Overview
The Seagate ST31000524NS is a 1TB enterprise internal hard disk drive from the Seagate Constellation ES series. It uses a conventional magnetic recording design in a 3.5-inch form factor and is intended for compatible enterprise storage systems, servers, and workstations.
With a 7200 RPM spindle speed and a SATA interface, this drive provides mechanical storage for business data, file repositories, and compatible storage configurations. Its enterprise-oriented design includes rotational vibration tolerance and features intended to support continuous storage workloads.
Performance and Connectivity
The ST31000524NS uses a Serial ATA interface supporting transfer rates up to 3Gb/s. Its 32MB cache buffer supports drive operations, while the specified maximum sustained data transfer rate is up to 140 MB/s under the manufacturer's test conditions.
The drive supports Native Command Queuing and standard ATA transfer modes. Actual throughput depends on the workload, host controller, system configuration, and operating conditions.
Compatibility and Installation
This model is designed for systems with a compatible 3.5-inch SATA drive bay and a controller that supports SATA storage devices. Before installation, verify the system's supported drive capacities, interface requirements, mounting arrangement, and power connections.
- Interface compatibility: Requires a compatible SATA connection; the drive supports SATA transfer rates up to 3Gb/s.
- Physical installation: Requires a drive bay that accommodates a standard 3.5-inch internal hard drive.
- Power requirements: The drive uses +5V and +12V power rails.
- Enterprise system integration: Confirm the exact model is supported by the server or storage controller, particularly in RAID configurations.
A system designed exclusively for SAS drives should not be assumed to support this SATA model. Compatibility must be confirmed using the host manufacturer's documentation.
Key Features
- 1TB storage capacity: Provides internal storage for business files, applications, and data repositories.
- 7200 RPM rotation: Supports the performance characteristics of a conventional enterprise mechanical hard drive.
- SATA 3Gb/s interface: Connects to compatible SATA storage controllers.
- 32MB cache buffer: Provides onboard buffering for drive operations.
- Enterprise-oriented design: Incorporates rotational vibration tolerance and error-recovery features for supported storage environments.
Applications
- Server storage: Internal storage for compatible servers with SATA drive support.
- Business data repositories: Storage for documents, shared files, and operational data.
- Workstations: Additional storage in systems with compatible 3.5-inch SATA bays.
- Storage arrays: Potential use in compatible SATA-based storage configurations, subject to controller and system qualification.
DC Supplies Product Note
When replacing an existing enterprise drive, match the complete model number and interface rather than relying on capacity and physical size alone. The ST31000524NS uses SATA 3Gb/s connectivity and should not be confused with similarly named SAS models or desktop variants. For RAID deployments, verify the server or controller's compatibility list before selecting this drive.

Frequently Asked Questions
1. Is the Seagate ST31000524NS a SATA or SAS drive?
The ST31000524NS is a SATA hard drive with an interface transfer rate of up to 3Gb/s. It is not the SAS variant of the Constellation ES family.
2. Can this drive be installed in a desktop computer?
It may be used in a desktop computer that supports 3.5-inch SATA hard drives and provides the required power connections. Check the computer's drive-bay compatibility and controller support before installation.
3. Is this drive suitable for a server?
It is an enterprise-oriented hard drive intended for compatible storage environments. Confirm that the specific server supports this SATA model, especially if the system uses a RAID controller or has a manufacturer-qualified drive list.
4. Can this drive connect to a SATA 6Gb/s port?
The drive supports SATA transfer rates up to 3Gb/s. A compatible SATA controller may negotiate a supported lower interface speed, but the drive will not operate at 6Gb/s simply because the host port supports that rate.
5. Does the drive require a separate power connection?
Yes. The drive requires a compatible SATA data connection and a suitable power connection supplying the required +5V and +12V rails.
