请问大佬们, M1 mbp 固态两年磨损 6%正常吗?

    这是一个创建于 59 天前的主题,其中的信息可能已经有所发展或是发生改变。

    512g+8g ,今天刚测的:

    Available Spare: 100% Available Spare Threshold: 99% Percentage Used: 6% Data Units Read: 482,745,856 [247 TB] Data Units Written: 357,571,097 [183 TB]

    这个数据用量看起来还挺夸张的,但是磨损只有 6%,好像按照 SSD 寿命的一般计算公式算出来不应该才这么点磨损啊?不知道它这个 6%是怎么算出来的……

    btw ,今年 6 月的结果是磨损 4%、读取 182TB 、写入 136TB

    只有写入才算磨损,读取无所谓的。而且一般没必要关注这个。寿命肯定都够用。

    730 天算你天天开机每天要写 0.25TB ,原来写入量是那么大的吗

    不正常,一般正常用户电池用完直接就买新的了。

    磨损计算就是有个最大设计写入的阈值,用写入量去除那个值,零售的盘很多都留了挺多冗余的(为了尽可能不给你保修),苹果的这个基本上 100%就不可信了。

    这写入相比于正常电脑确实高了太多,不过两年磨损 8%,那看上去用个 10 年都没问题,感觉没必要担心。

    看起来像是最终锁死阈值,而不是保修阈值。按照行业 600 P/E 的惯例,这片 SSD 写过 300TB 就出保了

    M1 系列的磨损相比 Intel 是不是还是高了,2018/10 的 512GB MBP 至今

    怎么看磨损量啊?从楼主的结果看,用十年没有问题。

    是因为 8G 内存不够,长期大量 SWAP ,所以硬盘读写很多。

    大家的焦虑因为需求不同导致差异太大,正常搞点文本文件能有什么读写,放心用个十年吧。
