ST22000NM000E Seagate Exos X22 22TB SAS 512 MB 3.5" Workstation HDD

High-Capacity 3.5-inch Enterprise SAS HDD featuring CMR helium design with the ST22000NM000E

The ST22000NM000E is a 22TB 3.5-inch enterprise HDD engineered for SAS server and storage platforms that prioritise predictable latency and high drive-count density. In tiered architectures, ST22000NM000E supports bulk capacity pools behind compute nodes and storage controllers, where CPU resources are reserved for data services while the drive layer delivers consistent sequential throughput and stable rebuild behaviour.

With a 7,200 RPM mechanism and large cache, ST22000NM000E is optimised for sustained streaming I/O patterns common to backup, object storage, and distributed file systems. The single-port SAS interface aligns with scale-out enclosures and JBOD designs, while 4Kn native support and 512e compatibility simplify integration across mixed operating system generations and storage stacks without compromising alignment strategy. Hardware-based SED encryption keeps security controls close to the media, reducing CPU overhead on host platforms and enabling standardised key management across fleets.

Why Choose the ST22000NM000E?

ST22000NM000E is suited to high-density deployments where the primary architectural goal is maximum usable TB per rack unit with enterprise reliability for 24x7 duty cycles. Its helium-filled design and enterprise endurance profile support sustained operation in large populations, while SAS connectivity and sector-format flexibility make ST22000NM000E a scalable choice for consistent provisioning, maintenance windows, and predictable expansion planning.

Seagate designs Exos-class drives with a focus on data centre operational continuity, emphasising controlled thermals, firmware behaviour tuned for multi-drive environments, and validation aligned to modern storage enclosures and SAS backplanes. This engineering approach helps standardise lifecycle management and supports long-term platform consistency.

Key Applications:

• Data centre bulk storage
• Backup repositories
• Archive and compliance retention
