Thanks for your replies,

This is not for a specific application in mind.
I want to see if this is a best-practice I have missed, or if this does not
really have an effect in applications that do not have demanding disk I/O requirements.

To me it would sound logical if an application has specific performance requirements
and heavy disk I/O, a busy database for example, to have its own disk.

I see the advantage in having the OS / Applications in different physical disks, from the management perspective (creating a standby machine, swapping disks for the application, ...)

but does the OS on its own really need a significant amount of I/O access to the disk? I would guess not.

gnome-disks

GNOME-DISKS(1)							gnome-disk-utility						    GNOME-DISKS(1)

NAME

       gnome-disks - the GNOME Disks application

SYNOPSIS

       gnome-disks [OPTIONS]

DESCRIPTION

       gnome-disks is the command to launch the GNOME Disks application. Disks provides a way to inspect, format, partition and configure disks
       and block devices.

       The Disks application is single-instance. What this means is that if the application is not already running when the gnome-disks command is
       invoked, it will get launched and the command invocation will block until the application exits. Otherwise the existing application
       instance will be used and the gnome-disks command will exit immediately.

OPTIONS

       The following options are understood:

       --block-device DEVICE
	   Switches to the Disks application and selects the block device given by DEVICE (for example, /dev/sda).

       --block-device DEVICE --format-device [--xid WINDOW-ID]
	   Shows the "Format Volume" dialog for the block device given by DEVICE (for example, /dev/sdb1). If WINDOW-ID is given, makes the dialog
	   transient to the given XID.

       --help
	   Prints a short help text and exits.
