The Samsung PM1735 MZ-XLJ3T20 delivers standout value in the 3.2 TB enterprise tier by combining PCIe Gen4 x4 with TLC V-NAND to reach up to 7,000/3,800 MB/s and 1,000,000/250,000 IOPS, making it an excellent fit for latency-sensitive virtualization, high-throughput databases, and mixed read/write cloud workloads. Compared with the previous MZWLL3T2HAJQ-000H3 generation, it brings a clear interface and performance-class uplift while sustaining enterprise endurance at 3 DWPD and 17,520 TBW for more demanding 24/7 deployment profiles.
With an endurance rating of 17,520 TBW and 3 DWPD, the MZ-XLJ3T20 is built for sustained enterprise write workloads and can handle rewriting its full capacity three times per day throughout its rated service life. In typical server or system-disk use, this level of endurance is far beyond normal daily demand, giving procurement teams strong confidence in long-term deployment stability. For enterprise reliability, the drive includes power loss protection (PLP), which helps preserve in-flight data and prevents metadata corruption if power is interrupted unexpectedly. 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 dependable operation in business-critical environments.
1. The NVMe over PCIe Gen4 x4 design enables line-rate host connectivity that removes storage as a bottleneck for data-intensive workloads such as real-time analytics, checkpointing, and fast VM provisioning.
2. Its high sequential read capability accelerates large-block data movement, cutting application startup, database scan, and AI model load times in enterprise servers.
3. The strong random read performance supports dense virtualization and high-concurrency databases by sustaining fast access to small data blocks under heavy multi-tenant demand.
4. The enterprise endurance profile allows the drive to absorb sustained daily rewrites, making it well suited for write-active platforms such as OLTP, logging, caching, and hyperconverged infrastructure.
5. TLC V-NAND combined with low typical latency delivers a balanced mix of capacity efficiency, predictable QoS, and consistently responsive IO for latency-sensitive business applications.
Lower capacity reference: 1.6 TB (MZ-XLJ1T60) Higher capacity reference: 6.4 TB (MZ-XLJ6T40) At 3.2 TB, the MZ-XLJ3T20 sits at the sweet spot of the family. Compared with the 1.6 TB model, it gives much better headroom for OS images, application growth, log retention, and overprovisioning without changing the platform profile or expected enterprise-class throughput. Compared with the 6.4 TB version, it typically delivers the best balance between acquisition cost, usable capacity, and steady performance consistency. It is especially well suited for mid-scale virtualization clusters, such as hosting boot and application volumes for roughly 40 to 60 business workloads per node.
Q: Is MZ-XLJ3T20 suitable for a write-heavy database server?
A: Yes. With 3 DWPD, 17,520 TBW endurance, TLC V-NAND, PCIe Gen4 x4, and 95 microsecond typical latency, MZ-XLJ3T20 is well suited for write-intensive database and transactional workloads.
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. For a 3.2 TB SSD, that equals about 9.6 TB of writes daily, totaling 17,520 TBW over five years.
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, reducing corruption risk and improving reliability in databases, virtualization, and other enterprise environments.
Q: What RAID level is recommended for this SSD?
A: For most enterprise deployments, RAID 10 is the recommended choice. It provides strong performance, low write penalty, and fault tolerance, making it ideal for latency-sensitive and write-heavy applications.
