Compared with the previous-generation MZ-PLW3T20, the Samsung PM1735 (MZ-XLR3T20) advances to PCIe Gen4 x8 NVMe and delivers up to 8,000/3,800 MB/s with 1,500,000/250,000 IOPS, giving it a clear generational advantage in host bandwidth and transaction throughput for latency-sensitive enterprise platforms. Its 3 DWPD endurance and 17,520 TBW on Samsung V-NAND 3-bit MLC make this 3.2 TB drive a strong fit for write-intensive virtualization, OLTP databases, and high-frequency caching tiers that need both sustained durability and top-tier random read performance.
With an endurance rating of 17,520 TBW and 3 DWPD, the MZ-XLR3T20 is built to handle very heavy write-intensive workloads over its service life. In practical terms, under typical enterprise operating conditions, it can comfortably serve as a system or application drive for many years without endurance becoming a concern. The drive also includes enterprise-class reliability features such as Power Loss Protection (PLP), which helps preserve in-flight data and metadata if power is interrupted unexpectedly. Its UBER of 1.0E-17, together with a 2 million hour MTBF, indicates an extremely low probability of unrecoverable read errors and strong long-term operational reliability for business-critical deployments.
1. The PCIe Gen4 x8 NVMe architecture provides a wide host path and low software overhead, enabling this drive to keep modern database, virtualization, and analytics platforms fed without becoming a storage bottleneck.
2. Its class-leading sequential read performance accelerates large file streaming and dataset ingestion, cutting wait time for backup recovery, media processing, and AI model loading.
3. Exceptional random read capability paired with ultra-low typical latency sustains fast response under highly concurrent mixed workloads, which is critical for transactional databases and high-density virtual machines.
4. The enterprise endurance rating supports frequent full-drive rewrites over years of service, making it well suited for write-intensive logging, caching, and OLTP environments with predictable lifecycle planning.
5. Samsung V-NAND 3-bit MLC balances flash density, efficiency, and reliability, giving data centers strong cost-per-terabyte economics without sacrificing enterprise-class consistency.
Lower capacity reference: 1.6 TB Higher capacity reference: 6.4 TB In this enterprise SSD family, the 3.2 TB model sits at the sweet spot for mainstream deployment. Compared with the 1.6 TB version, it gives much better headroom for dataset growth, cache expansion, and overprovisioning without changing the expected enterprise-class read/write and random IOPS profile. Compared with the 6.4 TB option, it usually delivers the best balance between acquisition cost, usable capacity, and performance consistency. It is especially well suited for mid-scale virtualization clusters, such as hosting boot and application volumes for about 40 to 60 virtual machines.
Q: Is MZ-XLR3T20 suitable for a write-heavy database server?
A: Yes. The MZ-XLR3T20 is well suited for write-intensive database workloads, thanks to its 3 DWPD endurance, 17,520 TBW rating, low 90 µs latency, and enterprise NVMe Gen4 performance.
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 (DWPD), meaning the full 3.2 TB capacity can be overwritten three times daily throughout the official warranty period under normal conditions.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, it includes PLP. This is critical in enterprise environments because it helps protect in-flight data and metadata during unexpected power failure, reducing corruption risk and improving data integrity.
Q: What RAID level is recommended for this SSD?
A: RAID recommendation depends on your priority. RAID 1 or RAID 10 is typically preferred for databases and virtualization, while RAID 5 or RAID 6 may suit capacity-focused environments.
