Engineer's Note

Compared with the previous MZ-XLN1T60, the Samsung PM1735 MZXLR1T6HBJR-000H3 delivers a clear generational step forward with PCIe Gen4 x8 bandwidth, up to 7000 MB/s read throughput, and 1,000,000 random-read IOPS, making it notably stronger for latency-sensitive database, virtualization, and analytics workloads. Its 1.6TB capacity, 3 DWPD endurance, 8760 TBW rating, and Samsung V-NAND TLC also give it a better balance of sustained write durability and top-end performance than the earlier generation, especially in mixed-read/write enterprise deployments.

Endurance & Reliability

With an endurance rating of 8,760 TBW and 3 DWPD, this SSD is designed for sustained write-intensive enterprise workloads over its service life. In practical terms, under typical system, virtualization, or mixed application workloads, it provides ample write headroom for long-term deployment and can serve reliably as a primary system or data drive without endurance concerns in normal use. For enterprise reliability, the drive includes power loss protection (PLP), which helps preserve in-flight data and protect metadata integrity during unexpected power interruptions. Its UBER of 1.0E-17 and 2 million hour MTBF indicate a very low likelihood of uncorrectable bit errors and a high level of long-term operational dependability expected in data center environments.

Technical Specs & Insights

1. The PCIe Gen4 x8 interface provides enough host bandwidth to keep multi-core database, virtualization, and analytics servers fed without the bus becoming the performance bottleneck.
2. Its strong sequential read capability accelerates large file streaming, backup recovery, and AI model loading, reducing wait time for data-intensive enterprise workloads.
3. The very high random read performance enables fast response under heavy small-block access, which is critical for OLTP databases, virtual desktop infrastructure, and high-concurrency cloud services.
4. Built with Samsung V-NAND TLC and rated for intensive daily rewrites, it delivers the endurance and flash efficiency needed for mixed enterprise workloads without sacrificing capacity economics.
5. The low typical latency helps applications return data more predictably, improving QoS for latency-sensitive environments such as real-time analytics and transactional systems.

Capacity Sweet

Lower capacity reference: 800GB Higher capacity reference: 3.2TB The 1.6TB variant sits in the sweet spot of this enterprise SSD family. Compared with the 800GB model, it provides much better headroom for VM growth, database expansion, and overprovisioning flexibility, reducing the risk of early capacity pressure. Compared with the 3.2TB model, it keeps acquisition cost and replacement budget under tighter control while delivering essentially the same mainstream enterprise read/write and random IOPS profile. In practice, 1.6TB is a balanced choice for a mid-sized virtualization cluster, such as hosting boot and application volumes for about 40 to 60 virtual machines.
