Backblaze 的「Hard Drive SMART Stats」這篇文章裡面提到了用 S.M.A.R.T. 的資料交叉分析硬碟存活的比率。
比較有趣的是對 Power_Cycle_Count 這個數據的解讀：
We’re not sure whether this is because cycling the power is bad for the drive, or because working on the pods is bad for the drives, or because “new” drives have flaws that are exposed during the first few dozen power cycles and then things settle down.
再對照其他幾張與 Power_Cycle_Count 相關的圖，通電次數看不出跟存活率有絕對關係 :p
