The Samsung PM1735 (MPN: MZWLR1T6HBJR-00AD9) delivers a clear generational upgrade over MZWLL1T6HAJQ-00007 by moving to PCIe Gen4 x8 and 5th-Gen Samsung V-NAND TLC, enabling up to 7,000 MB/s read throughput and 1.4M random read IOPS for substantially faster response in latency-sensitive enterprise workloads. With 3 DWPD endurance and 8,760 TBW at 1.6 TB, it is especially well suited for mixed-read/write virtualization, high-frequency database logging, and cache-tier acceleration where sustained durability must match top-tier transactional performance.
With an endurance rating of 8,760 TBW and 3 DWPD, the MZWLR1T6HBJR-00AD9 is built for sustained heavy write workloads over its service life. In practical terms, for typical enterprise use—and especially for lighter-duty roles such as an OS or boot drive—this level of endurance provides ample write headroom for many years of reliable operation. This drive also includes power-loss protection (PLP), which helps preserve data in flight and protects mapping tables during unexpected power interruptions, reducing the risk of corruption or incomplete writes. Its enterprise-class UBER of 1.0E-17 means an extremely low probability of unrecoverable bit errors, giving buyers added confidence in data integrity and dependable long-term operation.
1. The PCIe Gen4 x8 interface provides the bandwidth headroom needed to keep multi-core servers and accelerator-rich platforms fed, reducing storage bottlenecks in data-intensive enterprise workloads.
2. Its high sequential read performance speeds up large-file access, helping databases, analytics clusters, and AI platforms load datasets and checkpoints faster.
3. The exceptional random read capability enables rapid access to massive volumes of small blocks, improving VM density, metadata responsiveness, and high-concurrency transaction processing.
4. With enterprise-grade write endurance, this SSD is well suited for write-intensive environments such as logging, caching, OLTP, and mixed-workload virtualization that demand consistent lifespan under daily heavy writes.
5. Samsung 5th-Gen V-NAND TLC combined with low typical latency delivers a strong balance of capacity efficiency, predictable QoS, and fast application response for latency-sensitive enterprise services.
Lower capacity reference: 800 GB Higher capacity reference: 3.2 TB In this enterprise SSD family, the 1.6 TB model sits at a practical sweet spot. Compared with the 800 GB version, it offers much better capacity headroom for mixed virtualized workloads, reducing early capacity pressure and leaving more room for growth. Compared with the 3.2 TB option, it preserves nearly the same enterprise-class sequential and random performance while delivering a more attractive cost-per-deployment balance. This makes 1.6 TB especially suitable for mid-scale clusters, such as hosting boot and application volumes for roughly 40 to 60 virtual machines.
Q: Is MZWLR1T6HBJR-00AD9 suitable for a write-heavy database server?
A: Yes. With 3 DWPD, 8,760 TBW endurance, PCIe Gen4 x8 bandwidth, and low 95 µs typical latency, this SSD is well suited for write-intensive database and enterprise transactional workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 3 DWPD, meaning the 1.6 TB capacity can be fully written about three times per day throughout the warranty period, consistent with its 8,760 TBW endurance rating.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP helps preserve in-flight data and metadata during unexpected outages, reducing corruption risk and improving reliability for databases, RAID arrays, and enterprise servers.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is typically recommended for performance-sensitive databases because it combines redundancy with strong write performance. For capacity-focused deployments, RAID 5 or RAID 6 may also be considered, depending on rebuild policy.
