Engineered for Demanding Enterprise Environments
The SAT5221 is built to excel in the most demanding professional environments. Whether you're running online transaction processing databases, virtualisation workloads, or intensive mixed I/O applications, this drive delivers consistently high performance with minimal service disruptions. The advanced power loss protection circuit ensures your data remains safe even during unexpected shutdowns, while end-to-end data protection safeguards integrity across the entire data path.
Exceptional Endurance and Performance
With a 2.5-inch 7mm form factor and SATA 6 Gb/s interface, the SAT5221 offers 960GB capacity for your most critical applications. Sequential read and write speeds of up to 500 MB/s ensure rapid data access, while random read performance reaches 90,000 IOPS and random write hits 30,000 IOPS (4KB, QD32). The drive's 1,700 TB TBW rating means it's built to withstand years of intensive 24/7 workloads without compromising performance or reliability.
Seamless Integration with Synology Systems
The SAT5221 is thoroughly validated for Synology systems following each engineering change, with strict management of firmware and component updates. Full integration with DiskStation Manager (DSM) enables lifetime analytics based on actual workloads, timely notifications for proactive maintenance, and one-click firmware upgrades. This purpose-built design ensures optimal compatibility, reliability, and ease of management for Australian businesses and IT professionals.
Robust Operating Conditions
Designed for demanding environments, the SAT5221 operates reliably in temperatures from 0°C to 70°C and can be stored in conditions ranging from -40°C to 85°C. Power consumption is efficient with 2.3W during active reads, 3.2W during active writes, and just 1.3W when idle, making it suitable for power-sensitive enterprise deployments.
