So I have the starter Licence. I have 4 HDDs (3 drives, 1 parity), 1 NvMe as Cache, and the Usb with Unraid on it. I've attached a 2nd NvMe for Cache, and I'm getting the unraid device limit. Does the Usb count towards the limit? The other issue I have which ive never been able to figure out is in the Array size, the minimum i can select is 5 (cant go below 5), with 2 parity (1 of which ive left unassigned), and 3 disk drives. Is the problem the USB? or is it that the array size is 5 and counting it as such, even though i only have 4 drives there)?
