The Samsung PM1743 15.36TB (MPN: MZWLO15THBLA-00B07) is a strong fit for latency-sensitive database, virtualization, and analytics tiers, combining PCIe Gen5 x4 bandwidth with 13,000/6,600 MB/s sequential performance, 2.5M random-read IOPS, and enterprise-class endurance of 1 DWPD / 28,032 TBW on 6th Gen V-NAND TLC. Compared with the previous-generation MZWLJ15THALA, this model delivers a clear platform upgrade to Gen5 with materially higher throughput and read parallelism, making it the better choice for consolidating high-density mixed workloads without sacrificing endurance.
With an endurance rating of 28,032 TBW and 1 DWPD, this SSD is designed to handle sustained enterprise write workloads while still maintaining a very large lifetime write budget. In typical real-world use such as an OS boot drive, virtualization host boot storage, or other read-dominant server workloads, this level of endurance is generally more than sufficient for 10 years of worry-free operation. Its power-loss protection (PLP) helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and improving operational continuity. The ultra-low UBER of 1.0E-17, together with a 2.5 million-hour MTBF, indicates enterprise-class data integrity and long-term reliability, giving procurement teams confidence for business-critical deployments.
1. The NVMe PCIe Gen5 x4 interface, paired with up to 13,000 MB/s sequential read bandwidth, enables ultra-fast dataset streaming and significantly shortens checkpoint, cache-warmup, and large-file access times in AI and analytics clusters.
2. With random read performance reaching 2,500,000 K IOPS, this drive can sustain extremely heavy metadata, indexing, and small-block query workloads without becoming a bottleneck in high-concurrency databases.
3. A 1 DWPD endurance rating makes it well suited for mixed enterprise workloads that require predictable daily write capacity over the service life without overprovisioning for unnecessary endurance.
4. Samsung V-NAND 6th Gen TLC provides a strong balance of density, efficiency, and cost, helping data centers scale flash capacity economically while maintaining enterprise-class performance consistency.
5. The typical 80 µs latency supports faster application response and tighter QoS control, which is critical for latency-sensitive virtualization, transaction processing, and real-time inferencing environments.
lower_capacity: 7.68TB higher_capacity: 30.72TB At 15.36TB, this SSD sits in the sweet spot of the product family. Compared with the 7.68TB model, it gives meaningfully more headroom for dataset growth, longer refresh cycles, and better consolidation efficiency without changing the expected enterprise-class performance profile. Compared with the 30.72TB option, it delivers a more attractive balance of acquisition cost, usable capacity, and operational efficiency while keeping similar sequential and random I/O behavior. It is especially well suited for mid-scale virtualization clusters, mixed database nodes, or high-density read-intensive application pools.
Q: Is MZWLO15THBLA-00B07 suitable for a write-heavy database server?
A: It can support database workloads, but with 1 DWPD it is better suited for mixed-use or moderate write-intensive environments rather than extremely write-heavy servers with sustained high daily overwrite rates.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated at 1 DWPD, meaning it can handle one full 15.36TB drive write per day across its warranty period, aligned with its 28,032TB 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 power failure, reducing corruption risk and improving data integrity in enterprise environments.
Q: What RAID level is recommended for this SSD?
A: RAID choice depends on workload goals. RAID 1 or RAID 10 is commonly recommended for strong redundancy and performance, while RAID 5 or 6 may suit capacity-focused deployments.
