Compared with the previous-generation MZ-XLN6T40, the PM1735 MZXL56T4HALA-00AH3 steps up to PCIe Gen4 x4 and delivers up to 7,000/3,800 MB/s with 1,450,000/250,000 IOPS, providing a clear generational gain in bandwidth and read performance for latency-sensitive enterprise workloads. Its 6.4TB Samsung V-NAND TLC design, combined with 3 DWPD and 35,040 TBW endurance, makes it a stronger choice than the prior model for write-intensive OLTP databases, dense virtualization clusters, and high-performance caching tiers that require sustained durability.
With an endurance rating of 35,040 TBW and 3 DWPD, the MZXL56T4HALA-00AH3 is built for sustained enterprise write-intensive workloads, allowing the full drive capacity to be written three times per day across its warranted service life. In practical terms, this level of endurance is far beyond typical OS, boot, and general server application demands, making it a dependable choice for long-term deployment with substantial write headroom. 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 UBER of 1.0E-17 indicates an extremely low uncorrectable bit error rate, while the 2 million hour MTBF further supports confidence in stable, continuous operation in data center environments.
1. The PCIe Gen4 x4 interface removes storage bottlenecks in modern dual-socket servers, enabling faster data ingestion and shorter job completion times for analytics, virtualization, and AI pipelines.
2. Its class-leading sequential read performance accelerates large-file access, cutting database warm-up, checkpoint restore, and model-loading time in data-intensive enterprise workloads.
3. The extremely high random read capability sustains responsive performance under heavily parallel access, making it ideal for OLTP databases, real-time search, and high-density virtual machines.
4. With enterprise-grade write endurance backed by Samsung V-NAND TLC, this drive is built for write-intensive environments such as logging, caching, and mixed-workload clusters without sacrificing flash efficiency.
5. The very low typical latency helps reduce tail-response delays, improving QoS consistency for latency-sensitive applications like trading platforms, metadata services, and inference serving.
Lower capacity reference: 3.2TB Higher capacity reference: 12.8TB The 6.4TB model sits at the sweet spot of the family. Compared with the 3.2TB version, it gives operators much better headroom for data growth, overprovisioning, and mixed-workload consolidation without changing the expected enterprise performance profile. Compared with the 12.8TB option, it delivers a more efficient balance of acquisition cost, usable capacity, and steady-state performance, avoiding unnecessary spend when extreme density is not required. It is best suited for mid-scale deployments, such as a virtualization cluster hosting about 40-60 business application virtual machines or a compact high-transaction database tier.
Q: Is MZXL56T4HALA-00AH3 suitable for a write-heavy database server?
A: Yes. With 3 DWPD endurance, 35,040 TBW, Samsung V-NAND TLC, and low 90 µs typical latency, this 6.4TB PCIe Gen4 x4 SSD is well suited for write-intensive database 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 6.4TB SSD, that equals about 19.2TB of writes daily across the warranty period, consistent with the 35,040TB TBW 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 enterprise databases, virtualization, and transactional applications.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is typically recommended for performance-critical enterprise workloads, balancing redundancy and speed. RAID 1 suits smaller deployments, while RAID 5 or 6 may be considered when capacity efficiency is prioritized.
