thanks atm i only have four 4Tb discs so set up one as parity and the others as an array, so decided that disc 4 will only be used for files and documents so excluded that from the other shares and have set up a media top share with folders below for the other two drives as this will only be for plex. i had a read of that and got confused, but liked the way you said about only spinning up the drive that's needed that was one of the reasons of coming from truenas to unraidAs said, you can do what you like. However I think it is worthwhile reading the Split Level section on this wiki page to see if it influences how you want to do it. It uses a hypothetical media share as a worked example so very relevant.
Split certain ways and using different allocation mechanisms can save you spinning up hard drives if you are the type of person to binge on a boxset for example. Every little bit of energy saved helps in this day and age!!
