Emphasizing the above, the study a few years ago of disk drives at big HPC centers found that they don't follow a bathtub failure model. Rather, there are very few infant failures, and wear is noticeable starting in the range of 1-2 years in service.
- lmm 13y agoThe google results I saw were more like an exponential curve, i.e. a memory-less distribution - which would mean old drives are just as reliable as new ones.
- hga 13y agoThe HPC paper struck me as a lot more detailed, rigorous and useful. I read the Google paper later (assuming we're talking about the same one, they came out at roughly the same time), and the only useful takeaway I got from it was that disk companies seem to have solved moderately high temperature issues, Google actually saw a correlation with longer life and higher temperatures.
