Performance Characteristics and Benchmarks

Sustained Read/Write Performance

With sequential read speeds up to 560MB/s and write speeds up to 510MB/s, the 400-AZUU delivers consistent performance under varying workloads. Random performance reaches up to 97,000 IOPS for reads and 36,000 IOPS for writes, making it suitable for mixed application environments.

Latency and Quality of Service

Average latency remains below 150 microseconds for reads and below 20 microseconds for writes, ensuring responsive application performance. The drive maintains consistent Quality of Service (QoS) with 99.9% of I/O operations completing within predictable latency thresholds.

Mixed Use Classification: Balanced Read/Write Endurance

Understanding DWPD and TBW Ratings

Drive Writes Per Day (DWPD) Specification

Rated at 1.3 DWPD, the 400-AZUU can withstand having its entire 1.92TB capacity written 1.3 times per day throughout its 5-year warranty period. This translates to approximately 2.5TB of data written daily, significantly higher than read-intensive drives rated at 0.5-1 DWPD.

Total Bytes Written (TBW) Endurance

With a TBW rating of 4.2 petabytes, this SSD can endure extensive write operations over its lifespan. This endurance level makes it suitable for applications with moderate write requirements, including database operations, virtualization, and collaborative environments.

Workload Optimization Strategies

Adaptive Caching and Write Acceleration

The controller implements sophisticated write caching algorithms that optimize performance for mixed workloads. A portion of the TLC NAND operates in pseudo-SLC mode during write-intensive operations, temporarily boosting write performance before background processes move data to TLC storage.

Garbage Collection and TRIM Support

Advanced background garbage collection maintains optimal performance by proactively erasing unused memory blocks. TRIM command support ensures the operating system can inform the SSD about unused data blocks, improving both performance and endurance over time.

Enterprise Reliability and Data Protection

Power Loss Protection Mechanisms

Capacitor-Based Power Loss Protection

Integrated power loss protection circuits include capacitors that provide sufficient temporary power to complete in-progress writes and flush cache contents to non-volatile storage during unexpected power interruptions. This prevents data corruption and maintains data integrity.

End-to-End Data Protection

The implementation of end-to-end data protection ensures data integrity from the host interface through the DRAM cache to the NAND flash. Each data transfer includes CRC verification, while the NAND flash incorporates advanced ECC capabilities to correct multiple bit errors per page.

Advanced Error Correction and Monitoring

LDPC Error Correction Code

Low-Density Parity Check (LDPC) error correction provides robust protection against data corruption, capable of correcting multiple bit errors within each memory page. This technology becomes increasingly important as NAND flash cells shrink and become more susceptible to read disturbs and retention errors.

SMART Monitoring and Predictive Analytics

Comprehensive SMART (Self-Monitoring, Analysis, and Reporting Technology) attributes monitor drive health, including wear level, bad block count, temperature history, and error rates. Dell's proprietary management tools leverage this data for predictive failure analysis and proactive maintenance scheduling.
