Stable SATA performance for demanding Synology workloads
The Synology SAT5220-960G is designed for mixed and intensive storage workloads where consistent SATA performance, endurance and Synology-system validation matter. It combines capacity-specific I/O ratings with power-loss protection and DSM-oriented drive management.
Capacity-specific throughput
Rated for sustained reads up to 530 MB/s and writes up to 500 MB/s.
Sustained random I/O
Rated up to 98,000 IOPS random read and 44,000 IOPS random write at 4 KB, QD32.
Enterprise-workload endurance
1,700 TBW is specified using the JESD219A enterprise workload.
Power-loss protection
Protection is specified to help safeguard in-flight data during an unexpected power interruption.
DSM drive management
Synology integration supports workload-based lifetime analytics and streamlined firmware maintenance in validated deployments.
Five-year limited warranty
Coverage applies for five years or until the specified endurance is reached, whichever comes first.
Who is the Synology SAT5220-960G best for?
A strong choice for
- Compatible Synology systems requiring a 960 GB enterprise SATA SSD
- Mixed and intensive 24/7 storage workloads
- Applications that benefit from stable sustained I/O
- Administrators wanting Synology-validated drive media
- Deployments that value DSM-based drive monitoring
Consider another model if you need
- The target Synology system does not list this exact model as compatible
- You need M.2 NVMe rather than a 2.5-inch SATA SSD
- You require a capacity other than 960 GB
- You need portable external storage
