Have a look at the manual page for df if you mean full, or sar for IO performance - probably the -d flag, but you haven't given us the OS, so it's a bit difficult to be sure.
Still probably better with sar -d 5 | grep "hdisk5 " which you can trap to a file and shovel into something like Excel to draw graphs if that is useful to understand.
This will give you the IO rates every 5 seconds. Colume order is:-
The time may not be displayed though. If you want to force a timestamp, you might need to do something like:-

Physical disks
This subsection displays a list of hot physical disks. The maximum amount of physical disks displayed is the number of hot physical disks being monitored as specified with the -d flag. A smaller number of physical disks
will be displayed if other subsections are also being displayed. Pressing the d key turns off this subsection. Pressing the d key again shows a one-line report summary of the activity for all physical disks.
