Compared with MZWLR15THALA-00007, the MZWLR15THALA-0007C is the later PM1733 revision, combining PCIe Gen4 x4 with Samsung 5th-Gen 92-layer V-NAND to deliver up to 7,000/3,800 MB/s and 1.45M/135K IOPS in a 15.36 TB footprint. Its distinctive value is high-capacity, read-optimized enterprise performance with 28,032 TBW endurance, making it the stronger drop-in choice for dense virtualization clusters, scale-out storage, and analytics tiers that need more bandwidth and IOPS per drive than older PM1733 builds.
With an endurance rating of 28,032 TBW and 1 DWPD, this SSD is designed to support writing its full 15.36 TB capacity every day for five years, which is a strong fit for steady enterprise workloads. In typical real-world use such as OS, application, boot, cache, or mixed read-heavy server duties, this level of endurance provides a very large safety margin and can comfortably cover long service life expectations. For enterprise reliability, built-in Power Loss Protection (PLP) helps preserve in-flight data and protects mapping tables during unexpected power interruptions, reducing the risk of corruption and unplanned recovery events. Its UBER of 1.0E-17, together with a 2 million-hour MTBF, indicates enterprise-class data integrity and long-term operational stability, giving procurement teams confidence in dependable deployment.
1. The PCIe Gen4 x4 interface removes storage bottlenecks in modern servers, accelerating data-intensive workloads such as virtualization, analytics, and AI pipeline ingestion.
2. With sequential read performance of 7000 MB/s, this SSD enables much faster database warm-up, backup restore, and large dataset streaming across enterprise platforms.
3. Its random read capability of 1,450,000 K IOPS is built for highly concurrent environments, helping transactional databases and VDI clusters sustain responsive performance under heavy mixed-user demand.
4. Rated for 1 DWPD and built on Samsung V-NAND 5th-Gen 92-layer 3D TLC, it offers a balanced endurance profile for always-on enterprise deployments that need dependable write life without overprovisioning for extreme write workloads.
5. A typical latency of 85 µs helps reduce application wait time, improving QoS consistency for latency-sensitive services such as OLTP, real-time analytics, and scale-out cloud infrastructure.
Lower capacity reference: 7.68 TB Higher capacity reference: 30.72 TB At 15.36 TB, this SSD sits in the sweet spot of the family. Compared with the 7.68 TB option, it gives much better headroom for data growth, denser server configurations, and longer refresh cycles without changing the established enterprise performance profile. Compared with the 30.72 TB model, it delivers a more efficient balance of acquisition cost, usable capacity, and performance consistency, especially for mainstream mixed workloads. It is best suited for mid-scale virtualization clusters, such as hosting boot and application storage for roughly 40 to 60 general-purpose virtual machines.
Q: Is MZWLR15THALA-0007C suitable for a write-heavy database server?
A: It can support mixed-use or moderately write-intensive database workloads, but with 1 DWPD, it is not the best fit for extremely write-heavy environments compared with higher-endurance enterprise SSDs.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated at 1 DWPD, meaning it can sustain one full 15.36 TB drive write per day over its warranty period, aligned with the 28,032 TB TBW specification.
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 mapping tables during sudden outages, which is critical for enterprise reliability, consistency, and database integrity.
Q: What RAID level is recommended for this SSD?
A: For enterprise deployments, RAID 10 is typically recommended when performance and redundancy are priorities. If usable capacity matters more, RAID 5 or RAID 6 may also be considered.
