Key Specifications

Storage Capacity and Form Factor

With 1 terabyte of storage space, this hard drive provides ample room for operating systems, applications, and data storage in enterprise environments. The capacity is optimized for RAID configurations and storage arrays where multiple drives work in concert to provide redundancy and improved performance.

3.5-Inch Low Profile Design

The drive features a standard 3.5-inch form factor with low-profile design considerations, ensuring compatibility with various server chassis and storage enclosures. The physical dimensions adhere to industry standards, measuring approximately 147mm x 101.6mm x 26.1mm, allowing for seamless integration into existing hardware infrastructure.

7200 RPM Spindle Speed

The 7200 revolutions per minute spindle speed enables faster data access times compared to lower-RPM drives. This higher rotation speed translates to reduced latency and improved overall system responsiveness, particularly important in multi-user environments and applications requiring frequent data access.

64MB Buffer Cache

Equipped with a 64MB DDR SDRAM buffer, the Dell 2T51W efficiently manages data transfers between the drive and host system. This substantial cache size helps improve performance by storing frequently accessed data and optimizing read/write operations, reducing the need for direct physical disk access.

SATA 6Gbps Interface

The Serial ATA 6Gbps interface provides maximum theoretical transfer rates of 600MB/s, though actual performance varies based on workload and system configuration. This interface maintains backward compatibility with SATA 3Gbps and SATA 1.5Gbps systems, ensuring broad compatibility across different generations of server hardware.

Advanced Features and Technologies

Data Integrity and Protection

The drive incorporates advanced error correction codes (ECC) to detect and correct data errors in real-time. This technology works in conjunction with the drive's firmware to ensure data integrity during both read and write operations, crucial for maintaining data accuracy in enterprise environments.

Vibration Resistance

Enterprise hard drives must operate reliably in multi-drive environments where vibration can impact performance. The Dell 2T51W includes advanced vibration compensation technologies that minimize the effects of both rotational and translational vibration, maintaining consistent performance even in densely populated server racks.

Advanced Power Efficiency

Despite its high-performance characteristics, the drive implements sophisticated power management features to optimize energy consumption. These include multiple power states that automatically adjust based on workload demands, helping to reduce overall power consumption in data center environments where energy costs are significant operational considerations.

Wide Compatibility

Server and Storage Systems

The Dell 2T51W is engineered for compatibility with Dell PowerEdge servers and PowerVault storage systems, though its standard SATA interface ensures broad compatibility with other manufacturers' equipment. The drive undergoes rigorous testing to ensure reliable operation in various server configurations and operating environments.

Low Profile With Tray Configuration

The "Low Profile With Tray" designation indicates that the drive includes or is designed for use with low-profile mounting hardware, facilitating installation in space-constrained environments. The tray system ensures proper mounting and alignment within server drive bays, promoting optimal airflow and vibration dampening.

Performance Metrics and Benchmarks

Sustained Transfer Performance

The drive delivers sustained data transfer rates appropriate for its class, with sequential read and write performance optimized for enterprise workloads. The combination of 7200 RPM spindle speed, high areal density, and SATA 6Gbps interface provides balanced performance for mixed workloads.

Random Access Performance

With average seek times typically under 9ms for reads and under 10ms for writes, the drive offers responsive performance for random I/O operations. These characteristics make it suitable for applications requiring frequent access to scattered data across the drive's surface.

Workload Performance

Annualized Workload Rating

Enterprise hard drives are rated for specific annual workload capacities, typically measured in terabytes written per year. The Dell 2T51W is engineered to handle the demanding workloads characteristic of server environments, though specific workload ratings should be verified against current documentation.

IOPS Capabilities

The drive's input/output operations per second (IOPS) performance varies based on workload characteristics, but generally provides appropriate performance for its class in enterprise environments. The 7200 RPM spindle speed and cache management contribute to its overall IOPS capabilities.

Use Cases and Applications

Primary Storage Applications

The 1TB capacity and performance characteristics make the Dell 2T51W suitable for use as a boot drive in servers, providing ample space for the operating system, hypervisor, and core applications while delivering the reliability required for server environments.

Data Storage and Archiving

With its balanced performance profile and capacity, the drive works well for general data storage applications in business environments. It can serve as primary storage for file servers, application servers, and other infrastructure components where reliability is paramount.

Storage Arrays and SANs

In storage area networks and dedicated storage arrays, multiple Dell 2T51W drives can be configured in RAID to provide both performance and redundancy. The drive's characteristics make it suitable for these implementations where multiple drives work in concert.
