Compared with the predecessor MZPLL1T6HCHP-00003, the PM1725a MZPLL1T6HEHP-000D3 advances to Samsung V3 48-layer TLC and a more mature PCIe 3.0 x8 NVMe 1.2 design, delivering up to 6,200/2,600 MB/s throughput and 1,000,000/180,000 IOPS while maintaining strong 5 DWPD endurance. This 1.6 TB drive is a particularly strong fit for latency-sensitive OLTP databases, virtualization clusters, and mixed read/write enterprise workloads that need both very high queue-depth performance and a long 14,600 TBW service life.
With an endurance rating of 14,600 TBW and 5 DWPD, the MZPLL1T6HEHP-000D3 is built for sustained write-intensive enterprise use, allowing the full drive capacity to be written about five times per day across its rated service life. In typical deployment, this level of endurance is far beyond the needs of a standard OS or boot drive, meaning it can operate for many years with ample margin under normal system workloads. For enterprise reliability, built-in power loss protection (PLP) helps preserve in-flight data and metadata during unexpected power interruption, reducing the risk of corruption and improving system integrity. Its ultra-low UBER of 1.0E-17, together with a 2 million hour MTBF, reflects very strong data integrity and long-term operational stability expected in data center environments.
1. The PCIe 3.0 x8 interface with NVMe 1.2 removes legacy storage bottlenecks and, with up to 6200 MB/s sequential read speed, accelerates data streaming, backup recovery, and large dataset loading in enterprise servers.
2. With 1,000,000 K random read IOPS, this SSD sustains extremely high transaction concurrency, making it ideal for latency-sensitive databases, virtualization clusters, and real-time analytics platforms.
3. A 5 DWPD endurance rating enables heavy daily overwrite workloads over the drive’s service life, giving enterprises the confidence to run write-intensive applications such as logging, caching, and OLTP without premature wear concerns.
4. Built on Samsung V3 (48L) TLC NAND, the drive balances strong capacity efficiency with enterprise-class performance consistency, helping data centers control cost without sacrificing reliability for mainstream mixed workloads.
5. A typical latency of 90 µs helps reduce storage response time at the microsecond level, improving application QoS and keeping CPUs better utilized in demanding cloud and mission-critical environments.
Lower capacity reference: 800 GB Higher capacity reference: 3.2 TB In this series, the 1.6 TB model sits in the sweet spot for mainstream enterprise deployment. Compared with the 800 GB version, it gives much better headroom for OS images, logs, hot data, and application growth, reducing early capacity pressure. Compared with the 3.2 TB option, it usually delivers a more attractive cost-per-drive while keeping broadly similar sequential throughput and random IOPS for typical enterprise workloads. It is especially well suited for mid-scale virtualization clusters, such as hosting boot and primary workload storage for around 40 to 60 mixed virtual machines.
Q: Is MZPLL1T6HEHP-000D3 suitable for a write-heavy database server?
A: Yes. With 5 DWPD, 14,600 TBW, low 90 µs latency, and enterprise NVMe design, MZPLL1T6HEHP-000D3 is well suited for write-intensive database, logging, and transactional server workloads.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated for 5 full drive writes per day. For a 1.6 TB SSD, that equals about 8 TB of writes daily within its specified endurance warranty conditions.
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 enterprise databases and critical write operations.
Q: What RAID level is recommended for this SSD?
A: For most server deployments, RAID 10 is commonly recommended because it balances performance, redundancy, and rebuild safety. RAID 1 is also suitable for smaller database or boot-oriented enterprise setups.
