3 Ways to Cut Your NAS (Network Attached Storage) Energy Bill
- 🌱
Enable hard drive spin-down after 15 minutes of inactivity — spinning drives account for 60–70% of total NAS power draw.
- 💡
Use SSDs instead of HDDs if possible — SSDs use 2–5W vs. 6–15W per drive during active use.
- ⚡
Schedule backups and media scanning for a specific window rather than allowing them to run randomly throughout the day.
The hard drive motors draw a brief surge during spin-up, and total NAS startup surge can reach 100–150W when all drives spin up simultaneously.
