On this report the authors write that "[the figure 4] shows that failures do not increase when the average temperature increases. In fact, there is a clear trend showing that lower temperatures are associated with higher failure rates. Only at very high temperatures is there a slight reversal of this trend." For the authors, slight increase means only 1% at temperatures higher than 45 C. The authors end saying that "We can conclude that at moderate temperature ranges it is likely that there are other effects which affect failure rates much more strongly than temperatures do." So, temperature is not a source of disk failures. There are other sources of failure like the number of power cycles of the drive and power-on hours (in my humble opinion, POH is more important on 2.5" drives than on 3.5" ones.) It is a nice and well written article. Thanks for the reference, I enjoyed reading it. _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
