Compared with the previous MZWLW15THGLA, the MZWLR15THALA-00007 in the PM1733 Series advances to PCIe Gen4 x4 NVMe and delivers up to 7,000 MB/s sequential read and 1.45M random read IOPS, providing a clear generational gain in host-side bandwidth and read-intensive transaction throughput. With 15.36TB capacity, Samsung V5 3D TLC V-NAND, and 28,032 TBW at 1 DWPD, it is a strong fit for dense virtualized infrastructure, scale-out analytics, and mixed enterprise workloads that need high capacity without sacrificing consistent performance.
With an endurance rating of 28,032 TBW and 1 DWPD, this SSD is built to handle writing its full capacity every day across its rated service life, which is far beyond the needs of typical OS, application, and mainstream server workloads. In practical terms, under normal enterprise system-disk or mixed read/write usage, it provides long-term write endurance that supports stable operation for many years without endurance-related concern. For enterprise reliability, built-in power loss protection (PLP) helps preserve in-flight data and protects metadata integrity during unexpected power interruptions, reducing the risk of corruption and unplanned recovery events. Its 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 further reflects strong design reliability for continuous operation.
1. The PCIe Gen4 x4 NVMe architecture gives this drive the bandwidth needed to keep GPUs, analytics pipelines, and virtualized workloads fed without storage becoming the bottleneck.
2. Its top-tier sequential read performance sharply reduces large dataset loading, backup restore, and media streaming times in data center environments.
3. The very high random read capability is ideal for read-intensive databases, metadata-heavy file systems, and large-scale virtualization where fast access to small blocks drives application responsiveness.
4. A 1 DWPD endurance profile makes it well suited for mainstream enterprise deployments that need dependable full-drive daily rewrites over the service life without overpaying for extreme write endurance.
5. Samsung V5 3D V-NAND TLC paired with low typical latency delivers a strong balance of density, power efficiency, and consistently fast response for latency-sensitive cloud and enterprise applications.
Lower capacity reference: 7.68TB Higher capacity reference: 30.72TB At 15.36TB, this SSD sits in the sweet spot of the family. Compared with the 7.68TB version, it gives materially more headroom for dataset growth, longer refresh cycles, and better consolidation efficiency 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 fleet-wide budget control, while avoiding overprovisioning. In practice, it is well suited for mid-scale virtualization clusters, mixed OLTP databases, or a 2U node serving roughly 150 to 250 general-purpose VDI users.
Q: Is MZWLR15THALA-00007 suitable for a write-heavy database server?
A: Yes, it can support database workloads well. With 1 DWPD, 28,032 TBW, PCIe 4.0 NVMe, and low 100 µs latency, it fits mixed to moderately write-heavy enterprise environments.
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 sustain one full 15.36 TB drive write per day throughout its warranty period, consistent with the 28,032 TBW endurance rating.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes PLP. This is critical because it helps protect in-flight data and metadata during sudden power loss, reducing corruption risk and improving reliability in enterprise servers.
Q: What RAID level is recommended for this SSD?
A: For most enterprise deployments, RAID 10 is recommended for the best balance of performance, redundancy, and rebuild safety. RAID 5 or 6 may suit capacity-focused, read-dominant workloads.
