Compared with the previous MPN MZWLR7T6HALA-00AD3, the Samsung PM1733 MZWLR7T6HALA-00007 delivers a clear generational uplift with PCIe Gen4 x4 performance, reaching 7,000/3,800 MB/s and up to 1.45M/135K random read/write IOPS for substantially faster response in latency-sensitive enterprise workloads. Its 7.68 TB capacity, 14,016 TBW endurance at 1 DWPD, and Samsung 5th-Gen 92-layer V-NAND 3D TLC make it a strong fit for virtualized databases, high-density compute nodes, and mixed read-heavy infrastructure that need higher throughput without sacrificing long-life write reliability.
With an endurance rating of 14,016 TBW, this SSD can sustain 14,016 terabytes of total host writes over its service life, which corresponds to about 3.8 TB of writes per day for 10 years or 1 full drive write per day in enterprise use. In practical terms, for typical OS, application, and mixed business workloads, this provides a very large endurance margin and makes it an extremely safe choice from a write-life perspective. Enterprise-grade reliability is further strengthened by power-loss protection (PLP), which helps preserve in-flight data and protects metadata integrity if power is suddenly interrupted. Its UBER rating of 1.0E-17 means an exceptionally low unrecoverable read error rate, giving buyers added confidence in data integrity for mission-critical and high-availability environments.
1. The PCIe Gen4 x4 interface, paired with top-tier sequential read bandwidth, accelerates dataset staging, VM boot storms, and large-scale analytics by cutting bulk transfer wait time across modern server platforms.
2. With up to 7000 MB/s sequential read performance, this drive shortens backup restore windows and speeds media, AI, and data lake workloads that stream massive files continuously.
3. Delivering 1,450,000 K IOPS in random reads, it sustains extremely high transaction concurrency for latency-sensitive databases, virtualization clusters, and high-QPS cloud services.
4. A 1 DWPD endurance rating makes it a strong fit for mixed-use enterprise deployments that need predictable lifespan under steady daily write pressure without overpaying for heavier write-class media.
5. Built on Samsung V-NAND 5th-Gen 92-layer 3D TLC and tuned for a typical 85 µs latency, it combines mature flash density with fast response consistency to improve application responsiveness in read-intensive infrastructure.
Reference capacities in the same series for the 7.68 TB MZWLR7T6HALA-00007 are: Lower capacity: 3.84 TB Higher capacity: 15.36 TB Typical enterprise-class performance across these three capacities is essentially similar: Sequential read: about 550 MB/s Sequential write: about 520 MB/s Random read: up to about 98K IOPS Random write: up to about 30K IOPS Capacity positioning analysis: At 7.68 TB, this SSD sits at the sweet spot of the family. Compared with the 3.84 TB version, it gives much more headroom for VM growth, database expansion, and longer retention without increasing drive count too quickly. Compared with the 15.36 TB version, it usually delivers the best balance between acquisition cost, usable capacity, and steady enterprise performance. It is well suited for mid-scale virtualization clusters, such as shared storage for about 40 to 60 mixed-workload virtual machines or a compact business-critical database tier.
Q: Is MZWLR7T6HALA-00007 suitable for a write-heavy database server?
A: It can support database workloads, but with 1 DWPD it is better suited to mixed-use or moderate write-intensive environments rather than extremely write-heavy servers with sustained high daily overwrite rates.
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 7.68 TB drive write per day across its warranty period, aligned with its 14,016 TBW endurance rating.
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, reducing corruption risk and improving reliability in enterprise and transactional storage environments.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is typically recommended for databases requiring both performance and redundancy. For capacity-focused deployments, RAID 5 or RAID 6 may be considered, depending on rebuild tolerance and write demands.
