Silver 3.5 inch enterprise hard drive with circuit board visible

Seagate

Seagate ST2000NM0055 2TB 7200RPM 128MB 3.5" SATA Enterprise internal hard drive

SKU CH-W9D1-1E43G

Enterprise-grade 2 TB hard drive with 7200 RPM speed and 128 MB cache for 24×7 bulk-data workloads

  • 2TB capacity for bulk-data storage
  • 7200RPM spindle speed for responsive data access
  • 128MB cache to accelerate read/write operations
  • SATA III 6Gb/s interface for broad system compatibility
  • Enterprise-grade design with enhanced error correction and rotational vibration tolerance

Enterprise capacity for bulk data

The Seagate ST2000NM0055 is a 2000 GB 3.5 inch enterprise hard drive built for 24x7 operation in RAID arrays and bulk-storage servers. Its 7200 RPM spindle and 128 MB cache serve capacity-optimised workloads that demand consistent throughput over peak speed.

Thermals and power in normal use

Low power consumption and on-demand Power Choice technology based on T10/T13 standards reduce heat output during idle periods while maintaining 24x7 reliability. Enhanced error correction and super parity protect data integrity without adding measurable acoustic or thermal load.

Bundled firmware and encryption options

Multi-drive firmware is tuned for enterprise RAID availability, and the product family includes self-encrypting and FIPS 140-2 validated variants for deployments that require hardware-based data protection.

Questions about this item

How do I install the 3.5 inch SATA drive in a desktop and what step is often missed?

Mount the 3.5 inch drive in a bay, connect the SATA data cable to the motherboard and the SATA power cable from the PSU, then enable the SATA port in BIOS if it is disabled by default.

What maintenance or replacement will the 7200RPM enterprise drive need later?

The 7200RPM enterprise drive has no user-serviceable parts; monitor SMART attributes for reallocated sectors and replace the unit when the drive reports a pre-fail warning.

What limit appears first on the 2TB SATA III drive during sustained 24x7 workloads?

The 128MB cache and 6Gb/s SATA III interface set the sustained throughput ceiling, while rotational vibration tolerance maintains consistency under multi-drive RAID loads.
