ST22000NM004E Seagate Exos X22 22TB SAS 512 MB 3.5" Server HDD

High-Density 3.5" Enterprise SAS Nearline HDD featuring CMR integrity with the ST22000NM004E

The ST22000NM004E is a 3.5" internal enterprise HDD engineered for bulk-capacity tiers in modern scale-out NAS/SAN designs, where predictable latency and sustained sequential throughput matter more than peak IOPS. As a 22TB, 7.2K SAS nearline drive, the ST22000NM004E supports balanced node architectures that pair multi-core server CPUs with high memory bandwidth and cache-centric RAID/HBA controllers to keep large data streams aligned to write-back policies.

In storage shelves and dense JBOD arrays, the ST22000NM004E fits PCIe-attached SAS HBAs and expander backplanes commonly deployed in 2U/4U platforms, enabling straightforward capacity scaling without changing the compute layer. CMR recording maintains consistent write behavior under rebuild and backup windows, while support for 512e/4Kn sector formats and adjustable logical sector size simplifies integration across mixed OS and hypervisor stacks. Helium-filled mechanics, humidity sensing, and PowerChoice/PowerBalance help control power and thermals per rack, supporting sustained 24/7 duty cycles.

Why Choose the ST22000NM004E?

The ST22000NM004E delivers a pragmatic density-to-cost profile for enterprise capacity tiers while maintaining operational safeguards expected in always-on arrays. With 2.5M hours MTBF and SAS enterprise signaling, the ST22000NM004E is suited to scalable deployments where predictable rebuild behavior, fleet standardization, and shelf-level serviceability drive uptime.

Seagate designs the Exos platform with an emphasis on data center reliability engineering, including fleet-ready firmware behavior, long-life mechanical design, and features aligned to modern storage standards such as Protection Information (PI) and Instant Secure Erase (ISE) for controlled data handling.

Key Applications:

• Scale-out NAS/SAN capacity tiers
• High-density HDD shelves and JBOD arrays
• Backup repositories and recovery targets
• Archive and cold-to-warm data lakes
• Sequential media and dataset storage
