Compared with the previous-generation MZWLO3T8HBLS-00A07, the 3.84 TB Samsung PM1743 (MZWLO3T8HCLS-00B07) advances to PCIe Gen5 x4 and delivers up to 14,000/7,100 MB/s and 2,500,000/250,000 IOPS, giving it a clear generational advantage in host-side bandwidth and transaction density for latency-sensitive enterprise platforms. Its 1 DWPD rating, 7008 TBW endurance, and Samsung 6th-Gen 128-layer V-NAND TLC make it a strong fit for high-throughput database, virtualization, and analytics workloads that need next-generation performance without moving to a higher-endurance cost tier.
With an endurance rating of 7,008 TBW and 1 DWPD, the MZWLO3T8HCLS-00B07 is designed to sustain the equivalent of writing its full capacity once per day across the warranty period, which is more than sufficient for typical enterprise boot, OS, virtualization, and read-heavy application workloads. In practical terms, for common system-disk or mixed-use deployments, this level of endurance provides long service life and reliable daily operation with substantial write headroom. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve data in flight and protects metadata integrity during unexpected power interruptions, reducing the risk of corruption or incomplete writes. Its UBER of 1.0E-17 and MTBF of 2.5 million hours indicate a very low rate of unrecoverable bit errors and strong long-term operational reliability, making it a dependable choice for business-critical environments.
1. The PCIe Gen5 x4 interface paired with top-tier sequential read bandwidth enables ultra-fast dataset streaming and sharply reduces startup time for AI training nodes, in-memory databases, and analytics clusters.
2. Its random read capability is built for highly parallel enterprise workloads, sustaining massive transaction concurrency in virtualized platforms, metadata-heavy storage systems, and large-scale cloud services.
3. A 1 DWPD endurance profile gives enterprises the confidence to run continuous mixed workloads every day over the drive’s service life without overprovisioning for write wear.
4. Samsung 6th-Gen 128-layer 3D TLC V-NAND balances density, power efficiency, and reliability, making it well suited for performance-sensitive data center deployments that also require strong cost efficiency.
5. The 75 µs typical latency helps applications respond with near-instant data access, improving tail-latency behavior in real-time analytics, online transaction processing, and latency-sensitive scale-out infrastructure.
Lower capacity reference: 1.92 TB Higher capacity reference: 7.68 TB In this series, the 3.84 TB model sits in the sweet spot of the lineup. Compared with the 1.92 TB version, it gives much better headroom for OS images, application data, logs, and growth, reducing the risk of early capacity pressure while keeping the same enterprise-class performance profile. Compared with the 7.68 TB option, it delivers a more balanced acquisition cost and power footprint without overcommitting budget to unused space. It is well suited for mid-scale virtualization clusters, such as shared storage for about 40 to 60 general-purpose virtual machines.
Q: Is MZWLO3T8HCLS-00B07 suitable for a write-heavy database server?
A: Yes, it is suitable for moderately write-heavy database workloads. With 1 DWPD, 7008 TBW, low 75 µs latency, and PCIe Gen5 x4 performance, it fits enterprise database environments well.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 1 full drive write per day. For a 3.84 TB SSD, that means about 3.84 TB of writes daily within its specified warranty endurance limits.
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 in enterprise servers and storage systems.
Q: What RAID level is recommended for this SSD?
A: RAID 1, 10, or 5 can be selected depending on priorities. For databases, RAID 10 is typically recommended because it provides strong performance, redundancy, and faster rebuild behavior.
