Compared with the previous-generation MZ-WLL1T6B, the PM1735 MZ-WLR1T60 advances into a much higher NVMe performance class with up to 7,000 MB/s sequential read throughput and 1,000,000 random-read IOPS, making it a stronger fit for latency-sensitive OLTP, real-time analytics, and dense virtualized infrastructure. Its 3 DWPD endurance, 8,760 TBW rating, and TLC V-NAND design give this 1.6TB model a compelling balance of sustained write durability and enterprise efficiency that outclasses typical mixed-use SSDs in the same capacity tier.
With an endurance rating of 8,760 TBW and 3 DWPD, the MZ-WLR1T60 is built for sustained enterprise write-intensive use, allowing the full drive capacity to be written three times per day throughout its rated service life. In typical deployment, this level of endurance is far beyond the needs of an OS or boot drive and is strong enough to support demanding server, cache, logging, or virtualization workloads with long-term confidence. For enterprise reliability, 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 rating of 1.0E-17, combined with a 2 million-hour MTBF, indicates a very low probability of unrecoverable bit errors and strong overall dependability for mission-critical environments.
1. The NVMe interface enables direct, low-overhead access to flash media, helping enterprise servers accelerate transactional workloads and reduce storage bottlenecks in virtualized environments.
2. This level of sequential read throughput shortens dataset loading, backup restore, and analytics scan times, making it well suited for AI pipelines and high-performance content delivery.
3. Its random read capability supports massive parallel access with consistently fast response under mixed workload pressure, which is critical for databases, metadata services, and large-scale VMs.
4. A 3 DWPD endurance rating gives enterprises the write tolerance needed for cache tiers, logging platforms, and intensive OLTP deployments without compromising service life.
5. TLC V-NAND combined with microsecond-class latency delivers a strong balance of density, efficiency, and predictable responsiveness for always-on cloud and mission-critical applications.
Lower capacity reference: 800GB Higher capacity reference: 3.2TB At 1.6TB, the MZ-WLR1T60 sits in the sweet spot of the series. Compared with the 800GB model, it offers much better headroom for OS images, application growth, logs, and overprovisioning, reducing the risk of early capacity pressure. Compared with the 3.2TB option, it keeps acquisition cost and fleet-wide budget under tighter control while delivering essentially the same enterprise-class sequential throughput and random IOPS. This makes 1.6TB especially well suited for mid-scale virtualization clusters, such as shared boot and utility storage for about 40 to 60 business application VMs.
Q: Is MZ-WLR1T60 suitable for a write-heavy database server?
A: Yes. The MZ-WLR1T60 is well suited for write-heavy database workloads, thanks to its 3 DWPD endurance, 8760 TBW rating, TLC V-NAND, low 100 µs latency, and NVMe interface.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 3 full drive writes per day. With 1.6TB capacity, that equals about 4.8TB of writes daily, aligning with its total endurance rating of 8760 TBW.
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 sudden power failure, reducing corruption risk and improving enterprise data integrity.
Q: What RAID level is recommended for this SSD?
A: The recommended RAID level depends on workload and availability goals. RAID 1 or RAID 10 is typically preferred for databases, balancing performance, redundancy, and fast recovery with enterprise NVMe SSDs.
