Product Overview
The Seagate ST2000NM0023 is a 2TB enterprise hard disk drive from the Constellation ES.3 product family. Designed for enterprise storage infrastructure, this 3.5-inch drive combines 7200RPM rotational speed, a 6Gb/s Serial Attached SCSI (SAS) interface, and a 128MB cache.
The drive is designed for capacity-oriented enterprise storage, including server storage arrays and compatible SAS-attached disk enclosures. Its dual-port SAS interface supports integration into enterprise storage architectures designed for SAS connectivity.
Storage Performance and Interface
The 7200RPM spindle speed and multi-segmented 128MB cache support sustained data access for enterprise storage workloads. The SAS interface supports link speeds of up to 6Gb/s, subject to the capabilities of the host controller and storage infrastructure.
The Constellation ES.3 platform incorporates enterprise-oriented features, including PowerChoice power management technology and Protection Information support for compatible storage environments.
Enterprise Storage Features
This model incorporates features intended for enterprise storage deployment, including dual-port connectivity, drive-level error correction, and mechanisms designed to support data integrity and controlled power consumption.
- Dual-port SAS connectivity: Supports compatible enterprise storage architectures with dual-port SAS infrastructure.
- Protection Information: Supports T10 Data Integrity Field functionality when used with compatible host systems and storage controllers.
- PowerChoice technology: Provides supported power-management options for compatible enterprise storage environments.
- Humidity sensing: Incorporates a humidity sensor as part of the drive's environmental monitoring features.
Compatibility and Deployment
The ST2000NM0023 is intended for systems supporting 3.5-inch SAS hard disk drives. Before installation, verify the storage controller, drive backplane, firmware, sector-format requirements, and available drive-bay space.
Although the interface supports SAS connectivity, physical fit alone does not guarantee compatibility. A system designed exclusively for SATA drives should not be assumed to support this SAS model.
Applications
- Enterprise server storage and data volumes.
- SAS-based storage arrays and disk enclosures.
- Capacity-oriented business storage systems.
- Compatible RAID configurations and enterprise data repositories.
Actual suitability depends on the workload, storage controller, system configuration, and application requirements.
DC Supplies Product Note
The ST2000NM0023 is the standard Constellation ES.3 model, not the similarly numbered self-encrypting ST2000NM0043 or Instant Secure Erase ST2000NM0113 variant. If replacing an existing drive, match the complete model number and confirm the controller's supported sector format before ordering.

Frequently Asked Questions
Is the ST2000NM0023 compatible with SATA drive bays?
No. This model uses a SAS interface. A SATA-only controller or backplane should not be assumed to support it. Check the server or storage enclosure documentation before installation.
Can this drive be used in a RAID array?
It can be used in compatible enterprise RAID environments. Verify support for this exact model, the required sector format, controller firmware, and the intended RAID configuration.
Does the ST2000NM0023 support hardware encryption?
The ST2000NM0023 is the standard model. The separately numbered ST2000NM0043 is the self-encrypting variant, while ST2000NM0113 is the Instant Secure Erase variant. Do not assume those additional security features are available on the standard model.
What should be checked before replacing an existing enterprise hard drive?
Confirm the exact part number, SAS interface, physical form factor, supported sector format, controller compatibility, and system firmware requirements. Also check whether the storage platform requires a manufacturer-approved drive model.
Is mounting hardware included?
The package contents have not been verified for this specific listing. Confirm the supplied accessories with the seller before ordering.
