P18426-B21 HPE SSD 1.92TB SATA 6GBPS RI SFF SC

HPE P18426-B21 1.92TB SSD for Read-Intensive Storage

The HPE P18426-B21 1.92TB SATA SSD represents a pinnacle of storage engineering designed specifically for read-intensive enterprise workloads. As part of Hewlett Packard Enterprise's comprehensive storage solutions portfolio, this drive delivers exceptional reliability, consistent performance, and seamless integration with HPE server infrastructure. Engineered for data centers requiring high-capacity, cost-effective storage with superior read performance, this SSD stands as an optimal solution for modern enterprise environments.

Read-Intensive SSD 

Read-intensive solid-state drives are specifically optimized for workloads where data retrieval operations significantly outnumber write operations. Unlike write-intensive or mixed-use drives that prioritize write endurance, read-intensive SSDs like the P18426-B21 deliver exceptional read performance while maintaining cost-effectiveness for applications where frequent data writing isn't the primary concern.

Key of Read-Intensive Workloads

Enterprise applications generating predominantly read operations include web serving, content delivery networks, data analytics queries, virtual desktop infrastructure (VDI) boot images, and database query operations. These workloads benefit tremendously from the fast random read performance and consistent latency that the HPE P18426-B21 provides.

Capacity and Form Factor

1.92TB Usable Capacity

The 1.92TB capacity point represents an optimal balance between storage density and performance. This capacity provides ample space for enterprise applications while maintaining consistent performance characteristics across the entire storage array. The drive utilizes over-provisioning to ensure sustained performance and extended lifespan.

SFF (Small Form Factor) Design

The 2.5-inch Small Form Factor (SFF) design enables high storage density in modern server platforms. This compact form factor allows organizations to maximize storage capacity within limited rack space, making it ideal for high-density server configurations and storage-optimized HPE ProLiant and Apollo systems.

Interface and Performance Metrics

SATA 6Gbps Interface

The Serial ATA (SATA) 6Gbps interface provides broad compatibility with existing server infrastructure while delivering sufficient bandwidth for most read-intensive applications. This interface ensures seamless integration with HPE Gen8, Gen9, Gen10, and Gen10 Plus servers without requiring specialized hardware or controllers.

Reliability Specifications

DWPD (Drive Writes Per Day)

Rated for 0.8 Drive Writes Per Day (DWPD) over a 5-year warranty period, this SSD provides adequate write endurance for read-centric workloads with occasional write operations. This endurance rating ensures the drive can handle typical write patterns in read-intensive environments without premature wear-out.

HPE Smart Storage Administrator Integration

The P18426-B21 seamlessly integrates with HPE Smart Storage Administrator (SSA), providing comprehensive management capabilities. This integration enables health monitoring, firmware updates, and performance optimization through a unified interface, simplifying storage administration across the enterprise.

HPE Server Compatibility

The P18426-B21 is rigorously tested and certified for compatibility across HPE's server portfolio, including ProLiant DL, ML, and BL series, Synergy compute modules, and Apollo systems. This comprehensive compatibility ensures optimal performance and reliability when deployed in HPE infrastructure.

Storage Array Integration

Beyond direct server attachment, this SSD integrates seamlessly with HPE storage arrays including MSA, Store Virtual, and Store Easy platforms. The drive's consistent performance characteristics and management capabilities make it an ideal choice for expanding existing HPE storage infrastructure.

HPE Mixed-Use SSDs

Compared to HPE mixed-use SSDs, the P18426-B21 offers better cost efficiency for read-dominant workloads while maintaining similar read performance characteristics. Organizations can achieve significant cost savings by selecting read-intensive drives for appropriate workloads rather than over-provisioning with more expensive mixed-use alternatives.

HPE Write-Intensive SSDs

Write-intensive SSDs provide higher endurance for write-heavy applications but command premium pricing. For environments where write operations represent less than 35% of total I/O operations, the read-intensive P18426-B21 delivers optimal value without compromising read performance.

Firmware and Management 

HPE provides regular firmware updates through the Service Pack for ProLiant (SPP), ensuring ongoing performance optimization, security enhancements, and compatibility maintenance. These updates are thoroughly tested within HPE's ecosystem to ensure reliability and stability.
