Enterprise-Class Endurance and Performance Built Specially for Synology NAS Systems
Maximize your network storage capabilities with the Synology SAT5221 960GB SATA III 2.5" Internal SSD. Purpose-built to handle relentless 24/7 server environments, this enterprise-grade solid-state drive targets mission-critical applications like online transaction processing (OLTP) databases, multi-tenant virtualization deployments, and demanding high-speed SSD caching configurations.
The SAT5221-960G guarantees highly sustained, steady-state input/output performance while significantly slashing latency for your data infrastructure. By using hardware tightly synchronized with Synology’s operating architecture, you safeguard your business setup with seamless operation and zero service interruption.
Key Technical Features
- Sustained High Performance: Reaches steady-state read and write speeds up to 500 MB/s alongside 90,000 IOPS random reads to satisfy demanding corporate virtualization networks.
- Enterprise Endurance Profile: Engineered to process heavy mixed data writes with a staggering baseline endurance ranking over 1,700 TBW (Terabytes Written) under intense JESD219A workloads.
- Advanced Power Loss Protection (PLP): Built with an onboard array of specialized industrial capacitors that store auxiliary juice to flush all data-in-flight into non-volatile NAND blocks if the main power suddenly drops.
- End-to-End Data Integrity: Integrates robust end-to-end circuit protection pathways that completely insulate your corporate file structures from data corruption risks at every phase of transfer.
- Deep Storage Analytics via DSM: Complete integration inside Synology DiskStation Manager (DSM) permits precision lifetime tracking of each SSD block relative to your actual server workloads.
- Effortless One-Click Upgrades: Avoid complex manual storage upgrades; receive automatic firmware notifications directly inside DSM and trigger installations in a single click.
