Engineer's Note

Compared with the previous-generation MZWLL3T2HAJQ-000H3, the PM1735 MZXLJ3T2HBLS-000H8 moves to NVMe PCIe Gen4 x4, effectively doubling host-interface bandwidth and delivering up to 7,000/3,800 MB/s with 1,000,000/250,000 IOPS for a clear step-up in throughput and latency consistency. Its 3.2 TB TLC V-NAND design also combines 3 DWPD and 17,520 TBW endurance, making it a stronger fit than its predecessor for write-intensive virtualization clusters, high-frequency OLTP databases, and mixed enterprise workloads that need both speed and sustained durability.

Endurance & Reliability

With an endurance rating of 17,520 TBW and 3 DWPD, this SSD is built to sustain intensive write workloads over its service life, making it well suited for enterprise servers, virtualization, databases, and high-traffic storage environments. In practical terms, under typical OS, application, and mixed enterprise workloads, this level of endurance provides long-term peace of mind and can comfortably support use as a system or data drive for many years without endurance becoming a concern. For enterprise reliability, the drive includes power loss protection (PLP), which helps preserve in-flight data and protects metadata integrity if power is interrupted unexpectedly. Its ultra-low UBER of 1.0E-17, together with a 2 million hour MTBF, indicates a very low probability of uncorrectable read errors and supports dependable operation in business-critical deployments.

Technical Specs & Insights

1. The NVMe over PCIe Gen4 x4 architecture provides the bandwidth and parallelism needed to keep virtualized databases, analytics nodes, and scale-out application servers from being bottlenecked by storage.
2. Its 7000 MB/s sequential read capability accelerates large-block workloads such as AI model loading, backup restore, media processing, and data lake scans.
3. With 1,000,000 K random read IOPS, the drive can sustain extremely dense transaction and metadata-heavy workloads, improving responsiveness in cloud platforms and high-concurrency OLTP environments.
4. A 3 DWPD endurance rating makes it well suited for write-intensive enterprise use cases, allowing predictable lifespan under continuous logging, caching, and mixed database activity.
5. TLC V-NAND paired with a typical latency of 95 µs delivers a strong balance of cost efficiency, flash density, and fast response time for latency-sensitive business applications.

Capacity Sweet

Reference capacities in the same family: Lower capacity: 1.6 TB Higher capacity: 6.4 TB At 3.2 TB, this SSD sits in the sweet spot of the lineup. Compared with the 1.6 TB model, it gives much better headroom for OS images, active datasets, logs, and growth, reducing the risk of early capacity pressure. Compared with the 6.4 TB version, it usually delivers a more attractive cost profile while keeping broadly similar enterprise-class sequential and random performance. That makes 3.2 TB a balanced choice for mid-scale virtualization clusters, database nodes, or roughly 40 to 60 mixed-workload application servers.
