Compared with MZ-WLK1T60, the Samsung PM1735 MZ-WLJ1T60 advances to PCIe Gen4 x4 and 5th-Gen V-NAND TLC, delivering up to 7,000 MB/s sequential read and 1,000,000 random read IOPS for materially higher per-drive bandwidth and OLTP virtualization density. Its 3 DWPD endurance and 8,760 TBW at 1.6 TB make it a strong fit for mixed read/write database, logging, and cache-tier deployments that need Gen4-class responsiveness without sacrificing enterprise write durability.
With an endurance rating of 8,760 TBW and 3 DWPD, the MZ-WLJ1T60 is designed for sustained write-intensive operation over its service life. In typical enterprise workloads, this level of endurance means it can comfortably serve as a system or cache drive for many years, with ample margin for daily writes and long-term stability. The drive also includes power loss protection (PLP), which helps preserve in-flight data and metadata during unexpected power interruptions, reducing the risk of corruption and improving operational safety. Combined with an UBER of 1.0E-17 and a 2 million-hour MTBF, it delivers enterprise-grade data integrity and reliability that procurement teams can deploy with confidence.
1. The PCIe Gen4 x4 interface, paired with top-tier sequential read bandwidth, accelerates large dataset streaming and VM/image loading, helping enterprise platforms reduce startup and recovery windows.
2. Its random read capability is built for highly concurrent OLTP databases, metadata-heavy virtualization, and cache-tier workloads where fast access to small blocks directly improves application responsiveness at scale.
3. A 3 DWPD endurance rating makes it a strong fit for write-intensive enterprise environments such as logging, analytics, and mixed transactional workloads that demand sustained reliability over the drive’s service life.
4. Samsung 5th-Gen V-NAND TLC balances density, performance, and cost efficiency, giving data centers enterprise-class flash economics without sacrificing consistency for mainstream and performance-sensitive deployments.
5. With a typical latency of 95 µs, the drive helps minimize storage-induced application delays, which is especially valuable for latency-sensitive databases, real-time services, and dense virtualized infrastructure.
Lower-capacity reference: 800 GB Higher-capacity reference: 3.2 TB Capacity positioning analysis: In this product family, 1.6 TB sits at a practical sweet spot between the 800 GB and 3.2 TB options. Compared with 800 GB, it gives noticeably more headroom for OS images, application growth, log retention, and overprovisioning without changing the expected enterprise-class read/write or random IOPS profile. Compared with 3.2 TB, it usually delivers a better cost-to-usable-capacity balance while keeping performance in the same operational tier. This makes 1.6 TB especially well suited for mid-scale virtualization clusters, such as shared storage for roughly 40 to 60 business application instances.
Q: Is MZ-WLJ1T60 suitable for a write-heavy database server?
A: Yes. With 3 DWPD endurance, 8,760 TBW, PCIe Gen4 x4 performance, 95 µs typical latency, and Samsung 5th-Gen TLC V-NAND, it 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: This model is rated for 3 drive writes per day. For a 1.6 TB capacity, that equals about 4.8 TB of writes daily across its specified warranty endurance period.
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 unexpected outages, reducing corruption risk and improving reliability for enterprise databases and transactional applications.
Q: What RAID level is recommended for this SSD?
A: For most enterprise deployments, RAID 10 is recommended to balance performance, redundancy, and low latency. If capacity efficiency matters more than write speed, RAID 5 or RAID 6 may also be considered.
