这样的 mac mini m1 写入量正常吗？

各位大佬，我的 mac mini m1,2 个月不到。 这个写入量是不是有点多。

好家伙，比我一年都多

不算少，升级一下系统试试

我看了好多网友的 Apple Silicon 设备的 SMART 。

我发现如果用 Data Units Written 除以 Power On Hours 计算平均写入速率，基本都在 10 MB/s 左右。

OP 这个是 7.976 MB/s ，如果从这个角度看其实还算少的。

我平时都刻意控制硬盘写入，比如临时大量写入会开一个 Ramdisk ，禁用了外接电源时的磁盘休眠，我的这个数据是 6.186 MB/s ，OP 的并没有比我的高很多，所以我觉得完全不用担心。

@butanediol2d 为什么每秒都在这么巨量写？ 24 小时下载吗？我用 linux 写入非常少，不操作时几乎没有任何写。

遇到问题，升级最新系统-重装系统-买新机

[butanediol2d]

@makelove 我说的是平均，不是说一直在以这个速度写
