Features:
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.

Enterprise-grade endurance and reliability

- Up to 10,000 TBW
Built to withstand 24/7 intensive workloads with endurance up to 10,000 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.
