Compared with predecessor MZWLO1T9HCJR, the MZ3LO1T9HCJR in the PM1743 Series advances to PCIe Gen 5.0 x4 and NVMe 2.0, delivering up to 13,000 MB/s sequential read and 2,500,000 random read IOPS for a clear generational uplift in host-side bandwidth and read concurrency. Its 1.92TB Samsung V6 128-layer 3D V-NAND TLC design, with 1 DWPD and 3504 TBW, makes it a strong fit for read-intensive enterprise workloads such as high-performance virtualization, analytics, and AI data-serving tiers that need Gen5-class responsiveness without moving to a higher-endurance drive.
With an endurance rating of 3504 TBW and 1 DWPD, the MZ3LO1T9HCJR-00B07 is designed to sustain writing its full capacity once per day throughout its rated service life, which is more than sufficient for typical enterprise boot, OS, application, and mixed-read workloads. In practical terms, under normal system-disk or read-intensive server usage, this level of endurance supports long-term deployment with strong wear margin and dependable lifecycle planning. For enterprise reliability, power loss protection (PLP) helps preserve in-flight data and metadata during unexpected power interruption, reducing the risk of corruption and improving system integrity. Its UBER of 1.0E-17, together with a 2.5 million-hour MTBF, indicates a very low probability of unrecoverable bit errors and a high expected operational reliability for business-critical environments.
1. The PCIe Gen 5.0 x4 interface with NVMe 2.0 unlocks a new tier of host-to-drive bandwidth and queue efficiency, helping dense servers remove storage bottlenecks in AI, analytics, and high-speed transactional workloads.
2. With sequential read performance of 13000 MB/s, this SSD accelerates large dataset streaming, reducing checkpoint restore, backup recovery, and data-lake scan times in enterprise environments.
3. Delivering 2,500,000 K IOPS in random reads, it sustains massive parallel access with minimal contention, which is especially valuable for virtualization clusters, metadata-heavy databases, and real-time inference platforms.
4. Rated at 1 DWPD, the drive is tuned for mixed enterprise workloads that need dependable write endurance over the full service life without overpaying for higher-than-needed durability.
5. Built on Samsung V6 (128-layer) 3D V-NAND TLC and paired with a typical latency of 80 µs, it combines mature flash efficiency with fast response times to keep latency-sensitive applications consistently responsive under load.
Lower-capacity reference: 960GB Higher-capacity reference: 3.84TB Capacity positioning analysis: In this series, the 1.92TB model sits at the sweet spot for mainstream enterprise deployment. Compared with the 960GB version, it gives much better headroom for OS images, application binaries, logs, and steady data growth, reducing early capacity pressure. Compared with the 3.84TB model, it typically delivers the best balance of acquisition cost, usable capacity, and performance consistency, since sequential throughput and random IOPS remain broadly similar across these capacities. It is especially well suited for mid-scale virtualization clusters, such as hosting boot and application volumes for about 40 to 60 business VMs.
Q: Is MZ3LO1T9HCJR-00B07 suitable for a write-heavy database server?
A: Yes, it can support database workloads, but its 1 DWPD rating makes it better for mixed-use or moderate write-heavy environments rather than extremely intensive, sustained write-heavy enterprise database servers.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This SSD is rated at 1 DWPD, meaning it can sustain one full 1.92TB drive write per day over the warranty period, aligned with its 3504TB total 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, which is critical for maintaining data integrity and system consistency.
Q: What RAID level is recommended for this SSD?
A: RAID 1, 10, or 5 can be considered depending on performance and redundancy needs. For databases and business-critical workloads, RAID 10 is typically the preferred balance of speed and protection.
