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

正常，2021 年初拿到手，同 94

很正常，照这个速度能用 30+年

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。

这么看来，丐版 mini 完全能用啊

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。

太少了。我 8%

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

两年用了 1%，所以内存还是大点好（是么？）

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。
