Sandisk WUS5EA176ESP7E4 Ultrastar DC SN655 SSD

The Sandisk WUS5EA176ESP7E4 Ultrastar DC SN655 is a high-performance solid-state drive designed for enterprise and cloud data centers that demand extreme reliability, speed, and endurance. Utilizing the latest PCIe Gen4 NVMe interface and the U.3 form factor, this SSD provides the perfect balance between high-capacity storage and ultra-low latency operations. The drive is engineered to meet the rigorous requirements of modern data-intensive workloads, offering exceptional sequential and random read/write speeds while maintaining consistent performance over time. With 7.68 terabytes of storage capacity, it is tailored for large-scale deployments where massive storage, security, and durability are paramount.

Next-Generation PCIe Gen4 Interface

The PCIe Gen4 interface of the WUS5EA176ESP7E4 significantly enhances throughput compared to previous generations, allowing for ultra-fast data transfer rates of up to 6800 MB/s sequential read speeds. This advancement ensures that latency-sensitive applications, including real-time analytics, database processing, and virtualization workloads, experience minimal delays. By leveraging the NVMe 1.4b protocol, the SSD efficiently handles command queues and parallel requests, resulting in superior input/output operations per second (IOPS) and optimized system performance.

U.3 Form Factor for Enterprise Deployment

The U.3 15mm form factor is a versatile design that provides maximum storage density while supporting hot-swappable configurations in enterprise servers and storage arrays. The form factor ensures compatibility with high-density server environments and scale-out storage systems, enabling IT administrators to integrate the WUS5EA176ESP7E4 seamlessly into existing infrastructure. Its durable construction and robust connectors guarantee reliable operation under continuous high-performance workloads, reducing downtime and maintenance costs.

TCG Ruby Security Integration

Security is a critical aspect of enterprise storage, and the WUS5EA176ESP7E4 incorporates TCG Ruby encryption to safeguard sensitive data at rest. This built-in security protocol provides hardware-based encryption, ensuring that data remains protected against unauthorized access without impacting performance. Organizations managing highly regulated workloads, financial systems, and confidential databases benefit from this integrated security, making the SSD an ideal choice for compliance-focused deployments.

Drive Performance and Endurance

Exceptional Sequential and Random Performance

One of the defining features of the Ultrastar DC SN655 series is its ability to deliver outstanding sequential read and write speeds. Sequential read speeds reach up to 6800 MB/s, while sequential write operations achieve 2000 MB/s, enabling rapid data movement across large files. Random performance is equally impressive, with up to 980,000 IOPS for read operations and 80,000 IOPS for random writes. These capabilities make the drive suitable for databases, virtualization environments, and applications with mixed workload profiles, ensuring consistent low-latency response under heavy load conditions.

Endurance and Reliability for Continuous Operation

The WUS5EA176ESP7E4 is engineered to sustain a drive write per day (DW/D), translating to high endurance levels that support long-term data retention and reliability. With a maximum of 14 petabytes written, the SSD withstands demanding write-intensive applications without compromising integrity or speed. Its sophisticated error correction algorithms and wear-leveling technology maintain data accuracy, while the robust controller design minimizes the risk of failures during continuous enterprise workloads. This level of endurance makes it an optimal solution for cloud infrastructures, big data analytics, and distributed database systems.

Power Efficiency and Operational Requirements

Optimized Power Consumption

Despite its high performance, the WUS5EA176ESP7E4 is designed with power efficiency in mind. It operates at typical power levels of 16 to 18 watts while maintaining peak performance, and consumes only 8 watts in idle mode. These efficiencies reduce operational costs, particularly in large-scale data centers where hundreds or thousands of drives are deployed simultaneously. The drive supports dual voltage requirements of +12V and +3.3V, offering flexible integration into various server and storage platforms.

Compatibility Across Platforms

The SSD is compatible with a wide range of operating systems including Windows, Windows Server, and Linux. This ensures seamless integration into enterprise environments and software-defined storage solutions.
