HPE 764904-B21 400GB PCI-E 3.0 NVMe RI MLC 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-class applications where read-intensive workloads dominate. Leveraging Non-Volatile Memory Express (NVMe) technology, this SSD offers exceptional latency reduction and rapid input/output operations per second (IOPS), enabling seamless data retrieval for critical business applications. Built using Multi-Level Cell (MLC) NAND flash, it delivers a balanced combination of endurance, reliability, and cost-effectiveness tailored for high-demand storage environments.

Key Features of HPE 764904-B21 SSDs

This SSD category includes several essential attributes that make it a preferred choice for enterprise storage systems. These drives offer PCI Express 3.0 x4 interface connectivity, which provides a substantial throughput advantage over legacy SAS and SATA storage devices. The 2.5-inch form factor ensures compatibility with a wide range of HPE ProLiant servers, enabling easy integration into existing infrastructure. Optimized for read-intensive workloads, these drives can handle a vast number of read operations while maintaining minimal latency.

NVMe Technology for High-Performance Storage

NVMe protocol utilization in the HPE 764904-B21 series reduces command overhead significantly compared to traditional storage protocols like SAS or SATA. By enabling multiple queues and parallelized access to the NAND flash memory, NVMe technology maximizes the SSD's potential to deliver low-latency and high-throughput performance. Enterprise workloads, such as database query retrieval, virtualization environments, and analytics applications, benefit from NVMe's reduced I/O wait times, resulting in faster access to critical data and improved overall system efficiency.

Endurance and Reliability with MLC NAND Flash

MLC NAND flash used in the HPE 764904-B21 ensures a dependable balance between performance and endurance. While Single-Level Cell (SLC) NAND may offer higher endurance, MLC technology provides a cost-effective solution for applications primarily focused on read operations. The read-intensive nature of these SSDs aligns perfectly with workloads that predominantly require high-speed data access without excessive write cycles, extending the lifespan of the drive and reducing operational costs.

Optimized Read-Intensive Performance

Designed for environments where reading data outweighs writing, the HPE 764904-B21 excels in scenarios such as large-scale databases, analytics platforms, and virtual desktop infrastructure (VDI). These drives can sustain high read throughput while maintaining minimal latency, making them ideal for performance-critical workloads. The consistent read performance ensures that multiple concurrent applications can access data simultaneously without bottlenecking system resources.

Integration with HPE ProLiant Servers

The 2.5-inch U.2 form factor of the HPE 764904-B21 guarantees broad compatibility with HPE ProLiant Gen9 and Gen10 servers. These SSDs are validated and tested extensively within HPE environments to provide seamless integration, optimal firmware compatibility, and predictable performance. IT administrators benefit from simplified deployment and maintenance, ensuring that storage solutions operate reliably within enterprise systems without requiring complex configuration or custom adapters.

Advanced Data Integrity and Security Features

Data integrity and security are vital for enterprise storage solutions. The HPE 764904-B21 employs advanced error correction algorithms to detect and rectify potential data corruption, ensuring the accuracy of read operations. End-to-end data protection mechanisms help safeguard critical information, while optional encryption capabilities allow organizations to secure sensitive data. These features are particularly important for regulatory compliance and risk management in enterprise IT environments.

Scalability and Storage Architecture Considerations

When deploying multiple HPE 764904-B21 SSDs, scalability becomes a key advantage. These NVMe drives can be clustered in storage arrays or integrated into hybrid storage architectures alongside SAS and SATA drives. By strategically combining read-intensive SSDs with higher-capacity write-optimized drives, organizations can achieve a balance of performance and storage capacity tailored to their workloads. This approach ensures efficient utilization of storage resources while optimizing cost-effectiveness.
