The Samsung PM1735 MZ-PLJ6T40 stands out for high-throughput, write-intensive enterprise workloads by combining 6.4 TB of 5th-Gen V-NAND TLC with PCIe Gen4 x8 performance up to 8,000/3,800 MB/s and 1.5M/250K IOPS, while sustaining 3 DWPD and 35,040 TBW for long-life deployment. Compared with the previous-generation MZPLK6T4HMLA-00005, it moves to PCIe Gen4 x8 and delivers roughly 29% higher sequential read, 46% higher sequential write, 50% higher random read, and 39% higher random write performance, making it a stronger fit for latency-sensitive databases, virtualization, and mixed-read/write cloud storage nodes.
With an endurance rating of 35,040 TBW and 3 DWPD, the MZ-PLJ6T40 is built for sustained write-intensive enterprise workloads over its service life. In practical terms, this level of endurance means it can comfortably handle typical server and system-disk usage for many years, including frequent logging, database activity, virtualization, and cache workloads, without endurance becoming a concern. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve in-flight data and protect metadata integrity if power is suddenly interrupted. Its UBER of 1.0E-17 indicates an extremely low probability of unrecoverable bit errors during reads, supporting dependable data integrity in business-critical environments, while the 2 million hour MTBF further reflects strong overall reliability.
1. The PCIe Gen4 x8 host interface, paired with class-leading sequential throughput, keeps analytics clusters, backup nodes, and media pipelines fed fast enough to remove storage as a bottleneck.
2. Its exceptional random-read capability enables dense virtualization, large-scale databases, and AI feature-serving workloads to retrieve massive volumes of small data with consistently high responsiveness.
3. The 3 DWPD endurance rating makes it a strong fit for write-intensive enterprise environments such as OLTP systems, log-heavy platforms, and mixed-use cloud infrastructure that demand predictable lifespan under sustained daily churn.
4. Samsung 5th-Gen V-NAND TLC balances enterprise capacity efficiency with dependable performance retention, helping data centers scale flash deployment without sacrificing reliability or cost discipline.
5. With typical latency in the sub–hundred-microsecond class, the drive helps transaction engines and latency-sensitive applications respond faster, improving SLA stability during peak load.
Lower capacity reference: 3.2 TB Higher capacity reference: 12.8 TB Within this series, the 6.4 TB model is the sweet-spot capacity. Compared with the 3.2 TB option, it gives much better headroom for data growth, overprovisioning, and workload bursts without changing the expected enterprise-class read/write and IOPS profile. Compared with the 12.8 TB model, it usually delivers the best balance of usable capacity, acquisition cost, and deployment efficiency, avoiding overbuying for mid-scale projects. It is especially well suited for a virtualization cluster hosting around 40 to 60 mixed-application virtual machines or a compact high-transaction database tier.
Q: Is MZ-PLJ6T40 suitable for a write-heavy database server?
A: Yes. The MZ-PLJ6T40 is well suited for write-heavy database workloads, thanks to its 3 DWPD endurance, 35,040 TBW rating, low 95 µs latency, and enterprise-grade Samsung V-NAND TLC.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 3 full drive writes per day. With 6.4 TB capacity, that equals about 19.2 TB of writes daily, aligning with its enterprise endurance specification and TBW rating.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP is critical because it helps preserve in-flight data and metadata during unexpected outages, reducing corruption risk and improving reliability in enterprise environments.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for this SSD in performance-sensitive environments, as it balances speed, redundancy, and rebuild efficiency. For capacity-focused deployments, RAID 5 or RAID 6 may also be considered.
