40863131 Seagate Exos X24 20TB SATA 512 MB 3.5" Server HDD

High-Density 3.5-Inch Enterprise HDD Storage with the 40863131 for Capacity-Focused Tiers

The 40863131 is a 20TB 3.5-inch internal enterprise HDD designed for capacity-oriented server and workstation storage where predictable latency and sustained throughput are required. Built on a SATA 6Gb/s single-port interface, the 40863131 integrates cleanly into mainstream RAID controllers and JBOD shelves, enabling cost-efficient scale-out storage tiers without introducing host-side platform constraints.

Using CMR recording at 7200 RPM with a 512MB cache, the 40863131 supports stable write behavior under mixed workloads that can penalize SMR-based designs, making it well-suited for rebuild-sensitive RAID sets and large nearline pools. Dual sector format support (512e and 4Kn) simplifies alignment with modern operating systems and object storage stacks, while maintaining compatibility with legacy environments. In dense enclosures, the 40863131 provides a pragmatic balance between IOPS per watt and raw capacity, optimizing rack-level terabytes for backup, archive, and nearline object repositories.

Why Choose the 40863131?

The 40863131 targets enterprise deployments that prioritize capacity density, operational consistency, and long service life across scale-out architectures. With a 2.5 million hour MTBF profile and efficient power characteristics, the 40863131 supports predictable fleet behavior in multi-drive arrays, reducing operational risk during continuous ingest, background verification, and recovery workflows.

Seagate engineers the Exos platform with an emphasis on durability under sustained duty cycles, predictable thermal operation in high-density chassis, and integration alignment with modern data center storage standards. This approach helps infrastructure teams standardize on qualified drive tiers while maintaining compatibility across RAID, HBA, and software-defined storage designs.

Key Applications:

• Backup and restore repositories
• Archive and compliance storage
• Nearline object storage tiers
• Scale-out NAS capacity pools
• High-density JBOD expansion
