Professional performance and reliability
Designed to meet the needs of businesses and intensive infrastructures, the hard drives in the series Synology HAT5320 combine robustness and performance. Specifically developed for Synology systems, they are tested for over 500 000 hours to ensure perfect compatibility and uninterrupted operation. Equipped with impressive endurance and a high MTBF, these CMR drives offer durability and professional reliability, even in 24/7 operation.
Thanks to firmware optimizations and deep integration with the DiskStation Manager (DSM) system, HAT5320 drives deliver higher sequential read speeds than similar drives, ideal for video surveillance, post-production, or file servers. Centralized one-click firmware updates via DSM drastically reduce downtime while eliminating complex technical handling. By combining Synology hardware and software, the IT infrastructure becomes more cohesive, faster to maintain, and better supported.
Key features:
- Persistent cache protecting data in the event of a power failure
- Simplified updates via DSM without manual intervention
- Superior multi-client sequential performance
- 5-year limited Synology warranty
- Optimized for Synology NAS with rigorous validation
- Compatibility from 5 °C to 60 °C, and enhanced shock and vibration resistance
