Compared with the previous-generation MZ-PLK12T0, the PM1733 MZXL515HALA-00AH3 advances to NVMe PCIe Gen4 x8 and increases capacity to 15.36TB, delivering up to 8,000/3,800 MB/s and 1,500,000/250,000 IOPS for noticeably higher bandwidth, I/O density, and rack-level consolidation. With Samsung V-NAND 3-bit MLC rated at 1 DWPD and 28,032 TBW, it is a strong choice for read-intensive analytics, scale-out databases, and virtualized infrastructure that need a clear generational performance uplift without giving up enterprise-class endurance.
With an endurance rating of 28,032 TBW and 1 DWPD, the MZXL515HALA-00AH3 is built to handle a full drive write every day across its rated service life, making it well suited for steady enterprise workloads. In typical real-world use, this level of endurance means it can serve reliably for many years as a boot drive or mixed-use data drive without endurance becoming a practical concern. Its enterprise-grade reliability is further strengthened by power loss protection (PLP), which helps preserve in-flight data and metadata during unexpected power interruptions, reducing the risk of corruption or incomplete writes. An UBER of 1.0E-17 indicates an extremely low uncorrectable bit error rate, supporting high data integrity for business-critical environments, while the 2 million hour MTBF provides additional confidence in long-term operational stability.
1. The NVMe over PCIe Gen4 x8 architecture provides the bandwidth headroom and parallelism needed to keep GPU servers, high-core-count databases, and scale-out storage nodes fed without interface bottlenecks.
2. Its sequential read performance accelerates large-block data movement, cutting wait times for analytics scans, checkpoint restores, and massive media or backup ingestion jobs.
3. The very high random read capability enables dense virtualization, OLTP, and metadata-heavy workloads to serve far more concurrent requests with consistently faster application response.
4. A 1 DWPD endurance profile makes it well suited for read-centric enterprise deployments that still require dependable daily full-drive rewrites over the service life of the SSD.
5. Samsung V-NAND 3-bit MLC, paired with typical latency of just 95 µs, delivers an efficient balance of capacity, power efficiency, and predictable low-latency behavior for cloud and enterprise storage platforms.
Lower reference capacity: 7.68TB Higher reference capacity: 30.72TB Within this SSD family, 15.36TB is the sweet-spot capacity. Compared with the 7.68TB model, it gives meaningfully better space headroom for VM growth, hot data retention, and denser node consolidation without changing the expected enterprise-class read/write or random IOPS profile. Compared with the 30.72TB model, it usually delivers the best balance of usable capacity, acquisition cost, and risk concentration per drive. It is especially well suited for mid-scale virtualization clusters, high-density database nodes, or all-flash storage pools serving roughly 150 to 250 mixed enterprise workloads.
Q: Is MZXL515HALA-00AH3 suitable for a write-heavy database server?
A: It can support mixed database workloads, but with 1 DWPD, it is better suited to read-intensive or balanced environments. For consistently write-heavy databases, a higher-endurance SSD would be 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 15.36TB drive write per day. Based on 28,032 TBW, that corresponds to approximately five years of use.
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 critical metadata during unexpected outages, reducing corruption risk and improving reliability in enterprise and database applications.
Q: What RAID level is recommended for this SSD?
A: For enterprise database or virtualization workloads, RAID 10 is usually the preferred choice, as it provides strong performance, low latency, and redundancy. RAID selection should still follow capacity and fault-tolerance requirements.
