Compared with the previous-generation MZ-PLK3T20, the Samsung PM1735 MZ-PLJ3T20 advances to a PCIe Gen4 x8 architecture, delivering up to 8,000 MB/s sequential read and 1.5M random read IOPS to remove storage bottlenecks in data-intensive server platforms. Its 3.2 TB capacity, 3 DWPD endurance, 17,520 TBW rating, and Samsung V-NAND 3D TLC make it a stronger fit for mixed OLTP databases, virtualization clusters, and high-throughput analytics workloads that need both sustained write durability and top-tier read responsiveness.
With an endurance rating of 17,520 TBW, this SSD is built for sustained heavy use, equivalent to writing about 4.8 TB of data every day for 10 years. In practical terms, that is far beyond typical OS, application, and mixed enterprise workloads, making it a very safe choice for long-term deployment as a system or server boot drive. Its power loss protection (PLP) helps preserve in-flight data and metadata during unexpected power interruptions, reducing the risk of corruption and improving operational safety in enterprise environments. The UBER rating of 1.0E-17 means an extremely low unrecoverable bit error rate, supporting strong data integrity expectations for business-critical storage, while the 2 million hour MTBF further reflects enterprise-class reliability design.
1. The PCIe Gen4 x8 interface provides enough host bandwidth to keep modern dual-socket servers and storage nodes fully fed, reducing bottlenecks in data-intensive virtualization and analytics workloads.
2. With 8000 MB/s sequential read performance, the drive accelerates large dataset scans, backup restores, and AI model loading to shorten job start times across enterprise platforms.
3. Delivering 1,500,000 K IOPS in random reads, it is well suited for latency-sensitive OLTP databases, metadata-heavy cloud services, and high-concurrency VM environments.
4. Rated at 3 DWPD, the SSD can sustain heavy daily overwrite cycles for years, making it a strong fit for write-active enterprise applications such as logging, caching, and mixed-use databases.
5. Built on Samsung V-NAND 3D TLC and tuned for a typical latency of 100 µs, it balances high-density flash economics with the fast, predictable response time required in SLA-driven data center deployments.
Reference capacities in the same series: Lower capacity: 1.6 TB Higher capacity: 6.4 TB The 3.2 TB MZ-PLJ3T20 sits at the sweet spot of the lineup. Compared with the 1.6 TB model, it gives materially better headroom for OS images, application growth, logs, and overprovisioning, reducing early capacity pressure in mixed enterprise workloads. Compared with the 6.4 TB version, it delivers a more attractive balance of acquisition cost, usable capacity, and broadly similar enterprise performance characteristics. This makes it especially well suited for mid-scale virtualization clusters, such as hosting boot and application volumes for around 40 to 60 business VMs.
Q: Is MZ-PLJ3T20 suitable for a write-heavy database server?
A: Yes. With 3 DWPD, 17,520 TBW, Samsung V-NAND 3D TLC, and about 100 µs typical latency, the MZ-PLJ3T20 is well suited for write-intensive database and enterprise server workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: It is rated for 3 drive writes per day. For a 3.2 TB SSD, that equals about 9.6 TB of writes daily throughout the specified warranty period.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes PLP. This is critical because it helps protect in-flight data and metadata during sudden power failure, reducing corruption risk and improving enterprise storage reliability.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for this SSD in performance-sensitive and write-heavy environments, as it balances speed, redundancy, and rebuild reliability better than RAID 5 or RAID 6.
