Compared with MZWLR1T6HCJR-00007, the PM1735 Series MZWLR1T6HCJR-00AD3 moves to a PCIe Gen4 x4 NVMe platform with Samsung 128-layer V-NAND TLC, delivering up to 7,000 MB/s sequential read, 1,000,000 random-read IOPS, and 8,760 TBW in a 1.6TB, 3-DWPD profile. This makes it a stronger fit than the previous generation for latency-sensitive virtualization, high-transaction databases, and mixed-read enterprise workloads that need higher front-end bandwidth without sacrificing endurance.
With an endurance rating of 8,760 TBW and 3 DWPD, the MZWLR1T6HCJR-00AD3 is built for sustained heavy-write enterprise workloads and can support writing its full capacity three times every day throughout its rated service life. In typical server use, this level of endurance means the drive can operate as a highly dependable system, boot, or application disk for many years with substantial margin, giving buyers confidence in long-term deployment stability. For enterprise reliability, the drive includes power loss protection (PLP), which helps preserve in-flight data and protects metadata integrity if power is unexpectedly interrupted. Its ultra-low UBER of 1.0E-17, together with a 2 million hour MTBF, indicates a very low probability of uncorrectable read errors and supports the high data integrity and operational reliability expected in business-critical environments.
1. The PCIe Gen4 NVMe architecture enables near-local-memory data delivery, accelerating AI model loading, VM startup, and large-scale dataset ingestion in modern servers.
2. Its top-tier sequential throughput shortens backup windows, speeds media processing, and keeps data pipelines fed in bandwidth-hungry analytics environments.
3. The exceptional random-read performance keeps databases, virtual desktops, and search platforms highly responsive when thousands of small requests hit simultaneously.
4. This high-endurance profile is built for write-heavy enterprise workloads such as caching, logging, and transactional systems that demand long service life under constant updates.
5. Samsung’s advanced high-layer TLC V-NAND combines strong density, power efficiency, and predictable latency, making it a practical fit for dense cloud infrastructure and mainstream enterprise storage tiers.
Lower capacity reference: 800GB Higher capacity reference: 3.2TB In this series, the 1.6TB model sits at the sweet spot for mainstream enterprise deployment. Compared with the 800GB version, it offers much better headroom for OS images, logs, hot datasets, and future growth, reducing early capacity pressure without changing the expected enterprise-class read/write and random IOPS profile too much. Compared with the 3.2TB option, it delivers a more attractive cost-per-node balance while keeping performance in the same practical tier. It is well suited for medium-scale virtualization, such as shared boot and application storage for around 40 to 60 business service instances.
Q: Is MZWLR1T6HCJR-00AD3 suitable for a write-heavy database server?
A: Yes. With 3 DWPD endurance, 8760 TBW, low 90 µs typical latency, and Samsung 128-layer TLC V-NAND, this 1.6TB NVMe SSD is well suited for write-intensive database workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 3 DWPD, meaning the drive can handle writing its full 1.6TB capacity three times per day throughout the warranty period, within the specified endurance limits.
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, which is critical for maintaining data integrity and reducing corruption risk.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for this SSD in performance-critical environments, as it balances high read/write performance, redundancy, and faster rebuilds better than parity-based RAID levels.
