Monitor MB/s Disk IO Usage/Bandwidth - Use iostat from the sysstat Package

The binary "iostat" comes from the package "sysstat" and is available on all Linux/Unix like platforms. 

Use the "-m" option to give you what you probably want, which is to see in MB/s how much bandwidth each disk is doing.
