    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。

    @makelove 我说的是平均,不是说一直在以这个速度写
