ST30000NM004K Seagate Exos M 30TB SATA 512 MB 3.5" Server HDD

High-Capacity 3.5in Enterprise SATA HDD for nearline scale-out storage with the ST30000NM004K

The ST30000NM004K is a 30TB 3.5in internal enterprise HDD engineered for capacity-optimised tiers where CPU and GPU resources are secondary to predictable, sustained throughput and efficient rack-level density. In modern server platforms, the ST30000NM004K aligns with x86 virtualization hosts and storage nodes by keeping memory and compute dedicated to caching, deduplication, and metadata services while the drive delivers cost-effective bulk capacity at 7200RPM.

Designed for SATA backplanes and single-port connectivity, the ST30000NM004K integrates cleanly into PCIe-based storage architectures that rely on HBA or RAID controllers, enabling straightforward expansion without altering the compute complex. CMR recording and Advanced Format (4Kn with 512e emulation) support consistent write behavior for distributed file systems and backup targets, while 512MB cache helps smooth bursty I/O patterns common in object stores, archive tiers, and repository ingest. Security features such as Instant Secure Erase with RSA-3072 firmware assist with lifecycle governance in multi-tenant data centres.

Why Choose the ST30000NM004K?

The ST30000NM004K provides a strong density-to-performance profile for 24x7 nearline workloads, reducing drive count per usable PB while maintaining operational consistency in large fleets. With enterprise reliability design targets and hot-plug capable integration, the ST30000NM004K supports scalable deployment patterns from single-node backup servers to multi-rack Ceph or HDFS-class clusters.

Seagate designs the Exos M platform around predictable service characteristics, sustained duty cycles, and disciplined qualification for data centre thermals and vibration environments, helping standardise storage tiers across mixed server generations.

Key Applications:

• Nearline bulk storage tiers
• Backup and recovery repositories
• Archive and compliance retention
• Object storage nodes
• Distributed file systems (Ceph/HDFS class)
