Ssd
英特爾 SSD 的原始讀取錯誤率
我已經為一些伺服器配備了一堆 Intel S3610，我有點擔心“原始讀取錯誤率”值。該工具將所有驅動器顯示為健康，並且沒有其他錯誤，如下面粘貼的一個驅動器的完整 SMART 數據所示。
這些值是否意味著什麼？

該
Raw Read Error Rate欄位通常以專有的、未公開的方式格式化，或完全用於編碼其他資訊。簡而言之，不要關注原始值本身。相反，請仔細檢查
normalized和數據：從它們中threshold，worse我們可以看到您的磁碟執行狀況良好。其他重要的欄位是
Uncorrectable Error Count,Re-allocated Sector Count和Percent Drive Life Remaining: 它們的原始值通常編碼為絕對值，它們顯示您的驅動器是健康的。
