ST32000NM004K Seagate Exos M 32TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Nearline SATA Enterprise HDD featuring helium-sealed CMR architecture with the ST32000NM004K

The ST32000NM004K is a 32TB Seagate Exos 3.5in internal nearline HDD engineered for high-capacity tiers in modern server and JBOD platforms. It aligns with scale-out storage nodes where CPU and memory resources are optimized for throughput and metadata handling rather than compute acceleration, and where predictable block storage performance is required across large drive counts.

With a SATA interface for broad backplane compatibility, the ST32000NM004K supports dense PCIe-based storage architectures indirectly by freeing PCIe lanes for NVMe caching or fabric adapters while bulk data resides on cost-efficient nearline media. CMR recording and a 512e format (4Kn with emulation) enable consistent write behavior across RAID, erasure coding, and object storage stacks, while the 512MB cache and up to 285MB/s sustained transfer help maintain rebuild and ingest windows in multi-disk pools.

Why Choose the ST32000NM004K?

The ST32000NM004K delivers a pragmatic density-to-performance balance for 24x7 duty cycles, enabling capacity growth without increasing rack footprint or enclosure count. Designed for enterprise reliability at scale, it supports predictable fleet operations in mixed workloads such as backup streams, large-object repositories, and content storage where sustained throughput and serviceability matter more than low-latency IOPS.

Seagate designs the Exos family with data center lifecycle requirements in mind, combining helium-sealed mechanics with advanced areal density technology and power management features to support consistent thermals and operational efficiency. Security capabilities such as RSA-3072 firmware verification and Instant Secure Erase help align the ST32000NM004K with controlled decommissioning processes and platform integrity expectations.

Key Applications:

• High-density nearline storage in servers and JBODs
• Backup and recovery repositories
• Archive and long-retention data pools
• Scale-out object and content storage
• Capacity tiers behind NVMe cache
