Google publishes hard drive expose!

Hard drive expose by Google-A hard drive white paper study from Google


Google has published a document on hard drive failure rates based on the study of hard drives at Google's data centers


Google's hard drive study makes for very interesting reading-and cannot be taken lightly since the sample size of Google's data centers is very huge


Google's hard drive collapse surprise finding 1:Hard drive failure not correlated highly with temperature


Google's hard drive failure study finds that there is no one on one correlation of temperatures with hard drive failure


Per Google's hard drive research,new hard drives prefer higher temperatures and older hard drives prefer lower temperatures and are susceptible to reverse temperatures


Google's hard drive research is in short suggesting that we shouldn't assume that all drives are equally susceptible to manufacturers


Google uses cheap and a variety hard drives from various manufacturers


Google operates one of the largest data centers in the world, and amazingly uses cheap hard drives with a combination of serial and parallel hard disk drives, with speeds from 5400 to 7200 rpm.


Incredible, that Google's large data centers uses hard drives that may be obsolete elsewhere


Google's hard drive research suggests that SMART hard drive parameters are not the only symptoms that aid in preventing hard drive failures


Firstly,Google extensive use of SMART hard drives (self-monitoring drives) is interesting


Further,Google's conclusion about SMART hard drives is a signal to SMART drive manufacturers that the data monitored is not good enough


Google's hard drive research summary


Get rid of hard drives after the

  • Hard drive first scan error

  • First hard drive sector reallocation error

  • The first hard drive probational count error
