你的應用 資料寫入量 比 資料讀出量 有明顯大 你的應用比較特殊.

就一般系統碟而已
只是常下載
網頁多開

不知道是不是這樣
導致暫存大量寫入C槽
TBW 400TB,寫入26.6TB,換算起來是使用了 6.65%
可能是 SSD firmware bug,報反了

可以再試著觀察一陣子,看寫入超過28TB時,健康度是不是變成7%

那用你的算法. 算一下這一顆SSD的健康度囉.




2%
等待歸0中

昨天已備份,感謝提醒

03還是64(100). 01和0E都還是0. 這SSD暫時應該不會出什麼事情.
說不定是軟體出錯
問原廠看看吧

原廠說可以送修
我是打算壞掉或0%時再送修
systemctl
0%跟壞掉是完全兩回事,依目前寫入量進度用到0%很容易達成,要用到壞掉要看運氣,運氣好隔天開機就起不來,運氣不好用了5年保固都過期了還是頭好壯壯
Hi systemctl,

Here is the inference.
While the heath index changes from 6% to 3%, the "spare space" index does not change at all (i.e. keep at 64h). What does it mean that "spare space" index does not change at all? It means that there is no new bad block while the health index changes from 6 to 3%. You know that the percentage used index (i.e. 5Eh and 61H you see from the snapshots) could be affected by (1) bad block numbers and (2) erase counts. Since there is no new bad block, it is believed the health index is affected by erase counts. Understand?
Nothing perfect lasts forever.

First You need to figure out how to calculate the 05 (S.M.A.R.T) value. And discuss with me again.

你這原廠好像沒有工具可以看見康度耶,第3方軟體有可能不準確,因為每家計算方式對應值都不太一樣,
你這健康度也掉太快了吧
用 PNY 的工具檢查看看 :
