I want to build my first unraid server. I have 12 HDDs with 32 TB. 4 WD HDDs with 4 TB and 8 WD HDDs with 2 TB. The 4 TB Drives contain a copy of the 2 TB Drives. All data is just movies. Since I have no experience in this, I understand that only the 4 TB Drives would be needed plus another new bigger drive for parity. Am I correct?
Just asking because of the size of the case. Have no plan what to do with 2 TB drives then.
