The Samsung PM1743 MZ3LO15THBLA-00A07 is a clear generational upgrade over the earlier MZ3LO15THBLA, moving to PCIe Gen5 x4 and delivering up to 14,000/7,100 MB/s and 2.5M/250K IOPS for substantially higher throughput in bandwidth-hungry, latency-sensitive enterprise platforms. With 15.36 TB capacity, 28,032 TBW endurance, and Samsung 6th-Gen 128-layer V-NAND TLC, it provides a stronger performance-per-slot and durability profile than its predecessor for virtualization clusters, high-speed analytics, and scale-out database tiers.
With an endurance rating of 28,032 TBW and 1 DWPD, the MZ3LO15THBLA-00A07 is designed to sustain consistent full-drive writes every day across its warranty period, making it well suited for steady enterprise workloads. In typical read-heavy or mixed-use deployment, this level of endurance provides a very comfortable margin and can support long-term use as a reliable system or application drive without concern over normal write wear. 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 rate of uncorrectable bit errors, supporting high data integrity, while the 2.5 million-hour MTBF further reflects a design built for dependable 24/7 operation.
1. The PCIe Gen5 x4 interface unlocks next-generation host bandwidth, helping enterprise servers clear data bottlenecks in AI training, real-time analytics, and high-density virtualization.
2. With up to 14,000 MB/s sequential read performance, the drive accelerates large dataset streaming, reducing application startup and model-loading time in data-intensive platforms.
3. Its 2,500,000 K random read IOPS, paired with 80 µs typical latency, enables ultra-fast access to small-block data, improving response consistency for OLTP databases, metadata services, and cache-heavy workloads.
4. A 1 DWPD endurance rating provides predictable day-after-day write capability, making it a strong fit for mixed enterprise workloads that require reliable lifespan without overprovisioning for unnecessary endurance.
5. Samsung V-NAND 6th-Gen 128-layer 3D TLC balances high density, power efficiency, and sustained performance, giving data centers a cost-effective flash foundation for scaling enterprise storage capacity.
Lower capacity reference: 7.68 TB Higher capacity reference: 30.72 TB At 15.36 TB, this SSD sits in the sweet spot of the family. Compared with 7.68 TB, it gives materially better headroom for dataset growth, longer refresh cycles, and fewer drive slots consumed in dense enterprise servers. Compared with 30.72 TB, it usually delivers a more attractive cost-per-deployment while maintaining essentially the same enterprise-class sequential and random performance profile, making budget planning easier. In practice, 15.36 TB is well suited for mid-scale virtualization clusters, such as supporting around 60 to 80 mixed-workload virtual desktops or application instances per storage tier.
Q: Is MZ3LO15THBLA-00A07 suitable for a write-heavy database server?
A: It can support mixed or moderate write database workloads, but for truly write-heavy servers, 1 DWPD may be limiting. We recommend validating daily write volume against the endurance target first.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 1 DWPD, meaning it can sustain one full 15.36 TB drive write per day during the warranty period, consistent with its 28,032 TBW endurance specification.
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, which is critical for enterprise systems requiring integrity, consistency, and reduced corruption risk.
Q: What RAID level is recommended for this SSD?
A: RAID choice depends on the workload. For performance and redundancy balance, RAID 10 is commonly recommended. For capacity efficiency with fault tolerance, RAID 5 or RAID 6 may also be considered.
