Analytics
- Actionable insight for optimal performance and longevity

Updates
- One-click drive firmware updates through DSM4

Stable high performance for demanding environments
- Engineered for demanding environments such as for online transaction processing (OLTP) databases and virtualization deployments, Synology SAT5200 Series drives deliver consistently high performance.

11,460 TBW
- Built to withstand 24/7 intensive workloads with endurance up to 11,460 TBW.

End-to-end data protection
- Data integrity and consistency are safeguarded over the entire data transfer path.

Power loss protection circuit design
- Dedicated capacitors provide sufficient power to flush data-in-flight into NAND flash during a power loss event, further preventing data corruption.

Better analytics
- Full integration with Synology DiskStation Manager (DSM) enables lifetime analytics for each SAT5200 Series drive based on actual workloads.

Timely notifications
- Plan further ahead for uninterrupted system performance and longevity with timely notifications.

Optimal use
- Easy monitoring allows you to make optimal use of each SSD.

One-click firmware upgrades
- Automatic firmware update notifications and one-click installation through DSM minimize maintenance workload and reduce the chance of oversights.

Purpose-built for Synology systems
- Synology SAT5200 Series SSDs are thoroughly validated for our systems following each engineering change, while firmware and component changes are strictly managed. Intensive I/O stress, power cycling, and temperature trials ensure that all products meet our strictest standards for quality and reliability.
