Marko,
I haven't done this myself, so use at your own risk, but from the archlinux
wiki, there's an example of using udev to set one scheduler for non-rotational
disks and another for rotational, which sounds like a good general solution for
what you're looking for here:
https://wiki.archlinux.org/index.php/Solid_State_Drives#Using_udev_for_one_device_or_HDD.2FSSD_mixed_environment
Cheers,
-Shaun
