ST22000NM001E Seagate Exos X22 22TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Datacenter HDD for Nearline and Scale-Out Storage with the ST22000NM001E

The ST22000NM001E is a 22TB 3.5in internal datacenter HDD engineered for capacity-driven server and JBOD tiers where predictable throughput, sector-format flexibility, and long service life matter more than low-latency flash. In modern storage nodes built on current x86 CPU platforms, the ST22000NM001E complements high-core-count processing and large DRAM caches by providing economical bulk persistence for backup sets, object stores, and content repositories without compromising on deterministic write behavior.

Using SATA single-port connectivity, the ST22000NM001E aligns with widely deployed HBA and expander topologies on PCIe-based storage servers, enabling straightforward scaling across dense 4U/5U enclosures. CMR recording and a 7200 RPM design support consistent sequential performance for rebuilds and ingest, while Advanced Format support (4Kn and 512e) helps standardize sector size across mixed OS, hypervisor, and storage software stacks to reduce alignment overhead and avoid translation penalties.

Why Choose the ST22000NM001E?

The ST22000NM001E provides a strong density-to-bay ratio for nearline architectures, allowing storage engineers to increase usable capacity per chassis while maintaining enterprise reliability targets. With a helium-sealed design, sustained transfer capability, and 2.5M hours MTBF, the ST22000NM001E is suited for scalable deployments where operational consistency, controlled power draw, and predictable servicing cycles are essential.

Seagate designs Exos-class drives to meet datacenter duty cycles, focusing on mechanical stability, firmware behavior under sustained workloads, and compatibility with common RAID, erasure coding, and JBOD management stacks. This engineering approach supports modern data centre standards for high-capacity tiers and long retention policies.

Key Applications:

• High-capacity nearline storage tiers
• Backup and archive repositories
• Scale-out object storage
• Content repositories
• General-purpose server and JBOD HDD pools
