ST1000NX0423 Seagate Exos 7E2000 1TB SATA 128 MB 2.5" Server HDD

High-Density 2.5in Enterprise SATA HDD for 24x7 Server Storage with the ST1000NX0423

The ST1000NX0423 is a 1TB 2.5in SATA enterprise HDD designed to complement modern CPU-centric rack servers where compute and memory bandwidth are provisioned for virtualisation and service delivery, while cost-efficient, predictable block storage remains essential for OS and read-optimised datasets. In platforms using multi-core x86 CPUs with DDR4/DDR5 memory architectures, the ST1000NX0423 supports stable I/O queues for system volumes and application data without consuming PCIe lanes required for NICs, accelerators, or NVMe tiers.

Integrated into SATA backplanes and RAID controllers, the ST1000NX0423 provides a straightforward storage layer for mirrored boot pools, capacity-balanced RAID groups, and workstation scratch or reference libraries. Features such as NCQ and S.M.A.R.T. enhance command scheduling and health telemetry, while Seagate RAID Rebuild and PowerChoice help optimise rebuild behaviour and power policies across dense enclosures. With low idle and operating power, the ST1000NX0423 aligns with thermally constrained 2.5in drive bays and predictable serviceability.

Why Choose the ST1000NX0423?

The ST1000NX0423 delivers an effective density-to-performance profile for SATA infrastructure, enabling consistent deployment across mixed server and workstation fleets. Its 24x7 datacentre duty cycle and 2.0M-hour MTBF target reliability for always-on environments, while the single-port SATA design fits common enterprise backplanes and simplifies qualification for scale-out arrays.

Seagate engineers Exos-class HDDs with a focus on controlled acoustics, power management, and firmware behaviour under sustained load, supporting enterprise operational standards for monitoring, lifecycle management, and RAID-centric architectures.

Key Applications:

• Boot and OS volumes in rack servers
• Read-optimised application data
• RAID 1/5/6 arrays in SATA enclosures
• Workstation datasets and reference libraries
