The Samsung PM1733 MZ-WLR3T80 delivers standout value in the 3.84 TB class by combining PCIe Gen4 x4 bandwidth, Samsung 5th-Gen 9x-Layer 3D TLC V-NAND, and up to 7,000/3,800 MB/s with 1,450,000/115,000 IOPS, making it a strong fit for latency-sensitive virtualization, scale-out databases, and mixed read/write enterprise workloads. Compared with the previous MZWLR3T8HBLS generation, it represents a clear platform uplift with next-generation Gen4 performance while sustaining enterprise endurance at 1 DWPD and 7,008 TBW, enabling higher workload density per drive without sacrificing reliability.
With an endurance rating of 7,008 TBW and 1 DWPD, the MZ-WLR3T80 is built to handle a full drive write per day across its warranty life, which is more than sufficient for typical enterprise boot, system, and mixed-read application workloads. In practical terms, this level of endurance means buyers can confidently deploy it as a reliable system or infrastructure drive for many years of normal operation without concern about write wear becoming a near-term limitation. For enterprise reliability, the drive includes power loss protection (PLP), which helps safeguard in-flight data and mapping metadata during an unexpected power interruption, reducing the risk of corruption and unplanned recovery events. Its UBER of 1.0E-17 and 2 million-hour MTBF indicate a very low probability of uncorrectable bit errors and strong long-term operational stability, providing the level of data integrity and dependability expected in business-critical environments.
1. The PCIe Gen4 x4 host interface provides enough parallel bandwidth to keep modern servers from being storage-bound, improving throughput for AI pipelines, virtualization clusters, and real-time analytics.
2. Its strong sequential read performance shortens the time needed to load large datasets, restore backups, and stream massive files into compute nodes.
3. The very high random read capability enables fast response under heavily concurrent small-block access, making it well suited for OLTP databases, VDI, and metadata-intensive cloud workloads.
4. With a write endurance profile aligned to full-drive rewrites in enterprise duty cycles and Samsung’s advanced 3D TLC V-NAND, it balances long service life, stable write behavior, and cost-efficient capacity for always-on deployments.
5. The low typical latency helps applications reach data with minimal wait time, improving tail-response consistency for latency-sensitive services such as caching, trading, and interactive analytics.
Lower capacity reference: 1.92 TB Higher capacity reference: 7.68 TB At 3.84 TB, the MZ-WLR3T80 sits at the sweet spot of the series. Compared with the 1.92 TB model, it provides much better headroom for OS images, application growth, logs, and mixed virtualized workloads, reducing early capacity pressure. Compared with the 7.68 TB option, it delivers a more attractive balance of acquisition cost, usable flash, and enterprise-grade performance, since sequential throughput and random IOPS remain broadly similar across capacities. This makes it especially well suited for mid-scale virtualization clusters, database replicas, and dense boot-storage pools for roughly 40 to 60 servers.
Q: Is MZ-WLR3T80 suitable for a write-heavy database server?
A: Yes, it can support database workloads well. With 1 DWPD, 7008 TBW, PCIe Gen4 x4, and 95 µs typical latency, it fits mixed to moderately write-heavy enterprise database environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: The rated endurance is 1 DWPD, meaning the 3.84 TB drive can be fully written once per day throughout its warranty period, consistent with its 7008 TBW specification.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, the MZ-WLR3T80 includes power loss protection. PLP helps preserve in-flight data and metadata during sudden outages, which is critical for data integrity, database consistency, and enterprise reliability.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for enterprise SSD deployments requiring strong performance and redundancy. If capacity efficiency is more important, RAID 5 or RAID 6 may also be considered.
