Compared with the previous-generation MZWLL1T6HEHP, the PM1725b Series MZWLL1T6HAJQ-000D3 moves to Samsung 48-layer 3D V-NAND TLC and raises performance to up to 3,300/2,600 MB/s and 800,000/160,000 IOPS, delivering stronger mixed-workload throughput in the same 1.6TB PCIe Gen3 x4 NVMe class. With 5 DWPD and 14,600 TBW, it is a solid fit for write-intensive virtualization, OLTP databases, and caching tiers that need high endurance without sacrificing low-latency enterprise performance.
With an endurance rating of 14,600 TBW and 5 DWPD, the MZWLL1T6HAJQ-000D3 is built for sustained heavy-write enterprise workloads and can comfortably handle typical server or storage-system usage over many years. In practical terms, for common OS boot, logging, caching, and mixed application workloads, this level of endurance means the drive can be deployed with strong confidence and is far beyond the write demand of a typical system disk even over a long service life. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps protect in-flight data and metadata during unexpected power interruptions, reducing the risk of corruption and improving data integrity. Its UBER of 1.0E-17, together with a 2 million hour MTBF, indicates an enterprise-grade design focused on very low uncorrectable read error rates and dependable 24/7 operation in critical environments.
1. The PCIe Gen3 x4 NVMe architecture removes legacy SAS/SATA bottlenecks, enabling this drive to fully exploit modern server backplanes for faster data-path efficiency and better VM density.
2. With sequential read performance of up to 3300 MB/s, it accelerates large-block workloads such as database backup, analytics scans, and rapid dataset loading in enterprise platforms.
3. Its random read capability of 800,000 K IOPS supports highly concurrent applications, helping OLTP databases, virtualization clusters, and metadata-heavy systems sustain responsive performance under mixed demand.
4. Rated for 5 DWPD, it is built for write-intensive enterprise environments where logging, caching, and transaction-heavy workloads require consistent endurance over the full service life.
5. Samsung 48-layer 3D V-NAND TLC, paired with a typical latency of 90 µs, delivers a strong balance of flash density, cost efficiency, and low-response-time behavior for latency-sensitive business applications.
lower_capacity: 800GB higher_capacity: 3.2TB At 1.6TB, this SSD sits in the sweet spot of the series. Compared with the 800GB model, it gives meaningfully more headroom for OS images, application binaries, logs, and short-term data growth, reducing early capacity pressure and refresh risk. Compared with the 3.2TB version, it preserves nearly the same enterprise-class throughput and IOPS profile while delivering a more efficient cost-to-performance balance for mainstream deployments. It is especially well suited for mid-sized virtualization clusters, such as hosting boot and application volumes for around 40 to 60 business VMs.
Q: Is MZWLL1T6HAJQ-000D3 suitable for a write-heavy database server?
A: Yes. With 5 DWPD endurance, 14,600 TBW, low 90 µs typical latency, and enterprise NVMe performance, this 1.6TB SSD is well suited for write-intensive database and transactional server workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 5 DWPD, meaning it can sustain writing its full 1.6TB capacity five times per day throughout the defined warranty period under normal enterprise operating conditions.
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 preventing corruption and maintaining consistency in enterprise applications.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is generally recommended for this SSD in performance-sensitive enterprise environments, as it balances speed, redundancy, and write resilience better than RAID 5 for demanding database workloads.
