You can configure RAID settings manually using the Mode switch on the rear panel of the RAID enclosure by

Important
• QNAP recommends using only one disk type (HDD or SSD) in a RAID group. If
different types of disk are combined in one RAID group, the RAID group will function
according to the speed of the slowest disk.
• If disks with different capacities are combined in one RAID group, all disks function
according to the capacity of the smallest disk.
