The Ultimate Hard Drive Test: What Hard Drive is Best?
It was one year ago that I first blogged about the failure rates of specific models of hard drives, so now is a good time for an update. At Backblaze, as of December 31, 2014, we had 41,213 disk drives spinning in our data center, storing all of the data for our unlimited backup service..... ...

What Hard Drive Should I Buy? | Backblaze Blog | The Life of a Cloud Backup Company
My last two blog posts were about expected drive lifetimes and drive reliability. These posts were an outgrowth of the careful work that we’ve done at Backblaze to find the most cost-effective disk drives.

先來篇修正韌體文  http://ppt.cc/0c9M

然後現在開始補刀ST3000DM001這顆
很不幸我有兩顆
一顆是隨系統開機的data槽(使用時間長)
一顆是一週過電一次備份資料的資料碟(使用時間短)

這顆硬碟很神秘,每20分鐘左右會咖拉一次
C1就會 +1
就算你把所有節電都關了,他還是一樣跳給你看

我跟官方反應過,他們表示這是因為20分鐘沒用硬碟
怕硬碟被碰撞磁臂重擊磁盤造成壞軌
所以會回去他的停機場

But...人生最重要的就是這個But

我留下一個神秘數據...
有興趣的人可以算一下

假如你兩年都不關機的話...咳咳

----
為啥我會發現...
我外接那顆C1比內接的少100倍啊 (/‵Д′)/~ ╧╧
