The Samsung PM1735 6.4TB (MZPLJ6T4HALA-00AD3) stands out for high-throughput enterprise workloads by combining PCIe Gen4 x4, Samsung 5th-Gen TLC V-NAND, and sustained 3 DWPD endurance, delivering up to 8,000/3,800 MB/s and 1,500,000/250,000 IOPS with a massive 35,040 TBW rating. Compared with the previous-generation MZPLK6T4HMLA-00005, this model brings a clear platform step-up to Gen4 bandwidth and newer V-NAND, giving it materially higher sequential and random performance while preserving data-center-class write endurance for latency-sensitive OLTP, virtualization, and mixed read/write analytics clusters.
With an endurance rating of 35,040 TBW and 3 DWPD, the MZPLJ6T4HALA-00AD3 is built for sustained write-intensive enterprise workloads, allowing the full drive capacity to be written three times per day throughout its rated service life. In practical terms, this level of endurance is far beyond typical OS boot or general server application usage, making it a very safe choice for long-term deployment under normal data center operating conditions. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve in-flight data and protects metadata integrity if system power is suddenly interrupted. Its UBER specification of 1.0E-17 indicates an extremely low probability of unrecoverable bit errors during reads, supporting dependable data integrity for business-critical storage environments.
1. The PCIe Gen4 x4 interface, paired with very high sequential bandwidth, accelerates large dataset streaming, VM image loading, and backup recovery in performance-critical servers.
2. Its exceptional random-read capability sustains dense OLTP, real-time analytics, and metadata-heavy cloud workloads without becoming a storage bottleneck.
3. The 3 DWPD endurance rating makes it a strong fit for write-intensive enterprise environments such as logging, caching, and mixed database workloads that demand predictable lifespan.
4. Samsung 5th-Gen V-NAND TLC balances enterprise-class capacity, power efficiency, and cost, making it well suited for scale-out infrastructure with demanding duty cycles.
5. The low typical latency helps reduce tail-response times, improving QoS consistency for latency-sensitive applications like high-frequency transactions and virtualized storage clusters.
Lower capacity reference: 3.84 TB Higher capacity reference: 7.68 TB Capacity positioning analysis: At 6.4 TB, this model sits at a practical sweet spot in the family. Compared with the 3.84 TB option, it gives materially better headroom for data growth, overprovisioning, and mixed enterprise workloads without changing the expected class of sequential throughput or random IOPS. Compared with 7.68 TB, it usually delivers a more attractive cost-per-deployment while keeping performance in the same enterprise range. This makes 6.4 TB especially well suited for mid-scale virtualization clusters, database nodes, or hyperconverged storage pools serving roughly 40 to 60 business applications.
Q: Is MZPLJ6T4HALA-00AD3 suitable for a write-heavy database server?
A: Yes. With 3 DWPD endurance, 35,040 TBW, PCIe Gen4 x4 performance, and Samsung 5th-Gen TLC V-NAND, this 6.4 TB SSD is well suited for write-intensive database and enterprise workloads.
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. For a 6.4 TB capacity, that equals about 19.2 TB of writes daily, consistent with its 35,040 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 sudden outages, reducing corruption risk and supporting data integrity in transactional or mission-critical systems.
Q: What RAID level is recommended for this SSD?
A: RAID recommendation depends on your goal. RAID 1 or RAID 10 is preferred for databases needing strong redundancy and performance, while RAID 5 or RAID 6 suits capacity-focused environments.
