DISK IO could also displayed with file system related ? not only displayed physical disk. as maybe we don't know which file system used higher Disk IO.
such as exists disk sda, two part in it. one is /dev/sda1 mount on / , another is /dev/sda2 mount on /home, then we can clear / and /home are using higher disk IO

Regarding Disk IO, we can obtain information about devices such as /dev/sda, /dev/sdb, etc.
