HPE 764904-B21 400GB PCI-E 3.0 x4 NVMe SFF SSD Overview

The HPE 764904-B21 400GB PCI-E 3.0 x4 NVMe Read Intensive 2.5-inch Internal MLC SSD represents a high-performance storage solution designed for enterprise-grade servers and data centers. With an emphasis on read-intensive workloads, this NVMe SSD delivers consistent speed, reliability, and energy-efficient operation. Built with multi-level cell (MLC) NAND technology, it ensures a balance between endurance, performance, and cost efficiency, making it ideal for applications that require frequent data retrieval and minimal latency.

Advanced NVMe Interface and Performance Capabilities

This SSD leverages the PCI-E 3.0 x4 interface, providing high bandwidth and low latency communication with the host system. The NVMe protocol optimizes input/output operations per second (IOPS) and reduces CPU overhead, enabling faster access to large datasets and database queries. Enterprises benefit from predictable and scalable performance, particularly in virtualization environments, high-speed caching, and read-intensive transactional applications.

Read-Intensive Optimization

Specifically designed for read-intensive workloads, the HPE 764904-B21 SSD offers excellent sequential and random read performance. The architecture supports heavy read operations while maintaining low latency, ensuring critical applications operate smoothly. The drive is optimized for analytics, content delivery, and other scenarios where data retrieval speed outweighs write volume, offering a cost-effective solution without sacrificing reliability.

Sequential and Random Read Performance

The sequential read speeds of this 2.5-inch NVMe SSD deliver rapid throughput for large file transfers, while random read performance ensures quick access to scattered data blocks. This dual capability enhances system responsiveness and reduces wait times for demanding applications, allowing IT infrastructures to maintain high efficiency and user satisfaction.

Reliability and Endurance

HPE's engineering ensures that the 764904-B21 model provides robust reliability and consistent operation over extended periods. Built with MLC NAND, the SSD offers higher endurance than TLC solutions, supporting intensive read operations without compromising data integrity. Enterprise-class error correction codes (ECC) and wear-leveling algorithms further enhance the lifespan and prevent premature failures, ensuring uninterrupted performance in mission-critical environments.

Optimized for HPE ProLiant Servers

HPE 764904-B21 SSDs are fully compatible with HPE ProLiant Gen10 and Gen10 Plus servers, ensuring seamless integration and enhanced system reliability. The drives are designed to leverage HPE Smart Array controllers and HPE Smart Storage firmware, enabling advanced monitoring, predictive failure analysis, and simplified deployment. This tight integration ensures that enterprises can achieve maximum performance and operational efficiency while maintaining robust data protection mechanisms.

MLC NAND Technology Benefits

Multi-Level Cell (MLC) NAND technology stores two bits per cell, providing a strategic balance between endurance, cost, and storage density. In the HPE 764904-B21 SSD, this technology delivers sufficient write cycles for read-intensive workloads while optimizing storage capacity. MLC is particularly suitable for enterprise environments where frequent reads are common but writes are relatively moderate. This ensures a longer operational lifespan and reduced maintenance costs.

Scalability and Deployment Flexibility

These NVMe SSDs are designed to scale efficiently across diverse enterprise infrastructures. Whether deployed in high-density server configurations, storage arrays, or hyper-converged systems, the HPE 764904-B21 can accommodate growing performance demands without bottlenecks. Its compact 2.5-inch form factor ensures compatibility with standard drive bays, allowing for flexible deployment in both new and existing server environments.
