英睿达(原镁光) SATA MX500系列 SSD 硬盘要注意磁盘耐久度问题

2019年在京东买了一块英睿达 MX500 500GB的SSD硬盘,然后我就扔在机柜的塔式服务器里面跑Proxmox当系统盘用,也有部分VM用到这块硬盘,今年开始折腾k3s,也用这块硬盘做系统盘,没想到k3s装了一堆东西之后,每秒的磁盘IO达到了5MB/s,也没怎么在意。

上个月我进proxmox系统查看硬盘状态,看到wearout(磨损度)值还是84,心想应该没事的。直到今天我又查看了一遍,好家伙,直接97了。属实有些高了。

习惯性去看SMART的数据,结果显示是这些值:

注意点是202 Percent_Lifetime_Remain 0x0030 003 003 001 Old_age Offline - 97这个参数,直觉告诉我,这时候硬盘的耐久度应该是还剩下97才对。

问朋友也上网找资料,有说是磨损度是97了,有说还剩下97的耐久度。没有标准答案,于是我直接拨打英睿达的售后服务电话(回答问题的居然是个妹子,哈哈),咨询这个问题。刚开始妹子还说这个是还有97的耐久度的意思。但是我说我上个月看到的还是84,怎么耐久度还会增加的?妹子说这个得安装他们的软件进一步确认。然后要了我的邮箱给我发了软件。

由于我的是装在服务器里,没有GUI,于是下载msecli进行查验。然后看到原来真的是我的硬盘磨损度达到了97,只剩下3%的耐久度了。发出警告,告诉我硬盘即将到达寿命。

msecli看到的smart数据也和第三方smart看到的不一样。

在第三方SMART看到的Percent_Lifetime_Remain这个RAW值是97,很容易就认为是还剩余97的健康度

而在官方工具msecli里面查询到的SMART数据的Percentage Lifetime Remaining的值却只有3,意味着非常有可能下次开机就报废了

我也发了邮件回复英睿达官方的工作人员,一来是反馈我遇到的问题,二来也是感谢人家的工作。很快官方也回复了我,原文如图:

这个事情也是给各位提个醒,平时有事没事多看看硬盘的数据,无论是SSD还是普通硬盘,也不管你是消费级硬盘还是企业级硬盘,数据无价,要多留意。不说了,我要去备份数据了。。。买了一个硬盘在路上,明天恢复系统到新硬盘去。
