART can't detect everything. It only detects whether your hard disk is wearing out or not. It can't predict a sudden failure. |

I am in trouble; my Hitachi 160GB SATA is running at 27°C normally and never exceeded 33°C in the last two years. I'd better put a heater there. |
