Common Mistakes People Make With Synology NAS (And How to Avoid Them)
Synology NAS devices are powerful, reliable, and user-friendly, but many people unintentionally make mistakes that affect performance, security, and long-term reliability. Avoiding these common issues will help you get the best experience from your Synology setup.
1. Not Using RAID or Choosing the Wrong RAID Type
A common mistake is using a single drive or selecting Basic storage, assuming the NAS itself protects your data. If the drive fails, all data is lost.
Use Synology Hybrid RAID (SHR) or RAID 1/5 depending on the number of drives, and check disk health regularly in Storage Manager.
2. Assuming NAS = Backup
Many users store all their important files on the NAS without creating an additional backup. A NAS is storage, not a complete backup solution.
Use Hyper Backup, Synology C2, or another external/cloud target to follow the 3-2-1 data protection rule.
3. Unsafe Remote Access Configuration
Opening ports manually without proper security exposes the NAS to attacks.
Use QuickConnect for safe access, enable 2-step verification, and use Synology VPN instead of risky port forwarding.
4. Choosing EXT4 Instead of Btrfs
Some users still install volumes using EXT4, missing out on Btrfs features like snapshots and self-healing data.
When available, choose Btrfs for better data protection and faster recovery options.
5. Using Non-NAS Hard Drives
Desktop HDDs like WD Blue or Seagate Barracuda are not designed for 24/7 NAS use and can fail sooner.
Use Synology’s HAT3300 series, WD Red Plus, or Seagate IronWolf for reliable performance.
6. Skipping SMART Tests and Alerts
Ignoring drive health warnings or not enabling notifications leads to undetected failures.
Schedule extended SMART tests weekly and enable push or email notifications from DSM.
7. Installing Too Many Packages
Installing unnecessary apps uses extra CPU, memory, and storage, slowing down the NAS.
Only install what you need—such as Synology Photos, File Station, Drive, or Hyper Backup.
8. Avoiding Updates
Some users delay DSM updates thinking something might break, but outdated systems have more vulnerabilities.
Enable automatic security updates and manually review major DSM upgrades for safety.
9. Poor Ventilation and Heat Management
Putting the NAS in a closed cupboard, near heat sources, or without airflow increases temperatures and reduces lifespan.
Ensure proper ventilation, clean dust regularly, and adjust fan settings when needed.
10. Using Synology Only as a Basic Storage Device
Many people use Synology as a simple external drive without exploring its full capabilities.
Take advantage of Synology Drive, Photos, Docker, Surveillance Station, and other tools to unlock the full value of your NAS.
