Capacity and Form Factor Details

The 1.92TB usable capacity represents an optimized point in the capacity curve for enterprise storage, balancing performance, endurance, and cost-effectiveness. This specific capacity point is engineered to provide over-provisioning that enhances both performance consistency and drive longevity. The 2.5-inch form factor (15mm height) ensures compatibility with most enterprise server drive bays and storage enclosures, making it suitable for both new deployments and infrastructure upgrades.

Physical Dimensions 

Measuring 100.2mm x 69.85mm x 15mm and weighing approximately 120g, the drive conforms to standard 2.5-inch enterprise form factor specifications. The 15mm height accommodates the additional components required for enterprise-grade power-loss protection and enhanced thermal management, distinguishing it from consumer-grade 7mm SSDs.

Capacity Optimization Technology

HPE implements intelligent over-provisioning at the 1.92TB capacity point, reserving additional NAND for garbage collection, wear leveling, and background maintenance operations. This approach significantly improves write amplification factor and extends the drive's usable lifespan while maintaining consistent performance under varying workload conditions.

Interface and Protocol Performance

The Serial Attached SCSI (SAS) 12Gbps interface provides dual-ported connectivity, enabling multipath I/O configurations for high availability environments. This interface delivers full duplex communication with theoretical bandwidth of up to 1,200MB/s per direction, effectively eliminating interface bottlenecks for even the most performance-sensitive applications.

SAS 12Gbps Dual-Port Advantages

Dual-port SAS architecture provides redundant paths to the storage device, allowing continuous operation even if one host connection fails. This capability is essential for mission-critical applications requiring maximum uptime. The 12Gbps data rate represents a significant improvement over previous 6Gbps SAS generations, effectively doubling the available bandwidth for both read and write operations.

Backward Compatibility Features

While designed for SAS 12Gbps performance, this SSD maintains full backward compatibility with 6Gbps and 3Gbps SAS infrastructures. This ensures seamless integration into existing data center environments while providing a clear performance upgrade path as infrastructure evolves. The drive automatically negotiates the optimal connection speed with the host controller.

NAND Technology and Endurance

Utilizing enterprise-grade Triple-Level Cell (TLC) NAND flash, the VO001920RZWUR strikes an optimal balance between cost, capacity, and endurance. HPE enhances raw TLC NAND through advanced controller technology, sophisticated wear-leveling algorithms, and substantial over-provisioning to deliver enterprise-class reliability that meets the demands of 24/7 operation.

TLC NAND with Enterprise Enhancements

The TLC NAND architecture stores three bits per cell, providing higher density and more cost-effective storage compared to SLC and MLC alternatives. HPE's implementation includes advanced signal processing, strong error correction codes, and sophisticated read-retry algorithms to maintain data integrity throughout the drive's operational lifespan.

Write Endurance Specifications

As a read-intensive drive, the VO001920RZWUR is rated for 0.8 Drive Writes Per Day (DWPD). This translates to approximately 2.8 Petabytes Written (PBW) total endurance, sufficient for most read-centric workloads while providing adequate write capability for metadata updates, logging, and background operations.

Data Retention Characteristics

The drive maintains data integrity for up to 3 months at 40°C under worst-case storage conditions following its rated endurance consumption. This exceeds JEDEC enterprise SSD requirements and ensures data preservation during maintenance windows, disaster recovery scenarios, or equipment redeployment cycles.

Performance Metrics and Capabilities

Engineered specifically for read-intensive applications, the VO001920RZWUR delivers exceptional random read performance up to 180,000 IOPS and sequential read speeds up to 1,100 MB/s. Write performance is optimized for consistency rather than peak throughput, with capabilities exceeding typical read-intensive workload requirements.

Mixed Workload Capability

While optimized for read-intensive applications, the drive competently handles mixed workloads with read/write ratios up to 80/20. This flexibility allows deployment in environments where workload characteristics may vary or evolve over time, providing investment protection as application demands change.

Reliability, Availability, and Serviceability Features

With a rated MTBF of 2,000,000 hours and an annualized failure rate of 0.44%, the VO001920RZWUR delivers exceptional reliability for enterprise deployment. The drive includes comprehensive power-loss protection, end-to-end data path protection, and advanced telemetry capabilities for proactive health monitoring.

Data Protection Mechanisms

Multiple layers of data protection ensure integrity from the host interface to the NAND media. These include T10 DIF (Data Integrity Field) support, advanced ECC with LDPC (Low-Density Parity Check) coding, and RAID-style parity protection within the NAND array itself. These technologies work together to provide unprecedented data integrity for enterprise applications.

Power-Loss Protection Implementation

A comprehensive power-loss protection system includes both immediate and holdup power circuits that provide sufficient energy to complete in-progress writes and commit data from volatile caches to non-volatile storage. This protection extends across all power loss scenarios, including sudden power removal, brownout conditions, and controlled shutdown sequences.

HPE Platform Integration Benefits

When deployed in HPE servers, the drive benefits from enhanced management through HPE iLO and OneView, automated firmware updates through HPE Service Pack for ProLiant, and optimized performance through HPE Smart Array and HPE HBA controllers. This deep integration simplifies operational management and ensures optimal performance characteristics.

Environmental Specifications and Power Metrics

Designed for data center deployment, the drive operates within standard enterprise environmental parameters while optimizing for power efficiency. Typical power consumption during active operation is 6-8 watts, with idle power as low as 1.5 watts, contributing to overall data center power efficiency.
