ST4000NM006B Seagate Exos 7E10 4TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Enterprise SATA HDD for 24x7 Capacity Tiers with the ST4000NM006B

The ST4000NM006B is a 3.5in enterprise hard drive designed to anchor capacity tiers in rack servers and storage enclosures where predictable latency and sustained throughput matter more than ultra-low access times. In CPU-centric platforms—from modern x86 virtualization hosts to storage nodes fronted by PCIe NVMe cache—the ST4000NM006B integrates cleanly as a high-volume SATA layer that complements DRAM-backed page cache and SSD acceleration without inflating cost per TB.

Architecturally, the ST4000NM006B supports scale-out storage designs that rely on wide-drive counts, HBA-attached SATA backplanes, and resilient software stacks. CMR recording and 512n formatting help preserve consistent write behavior for RAID groups, erasure coding, and backup ingest, while a 256MB cache supports steady sequential streams common in nearline datasets. As expansion moves through PCIe Gen4/Gen5 for compute and NVMe, the ST4000NM006B remains an efficient capacity target behind controllers and expanders, keeping primary PCIe lanes available for GPUs, NICs, and flash.

Why Choose the ST4000NM006B?

The ST4000NM006B delivers a practical density-to-performance balance for enterprise fleets that need 24x7 duty-cycle operation and predictable serviceability at scale. It fits deployment logic where reliability, consistent media behavior, and secure data handling are required across large drive populations, enabling straightforward scaling in JBODs, RAID shelves, and multi-node storage clusters.

Seagate engineers the Exos line for data centre operating profiles, emphasizing sustained workload capability, controlled thermals, and qualification for enclosure interoperability. With Seagate Secure hardware encryption, the ST4000NM006B supports security policies that require data-at-rest protection without adding CPU overhead to the host.

Key Applications:

• Capacity tiering in rack servers and storage arrays
• Disk-based backup repositories
• Nearline bulk datasets and content libraries
• RAID and erasure-coded storage pools
