關於 硬碟 溫度 與 壽命 的關連,以下這篇文章正好有提到。

Estimating Drive Reliability in Desktop Computers Consumer Electronics Systems (By Seagate Technology)

裡面有一段敘述Temperature

(節錄)...The following table shows the decrease in first-year MTBF (at 100% duty cycle) as ambient temperature increases above 25 C.

℃ Acceleration Derating Adjusted
   Factor    Factor  MTBF
25  1.0000    1.00   232,140
26  1.0507    0.95   220,533
30  1.2763    0.78   181,069
34  1.5425    0.65   150,891
38  1.8552    0.54   125,356
42  2.2208    0.45   104,463
46  2.6465    0.38   88,123
50  3.1401    0.32   74,284
54  3.7103    0.27   62,678
58  4.3664    0.23   53,392
62  5.1186    0.20   46,428
66  5.9779    0.17   39,464
70  6.9562    0.14   32,500

From the table above, it is clear that as the ambient temperature rises, the derating factor and the adjusted MTBF become significantly smaller...(節錄)
