For balanced performance and data protection, configure the drives in RAID 1 if redundancy is required; choose RAID 0 only when maximum combined capacity and speed are prioritized over fault tolerance. Maintain regular backups to an external location and keep DiskStation Manager updated to ensure security and stability.
