8g 256g m1 MacBook Air，才用了一个月，硬盘写入已经 22TB+了，你们的多少了？

1 月 21 日到手，去掉假期，平均一天写入 1TB，这 swap 也太狠了吧
家里装了六七年的台式机的系统盘，写入量也才和这个一个月差不多，照这么下去，用不到一年固态硬盘就得先报废啊
你们的使用情况如何？可以用下面的命令查看下

brew install smartmontools

smartctl -a /dev/disk2

电脑主板我记得是 2 年保修。这个焊在了主板上面，而且坏了没法启动，应该还是算主板坏
一个月 22TB，如果继续下去一年就是 200 多 TB，差不多就是同样容量的一般的 NVMe SSD 的 TBW 吧。应该活不到 2 年
如果只是单纯这样的话，保修期内又不要紧，坏了就换一台。主要是怕系统或者 SSD 主控觉得机器的 SSD 快写废了，给你疯狂限速，变得比 tf 卡还慢。正好 8G 的 mac 是特别吃 SSD 读写速度的，肯定会卡
而且不需要达到 TBW 就会开始降速，当然还和读写 NAND Flash 所需要的电压有关系，后期要加高电压才可以读写了，说不定 NAND Flash 的速度还会快一些，但是主控一般还是会选择降速吧

mbp m1 16G，写入 1.3T ，（ Power On Hours: 50 ），而且温度也只有 30 摄氏度
当初选择 16G 的原因之一就是担心频繁 swap 会影响硬盘寿命、增大能耗

三星 note2 时期的"字库门"就是因为 NAND 读写寿命耗尽吧?

不知道苹果有没有什么保障措施

可能是某些第三方软件的问题, 比如 15 年那会发现某狗输入法疯狂写入磁盘, safari 的 abp 插件疯狂写磁盘等等
