ST3500514NS Seagate Constellation ES 0.5TB SATA 32 MB 3.5" Server HDD

Enterprise 3.5-inch SATA HDD featuring CMR RAID readiness with the ST3500514NS

The ST3500514NS is a 3.5-inch enterprise HDD designed to deliver predictable rotational-latency performance and consistent write behavior for general-purpose server platforms and storage appliances. In deployments where CPU and memory resources are optimized for throughput rather than compute acceleration, the ST3500514NS provides stable block storage to keep OS volumes, logging tiers, and bulk datasets responsive under sustained I/O.

Using a SATA interface for broad backplane compatibility, the ST3500514NS integrates cleanly into mixed-drive shelves and dense rack servers while maintaining deterministic characteristics through CMR recording. Its 32MB cache supports command queuing and burst handling, and the 7200RPM profile aligns well with RAID arrays where rebuild time and write consistency matter. The ST3500514NS is suited to PCIe expansion strategies that prioritize HBA-based scale-out and storage density over direct-attached NVMe, enabling cost-controlled capacity tiers without compromising 24x7 duty expectations.

Why Choose the ST3500514NS?

The ST3500514NS offers an efficient density-to-performance ratio for enterprise SATA tiers, balancing predictable behavior with operational resilience in always-on environments. For architects building scalable RAID sets, NAS shelves, or SAN tiering pools, the ST3500514NS supports straightforward fleet standardization, consistent provisioning, and reliable long-term service characteristics.

Seagate designs the Constellation enterprise line with a focus on sustained workload stability, qualification for continuous operation, and compatibility with modern data center storage standards. With an MTBF rating of 1.2M hours, the ST3500514NS aligns with reliability targets expected for shared infrastructure and controlled maintenance windows.

Key Applications:

• RAID arrays in rack servers
• NAS/SAN capacity tiering
• Backup and archive storage pools
• General-purpose 24x7 server storage
