High-Performance 3.5in Enterprise SATA HDD for boot and tiered storage with the ST1000NM0055
The ST1000NM0055 is a 1TB 3.5in enterprise hard drive engineered for predictable latency in server boot volumes and tiered storage layers where cost-efficient capacity must remain operationally stable. In CPU-dense platforms and virtualized hosts, the ST1000NM0055 supports consistent OS, hypervisor, and utility partition behavior while leaving PCIe lanes and NVMe bays reserved for high-IO tiers.
Designed for SATA 6Gb/s backplanes, the ST1000NM0055 integrates cleanly into RAID controllers and SATA-based JBOD shelves with single-port connectivity and 512n sector formatting to maintain broad compatibility across legacy and modern server generations. Its 7200RPM CMR recording and 128MB cache provide steady sequential throughput for bulk data movement, log staging, and archival workflows, while Advanced Format support enables smoother alignment in mixed-disk pools and migration projects.
Why Choose the ST1000NM0055?
The ST1000NM0055 delivers a balanced density-to-performance profile for infrastructures that standardize on large counts of SATA bays, where consistent behavior and serviceability matter more than peak IOPS. With 24x7 duty suitability and 2.0M hours MTBF, the ST1000NM0055 is positioned for scalable deployments in mirrored boot sets, tiered storage groups, and capacity pools where operational risk must be controlled across many drives.
Seagate designs the Exos series around disciplined mechanical tolerances, firmware tuned for multi-drive environments, and validation aligned with modern data centre requirements for reliability, thermal operating ranges, and lifecycle continuity. This engineering focus helps the ST1000NM0055 remain dependable within standard monitoring, replacement, and RAID rebuild processes.
Key Applications:
- Data centre server boot volumes
- SATA-based JBOD and RAID capacity pools
- Tiered storage cold and warm tiers
- Workstation bulk storage
