Samsung PM1743 MZ3LO3T8HCJR-00AK0 is a strong upgrade from MZWLR30THBLA-00AD9, moving to PCIe Gen5 x4 and delivering up to 14,000/7,100 MB/s with 2.5M/250K IOPS—effectively doubling host-bandwidth headroom and significantly increasing read-intensive transaction throughput over the previous generation. For 3.84 TB enterprise deployments, its 6th-Gen Samsung V-NAND TLC, 1 DWPD endurance, and 7008 TBW make it a precise fit for high-density database, virtualization, and analytics nodes that need next-generation performance without sacrificing sustained reliability.
With an endurance rating of 7008 TBW and 1 DWPD, the MZ3LO3T8HCJR-00AK0 is designed to handle writing its full capacity once per day throughout its rated service life, which is more than sufficient for typical enterprise boot, read-intensive, and mainstream mixed-workload deployments. In practical terms, under normal system disk or server OS usage, this level of endurance provides long-term write headroom and helps ensure worry-free operation over many years. For enterprise reliability, the drive includes power loss protection (PLP), which helps preserve in-flight data and metadata during an unexpected power interruption, reducing the risk of corruption and improving system integrity. Its UBER rating of 1.0E-17, together with a 2.5 million hour MTBF, reflects a very low uncorrectable bit error rate and strong overall reliability expectations for data center environments.
1. The PCIe Gen5 x4 interface provides next-generation host bandwidth that removes storage bottlenecks in GPU servers, high-density virtualization clusters, and scale-out analytics platforms.
2. Its top-tier sequential read performance accelerates model staging, large database scans, and checkpoint recovery, helping enterprise systems return to productive work faster.
3. The extremely high random read throughput, paired with very low typical latency, sustains responsive service levels for metadata-heavy workloads such as OLTP databases, real-time inference, and high-concurrency cloud applications.
4. A 1 DWPD endurance rating aligns well with mainstream enterprise deployments, giving operators predictable write life for mixed-use workloads without overpaying for unnecessary durability headroom.
5. Samsung 6th-Gen V-NAND TLC combines enterprise-grade density, efficiency, and reliability, enabling strong performance per watt and lower total cost of ownership at fleet 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 gives much better headroom for dataset growth, VM density, and write buffering, 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 stronger balance of acquisition cost, usable capacity, and predictable latency, making it the most efficient mainstream choice. It is especially well suited for mid-scale virtualization clusters, mixed OLTP databases, or around 40 to 60 business application instances.
Q: Is MZ3LO3T8HCJR-00AK0 suitable for a write-heavy database server?
A: It can support mixed-use or moderate write-intensive database workloads, but with 1 DWPD, it is not ideal for extremely write-heavy environments. For sustained heavy writes, a higher-endurance SSD is recommended.
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 handle one full 3.84 TB drive write per day across its warranty period, consistent with its 7008 TBW endurance specification.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP is critical because it helps preserve in-flight data and metadata during sudden power failure, reducing corruption risk in enterprise and database systems.
Q: What RAID level is recommended for this SSD?
A: RAID 1 or RAID 10 is typically recommended for business-critical workloads, balancing redundancy and performance. RAID 5 may be used for capacity efficiency, but write penalty should be considered.
