终端查看 Mac mini 硬盘读写数据，感觉超出我使用的范围

使用什么命令进行查看？

@Jaxen #1 /usr/local/sbin/smartctl -a /dev/disk0

no such file or directory: /usr/local/sbin/smartctl

@littlewing #4 brew install smartmontools

是不是 swap ，macos 这个还是动态大小

swap 和时间机器都会大量读写

不看就当没有，你这还是 mini ，坏了直接买个小板插上去就满血复活

我每周 time mechine 一次，每天工作文件备份一次。

内存(ram)不够的时候，会使用硬盘。

感觉差不多，也是日常办公使用

之前发现过两个原因：
一个是动态视频壁纸屏保，读的数据层层的涨，
上周是发现 ms_stores 写入量明显异常，一天打大概，读几十 G ，写 450G ，写明显异常，直接找了一个“临时”关聚焦的，
现在好了，我是非主力，但是 24 小时开机机器。

2022 年买的三手 2020 年 m1 官翻机，过去 3 年都是主力机，不过是 16g 定制内存版本，看起来也算正常

@littlewing #4 是没有这个文件，用 brew 下载 smartmontools：brew install smartmontools;查看 smartctl --version; 查看用量直接使用: smartctl /dev/disk0

同样 11 月第一批激活 M4 Mac mini

smartctl 显示的 Power Cycles 和 Power On Hours 都是错的，很多年了一直这样。written 和 read 是正确的

买了不到一个月的 m4 mini ，硬盘才用了不到 100g ，怎么能写 3T 这么多？ 64g 内存，swap 0
