Write performance maintains enterprise standards with random write capabilities up to 70,000 IOPS and sequential write speeds of 1,200 MB/s. These performance characteristics ensure responsive application performance even under heavy workload conditions.

Reliability and Endurance Features

TLC NAND with Advanced Management

The drive utilizes enterprise-grade TLC (Triple-Level Cell) NAND flash memory, optimized for read-intensive workloads. Advanced wear-leveling algorithms distribute write operations evenly across all available memory cells, while background media management processes maintain optimal performance and extend the drive's operational lifespan.

Error Correction and Data Protection

Advanced ECC Capabilities

The drive incorporates sophisticated error correction code (ECC) mechanisms capable of correcting multiple bit errors per flash memory page. This robust error correction ensures data integrity even as the NAND flash memory ages and bit error rates naturally increase over time.

End-to-End Data Protection

Comprehensive end-to-end data protection mechanisms safeguard data throughout its journey within the drive. Protection covers data transfers between the host interface, drive controller, DRAM buffer, and NAND flash memory, ensuring data integrity at every stage of processing and storage.

Enterprise Security Features

Sanitize and Crypto Erase Functions

The drive supports instant sanitize commands that render all user data permanently inaccessible through cryptographic erasure. This functionality provides secure data disposal when repurposing or decommissioning drives, ensuring compliance with data privacy regulations and corporate security policies.

Power-Loss Protection Implementation

Advanced power-loss protection circuits ensure data integrity during unexpected power failures. The drive incorporates sufficient holdup capacitance to complete active write operations and commit all data from volatile buffers to non-volatile flash memory, preventing data loss or corruption during power interruption events.

HPE Gen10 Plus Server Optimization

Specifically engineered for HPE Gen10 Plus servers, this SSD delivers seamless integration with HPE's iLO (Integrated Lights-Out) management and HPE InfoSight for proactive monitoring and analytics. The drive's firmware includes HPE-specific optimizations that enhance performance, reliability, and management capabilities when deployed in compatible HPE server platforms.
