The PM1733 MZ-WLR3T8C is a clear generational step over the earlier MZ-WLR3T80, combining PCIe Gen4 x4 and Samsung 5th-Gen 92-layer V-NAND to deliver up to 7,000/3,800 MB/s and 1.45M/115K IOPS for substantially faster mixed enterprise workloads. At 3.84 TB with 1 DWPD and 7,008 TBW, it offers a stronger balance of throughput, endurance, and rack-level efficiency than prior-generation PCIe SSDs, making it especially compelling for virtualization clusters, high-speed analytics, and latency-sensitive database tiers.
With an endurance rating of 7008 TBW and 1 DWPD, the MZ-WLR3T8C is designed to handle a full drive write every day across its service life, which is more than sufficient for typical enterprise system-boot, virtualization, and mixed-read workloads. In practical terms, under normal OS and application usage, this level of endurance supports many years of stable operation and provides strong headroom for long-term deployment planning. For enterprise reliability, built-in Power Loss Protection (PLP) helps preserve in-flight data and mapping information during unexpected power interruptions, reducing the risk of corruption and unclean shutdown impact. Its UBER of 1.0E-17, combined with a 2 million hour MTBF, reflects very strong data integrity and dependable operation standards expected in data center environments.
1. The PCIe Gen4 x4 host interface provides the bandwidth needed to keep modern CPU and GPU servers fed, reducing storage bottlenecks in virtualization, analytics, and AI pipelines.
2. With 7000 MB/s sequential read performance, this drive accelerates large dataset ingestion, backup restore, and model loading so enterprise applications reach productive state faster.
3. Its 1,450,000 K random read IOPS capability supports extremely dense transaction and metadata-heavy workloads, helping databases and VM clusters sustain low-latency response under heavy concurrency.
4. A 1 DWPD endurance rating makes it well suited for mixed-use enterprise deployments that need predictable lifespan and lower replacement risk under steady daily write activity.
5. Samsung V-NAND 5th-Gen 92-layer 3D TLC combines enterprise-class density, power efficiency, and cost balance, enabling high-capacity flash tiers without sacrificing reliability for mainstream data center workloads.
Lower capacity reference: 1.92 TB Higher capacity reference: 7.68 TB At 3.84 TB, this model sits in the sweet spot of the series. Compared with the 1.92 TB version, it gives much more headroom for VM growth, log retention, and workload bursts without changing the familiar enterprise-class performance profile. Compared with the 7.68 TB option, it typically delivers a better balance of acquisition cost, usable capacity, and predictable latency, avoiding overprovisioning for many projects. It is especially well suited for mid-size virtualization, such as hosting OS and application volumes for about 40 to 60 mixed-workload virtual machines.
Q: Is MZ-WLR3T8C suitable for a write-heavy database server?
A: Yes, it is suitable for many write-intensive database workloads. With 1 DWPD, 7008 TBW, PCIe Gen4 x4, and 95 µs typical latency, it offers strong enterprise-grade write endurance and responsiveness.
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 3.84 TB drive write per day throughout its warranty term, aligned with its 7008 TB total endurance rating.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes power loss protection. PLP is critical because it helps preserve in-flight data and metadata during unexpected outages, reducing corruption risk and improving storage reliability in enterprise systems.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for database and virtualization environments requiring both performance and redundancy. For capacity-focused deployments, RAID 5 or RAID 6 may also be considered, depending on workload priorities.
