Two drives only?! Should be negligible noise. The chassis cooling fan could likely make more noise. 🤣
NAS drives commonly use 5400 RPM (for lower power/heat) or 7200 RPM (for better performance), with higher RPMs like 10k/15k for enterprise, though network bottlenecks often limit real-world speed more than drive RPM for typical home/small business NAS. 5400 RPM drives offer quieter, cooler, more efficient storage, while 7200 RPM provides faster data access, especially for demanding tasks.
Seagate IronWolf NAS drives come in different speed tiers, with standard models often featuring
5900 RPM for efficiency in lower capacities, while higher-capacity and performance-focused IronWolf Pro drives typically run at a faster 7200 RPM, offering better throughput for heavy workloads, though some specific lower-end IronWolf drives also offer 7200 RPM for balanced performance.
Of course the cases are metal frame hung with plastic, no real sound insulation, Synology drive enclosures are
not specifically engineered for advanced noise mitigation; while some basic anti-vibration features might be included. The primary focus of the enclosure design is typically on cooling and airflow.
