The Samsung PM1743 (MZ-WLO3T80) brings a clear generational step over MZ-7L34800 by moving to PCIe 5.0 x4 and delivering up to 14,000/5,700 MB/s sequential read/write with 2.4M/250K random read/write IOPS, giving modern servers far more bandwidth and read-side concurrency for AI data pipelines, high-frequency analytics, and dense virtualization clusters. At 3.84 TB, its 1 DWPD endurance rating and 7,008 TBW on Samsung 6th Gen V-NAND TLC make this MPN a strong fit for mixed enterprise workloads that need next-generation interface speed without sacrificing predictable durability and fleet-standard reliability.
With an endurance rating of 7008 TBW and 1 DWPD, the MZ-WLO3T80 is designed to support writing the equivalent of its full capacity once per day across its rated service life, which is more than sufficient for most server, boot, and mixed enterprise workloads. In practical terms, under typical system-disk or read-heavy application usage, this endurance level provides very comfortable long-term headroom and can support many years of stable operation without endurance becoming a concern. Its enterprise reliability profile is further strengthened by Power Loss Protection (PLP), which helps preserve in-flight data and metadata during unexpected power interruptions, reducing the risk of corruption or incomplete writes. The UBER specification of 1.0E-17 indicates an extremely low unrecoverable bit error rate, supporting strong data integrity expectations for business-critical environments, while the 2.5 million-hour MTBF reflects a design built for dependable continuous use.
1. The PCIe 5.0 x4 interface provides next-generation host bandwidth that prevents the SSD from becoming a bottleneck in GPU servers, real-time analytics platforms, and high-density virtualization clusters.
2. With 14,000 MB/s sequential read performance, this drive can dramatically shorten dataset staging, backup restore, and large-model load times in enterprise data pipelines.
3. Delivering 2,400,000K random read IOPS, it is built to sustain extremely high transaction concurrency for latency-sensitive databases, search engines, and cloud-scale read-heavy workloads.
4. Rated for 1 DWPD, the SSD offers enterprise-grade write endurance suitable for always-on mixed workloads where predictable lifespan and lower replacement risk matter more than burst-only performance.
5. Samsung 6th Gen V-NAND TLC combined with a typical latency of 75 µs enables fast, consistent response under sustained load, helping mission-critical applications maintain SLA stability and smoother QoS at scale.
Lower capacity reference: 1.92 TB Higher capacity reference: 7.68 TB In this series, the 3.84 TB model sits at the practical sweet spot. Compared with the 1.92 TB version, it provides much better headroom for dataset growth, mixed-workload consolidation, and longer refresh cycles without a major jump in operational complexity. Compared with the 7.68 TB option, it usually delivers the best balance of acquisition cost, usable capacity, and enterprise-class performance consistency, since sequential throughput and random IOPS are broadly similar across the family. It is especially well suited for mid-scale virtualization clusters, such as hosting boot and application volumes for around 40 to 60 business workloads.
Q: Is MZ-WLO3T80 suitable for a write-heavy database server?
A: MZ-WLO3T80 can support database workloads well, but for truly write-heavy environments, its 1 DWPD rating should be reviewed carefully. It is generally better suited for mixed-use enterprise applications.
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 sustain one full drive write per day over the warranty period. With 3.84 TB capacity, that equals about 3.84 TB daily.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, MZ-WLO3T80 includes power loss protection. PLP helps preserve in-flight data and metadata during unexpected outages, which is critical for preventing corruption and maintaining consistency in enterprise systems.
Q: What RAID level is recommended for this SSD?
A: For enterprise deployments, RAID 1, RAID 10, or RAID 5/6 may be considered depending on performance and redundancy needs. RAID 10 is commonly recommended for database and latency-sensitive workloads.
