Compared with the previous MZWLR7T6HALA-00007, the MZWLR7T6HALA-0007C moves to a PCIe Gen4 x4 architecture with Samsung 5th-Gen 92-layer V-NAND, delivering up to 7,000/3,800 MB/s and 1.45M/135K IOPS for clearly higher bandwidth and faster transaction handling in the same 7.68 TB class. With 14,016 TBW at 1 DWPD, the PM1733 is especially well suited to read-intensive virtualization, scale-out database, and analytics tiers that need next-generation performance with proven enterprise endurance.
With an endurance rating of 14,016 TBW and 1 DWPD, the MZWLR7T6HALA-0007C is designed to sustain full-drive writes every day throughout its rated service life, making it well suited for steady enterprise workloads. In practical terms, this level of endurance is far beyond typical OS boot or read-heavy application usage, so it can serve reliably as a system drive for many years under normal data center operating conditions. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve in-flight data and protects metadata integrity if power is suddenly interrupted. Its ultra-low UBER of 1.0E-17, combined with a 2 million hour MTBF, indicates a very high standard of data integrity and operational stability expected in business-critical storage environments.
1. The PCIe Gen4 x4 interface, paired with top-tier sequential read performance, accelerates large dataset streaming, VM boot storms, and analytics job startup in bandwidth-hungry servers.
2. Its exceptional random read capability sustains massive parallel access, making it ideal for high-concurrency OLTP databases, virtual desktop infrastructure, and read-intensive cloud platforms.
3. A 1 DWPD endurance rating provides predictable write resilience for everyday enterprise workloads, balancing durability and cost efficiency in mainstream data center deployments.
4. Samsung 5th-Gen 92-layer 3D TLC V-NAND delivers a strong mix of density, power efficiency, and reliability, helping enterprises scale capacity without sacrificing service consistency.
5. Typical latency of just 85 µs enables faster transaction response and tighter QoS control, which is critical for real-time applications and latency-sensitive shared storage environments.
Lower capacity reference: 3.84 TB Higher capacity reference: 15.36 TB In this SSD family, 7.68 TB sits at the sweet spot. Compared with the 3.84 TB model, it offers much better headroom for dataset growth, longer refresh cycles, and denser consolidation without changing the performance class. Compared with the 15.36 TB option, it usually delivers the most practical balance of acquisition cost, usable capacity, and predictable enterprise performance. This makes 7.68 TB especially well suited for mid-scale virtualization clusters, mixed OLTP and analytics nodes, or a 2U database server pool serving roughly 200 to 300 business application users.
Q: Is MZWLR7T6HALA-0007C suitable for a write-heavy database server?
A: Yes, it is suitable for mixed-use and moderately write-intensive database workloads. With 1 DWPD, 14,016 TBW, low 85 µs latency, and enterprise TLC NAND, it offers solid endurance and consistent performance.
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 7.68 TB drive write per day across its warranty period, aligned with its total endurance rating of 14,016 TBW.
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 outages, reducing corruption risk and maintaining storage integrity in enterprise servers and transactional applications.
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 speed. RAID 5 or 6 may suit capacity-focused environments with less write-intensive workloads.
