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

@sq125 安装 homebrew，如果 brew 命令找不到的话需要 export PATH="/opt/homebrew/bin:$PATH"

@MaverickLee 不是人品爆，是 SSD 厂商默认一小部分人一定会用坏的，我是不同的电脑用坏的，而且坏的 SSD 都是经过三星和因特尔等售后的检测的，不是人为损坏，其实我就是虚拟机用得比较频繁。

常规的 256G 的 SSD 有 150TBW，这么算 1 个月用 20T 还是很危险啊

@mnsw 理解，我觉得前面确实说的过分了，但是封号还是不应该，降权，禁言都可以。

群晖 nas 同步文件的飘过，nas 还做了双备份，从此不怕 ssd 挂掉，ssd 挂掉丢数据的几率那是比机械硬盘高多了。

虽然 47 楼带节奏随意『调侃』缺乏礼节，彻底 ban 确实惩罚过度。像楼上说的，如果不是连续发布恶意言语，禁言或封禁几天都可以啊。大家觉得呢 @Livid

@mikeven 真的吗？
我手上这台（ 250G SSD ）显示写了 117TB，Percentage Used 只有 14%，如果 TBW 只有 150TB 的话，应该 78%级别的。
