ST2000NM004A Seagate Exos 7E8 2TB SAS 256 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD featuring CMR nearline efficiency with the ST2000NM004A

The ST2000NM004A is a 3.5in enterprise HDD engineered for dense SAS storage shelves, rack servers, and shared storage arrays where predictable latency and sustained throughput matter more than burst IOPS. Integrated into modern x86 CPU platforms through 12Gb/s SAS backplanes and host bus adapters, it supports scalable drive counts and consistent behavior under queue depth, making it a practical building block for capacity-focused tiers.

With CMR recording and 4Kn media with 512e compatibility, the ST2000NM004A aligns well with RAID controllers, HBA pass-through designs, and software-defined storage stacks that prioritize rebuild stability and data layout efficiency. Its cache architecture and 7200 RPM profile support steady sequential workloads, while Protection Information (PI) enables end-to-end data integrity across the SAS path. PowerChoice and environmental sensing assist with energy governance in multi-node deployments.

Why Choose the ST2000NM004A?

The ST2000NM004A is optimized for high drive-density environments that require 24x7 operation, controllable power behavior, and predictable RAID tier performance. For capacity expansion in storage arrays and server-based repositories, the ST2000NM004A provides a balanced density-to-throughput profile with enterprise-class reliability targets and a straightforward scaling model across large volumes.

Seagate designs the Exos nearline family with an engineering focus on sustained duty cycles, firmware behavior aligned to data centre workloads, and qualification for modern SAS infrastructures. The ST2000NM004A reflects this approach with integrity features, longevity targets, and operational telemetry suited to standardized rack and enclosure architectures.

Key Applications:

• Data centre bulk storage tiers
• RAID capacity pools
• Backup repositories
• Nearline and archival storage
• Server and storage arrays
