ST3000NM0033

High-Performance 3.5-inch Enterprise SATA HDD featuring nearline CMR reliability with the ST3000NM0033

The ST3000NM0033 is a 3TB 3.5-inch enterprise hard drive engineered for always-on storage tiers in rack servers, RAID shelves, and SAN/NAS enclosures where predictable latency and sustained throughput matter more than burst performance. As a 7200 RPM CMR device with a 128MB cache and 512n sector format, the ST3000NM0033 aligns well with controller-based caching, write-back policies, and consistent rebuild behavior in mixed-drive arrays.

Designed for SATA 6Gb/s backplanes and standard HBA/RAID controller topologies, the ST3000NM0033 supports scalable expansion through dense drive bays and modular JBOD architectures. Power characteristics and PowerChoice capabilities enable more controlled thermal and energy profiles across multi-drive chassis, while data-path protections help maintain integrity through the host, controller, and media layers during continuous ingest, backup, and file service workloads.

Why Choose the ST3000NM0033?

The ST3000NM0033 provides a practical density-to-performance balance for nearline tiers, delivering enterprise reliability for 24x7 operation and predictable behavior under sustained duty cycles. Its CMR recording model supports consistent RAID parity operations, straightforward capacity planning, and scalable deployment across standard 3.5-inch storage nodes where serviceability and fleet uniformity are priorities.

Seagate designs the Constellation ES.3 family with an emphasis on long-life mechanics, validated firmware behavior, and compatibility with modern data centre standards for monitored operation. Enterprise features such as ECC, end-to-end data protection, S.M.A.R.T., and ramp load mechanisms are engineered to support dependable uptime and controlled maintenance windows at scale.

Key Applications:

RAID arrays and nearline SAN/NAS tiers
Backup repositories and archival staging
Log, telemetry, and data capture pipelines
General purpose file services
Always-on storage enclosures
