英特尔固态硬盘的原始读取错误率

我已经为几台服务器配置了一堆 Intel S3610，我对“原始读取错误率”值有点担心。工具显示所有驱动器都运行正常，没有其他错误，如下面粘贴的某个驱动器的完整 SMART 数据所示。

这些价值观有什么意义吗？

该Raw Read Error Rate字段通常采用专有、未公开的格式，或完全用于编纂其他信息。简而言之，不要只关注原始值本身。

相反，仔细检查normalized、threshold和worse数据：从中我们可以看到您的磁盘状况良好。

其他重要字段是Uncorrectable Error Count、Re-allocated Sector Count和Percent Drive Life Remaining：它们的原始值通常以绝对值编码，并且它们显示您的驱动器是健康的。
