I just had to rebuild my pc and added a 3rd 4tb drive in order to setup a raid 5 array. Raidxpert only gives me the options of JBOD, Raid 0 or Raid 1. The other are grayed. I have all 3 disks selected. This is on a windows 10 with MSI motherboard X370 chipset I think. Ryzen 7 cpu. Something I am missing. Windows is not yet fully upgraded back to the latest version but it is working on getting there.
