Tips

For optimal performance and data redundancy, configure the two drives in Synology Hybrid RAID (SHR) mode. This provides one-drive fault tolerance while maximizing usable capacity. Use the built-in USB Copy feature to automatically back up data from external drives, and enable Snapshot Replication to protect against ransomware. Keep the NAS in a well-ventilated area to ensure efficient cooling and longevity.
