ST31000524NS Seagate Constellation ES 1TB SATA 32 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SATA HDD featuring 24x7 CMR reliability with the ST31000524NS

The ST31000524NS is a 3.5in internal enterprise HDD designed for dependable capacity tiers in server and workstation platforms where SATA backplanes and proven RAID controllers define the storage architecture. As a 7200RPM CMR drive with 512n sectors, it aligns with predictable write behavior and consistent latency under mixed IO, making it suitable for boot volumes, logging tiers, and general-purpose capacity where SSD is not required.

In typical x86 server designs, the ST31000524NS integrates cleanly behind SAS HBAs with SATA breakout or native SATA controllers, preserving PCIe lanes for NICs, GPUs, or NVMe expansion while keeping bulk storage on cost-efficient bays. The cache and rotational profile support steady-state throughput for sequential services and moderate random access patterns, while PowerChoice enables policy-based power control in dense enclosures to manage thermals and power budgets without redesigning the platform.

Why Choose the ST31000524NS?

The ST31000524NS provides a pragmatic density-to-performance balance for always-on enterprise deployments, combining CMR write consistency with an enterprise MTBF profile to support RAID-protected arrays and predictable rebuild behavior. For architects standardizing on 3.5in SATA tiers, the ST31000524NS scales efficiently across multi-bay chassis and simplifies qualification when uniform firmware and sector format are required across fleets.

Seagate engineers the Constellation ES family with a focus on sustained 24x7 operation, qualification for data centre duty cycles, and interoperability in common server backplanes. The ST31000524NS reflects this approach through reliability-oriented design targets and power management features aligned with modern rack-level efficiency constraints.

Key Applications:

• Server and workstation boot volumes
• SATA RAID arrays in rack servers
• General-purpose capacity tiers
• 24x7 always-on logging and monitoring
• Backup and archival staging
