I own a QNAP 4 bay NAS TS-431-P2 with 3 Seagate Ironwolf drives (IronWolf ST4000VN008) in a RAID5 configuration. Now I want to add the 4th drive. I have seen a Seagate IronWolf ST4000VN006 that is currently cheaper then the Seagate IronWolf ST4000VN008 drive. Should I stick to the type of drive that is already installed or can I mix the existing drives with the cheaper IronWolf ST4000VN006. As far as I know the differences between the two drives are only in cache size and RPM.
