smartctl + 如何在磁盘上找到 XXX MBps 吞吐量

  • 772

我们想知道 - 单个存储卷读取或写入的速度有多快，以兆字节/秒为单位

例如 - 125MBps 吞吐量。

所以我们使用该smartctl命令来捕获 XXXMBps 吞吐量。价值

但我们没有从 smartctl 找到此信息

还有其他选择吗？

 smartctl -a /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.10.0-514.26.2.el7.x86_64] (local build)

    这个...

    $ lsblk -ap -e7 -o 名称、挂载点、FSTYPE、标签、RO、RM、状态、类型、尺寸、型号
名称 安装点 FSTYPE 标签 RO RM 状态 类型 尺寸 型号
...
    ...将为可用设备提供一个很好的表格（不包括循环：s）。

    从 NAME 列中选择一件事并在此处用作 $dev ...

    sudo hdparm -Tt $dev

    哦，你需要这个：
    $ sudo apt install hdparm
