Synology SAT5200 Series SATA SSDs offer stable I/O performance while reducing the latency of critical services and applications. They are built to handle mixed and intensive 24/7 workloads without compromising on endurance, providing a streamlined storage experience on Synology systems with minimal service disruptions.

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
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.
