Compared with the previous-generation MZWLW3T2HMLA, the MZWLR3T2HBLS-00AD3 moves to a PCIe Gen 4.0 x8 NVMe architecture and Samsung V6 128-layer 3D V-NAND TLC, delivering up to 7,000/3,800 MB/s and 1.4M/235K IOPS for substantially higher bandwidth and queue-depth scalability. With 3 DWPD and 17,520 TBW in a 3.2TB footprint, this PM1735 Series drive is the stronger choice for write-intensive OLTP databases, dense virtualization clusters, and real-time analytics nodes that need both sustained endurance and low-latency performance.
With an endurance rating of 17,520 TBW and 3 DWPD, the MZWLR3T2HBLS-00AD3 is designed for sustained write-intensive enterprise workloads and can handle full-drive writes every day throughout its service life. In typical server or system-disk usage, this level of endurance provides a very large safety margin, making it a dependable choice for long-term deployment without concern over normal write wear. For enterprise reliability, the drive includes Power Loss Protection (PLP), which helps preserve in-flight data and protects mapping tables if unexpected power failure occurs. Its UBER rating of 1.0E-17, together with a 2 million hour MTBF, indicates extremely strong data integrity and dependable operational stability for business-critical environments.
1. The PCIe Gen4 NVMe interface provides enough host-side bandwidth to keep modern database, virtualization, and GPU servers fully utilized instead of bottlenecked by storage.
2. Its strong sequential read capability shortens dataset loading, backup recovery, and analytics scan times, helping large jobs start and finish faster.
3. Exceptional random-read performance supports high VM density and responsive service levels in heavily concurrent OLTP, VDI, and metadata-intensive environments.
4. Enterprise-class write endurance allows the drive to handle sustained logging, caching, and write-heavy database workloads with lower replacement risk over its service life.
5. Samsung’s high-layer TLC V-NAND, combined with very low typical latency, delivers predictable QoS and fast application response for latency-sensitive cloud and transactional workloads.
Lower capacity reference: 1.6TB Higher capacity reference: 6.4TB The 3.2TB model sits at the sweet spot of this enterprise SSD family. Compared with the 1.6TB option, it gives meaningfully better capacity headroom for OS images, hot data, and growth buffers, reducing early overprovisioning pressure in shared infrastructure. Compared with the 6.4TB version, it delivers a more balanced acquisition cost while keeping essentially the same enterprise-class sequential throughput and random IOPS profile. This makes 3.2TB especially well suited for mid-scale virtualization clusters, such as hosting system and application volumes for about 60 to 80 mixed-workload virtual machines.
Q: Is MZWLR3T2HBLS-00AD3 suitable for a write-heavy database server?
A: Yes. With 3 DWPD endurance, 17,520 TBW, TLC V-NAND, and low 90 µs typical latency, this 3.2TB PCIe Gen4 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 about three full 3.2TB writes per day throughout its warranty period, consistent with its 17,520 TBW endurance specification.
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 for databases, virtualization, and enterprise storage systems.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is typically recommended for this SSD in performance-sensitive enterprise environments, as it balances speed, redundancy, and rebuild reliability better than RAID 5 or RAID 6 for write-heavy workloads.
