The Samsung PM983 1.88TB (MZ1LB1T9HBLS) is a strong upgrade from MZ1LW1T9HMLS, moving to 64-layer Samsung V4 TLC NAND and a PCIe 3.0 x4 NVMe 1.2 architecture to deliver up to 3000/1400 MB/s and 480K/42K IOPS for markedly better read responsiveness in dense server deployments. With 1.3 DWPD and 2733 TBW, it also provides a more balanced endurance-to-capacity profile than the prior generation, making it especially attractive for scale-out virtualization, read-heavy databases, and mixed enterprise boot/storage tiers where cost efficiency and predictable latency both matter.
With an endurance rating of 2,733 TBW and 1.3 DWPD, the MZ1LB1T9HBLS is designed to handle sustained daily write activity in typical enterprise and data-center workloads without concern about premature wear. In practical terms, this level of endurance is more than sufficient for long-term use as a system boot drive, virtualization node, or read/write mixed workload drive, supporting many years of stable operation under normal deployment conditions. For enterprise reliability, built-in Power Loss Protection helps preserve in-flight data and protect metadata integrity if power is interrupted unexpectedly, reducing the risk of corruption and unplanned recovery events. Its UBER of 1.0E-17, together with a 2 million hour MTBF, reflects strong data integrity and dependable operational stability, giving procurement teams confidence that the drive is suited for business-critical environments.
1. The PCIe 3.0 x4 interface with NVMe 1.2 provides a low-overhead, parallel data path that helps enterprise servers remove storage bottlenecks in virtualization, database, and scale-out application environments.
2. With 3000 MB/s sequential read performance, this SSD accelerates large-block workloads such as backup restore, analytics scans, and media streaming, reducing time to access bulk datasets.
3. Its 480,000 K IOPS random read capability is designed for transaction-heavy applications, enabling faster response in OLTP databases, VDI boot storms, and high-concurrency cloud services.
4. Rated at 1.3 DWPD, the drive offers write endurance suited to mixed-use enterprise deployments, supporting sustained daily rewrites with predictable lifecycle management in always-on systems.
5. Built with Samsung V4 (64L) TLC NAND and delivering a typical latency of 85 µs, it balances capacity efficiency with consistently quick access times for latency-sensitive business workloads.
Lower capacity reference: 960 GB Higher capacity reference: 3.84 TB The 1.88 TB model sits at the sweet spot of this SSD family. Compared with the 960 GB version, it provides much better headroom for OS images, logs, hot data, and capacity growth, reducing the risk of early overprovisioning pressure. Compared with the 3.84 TB version, it usually delivers the best balance between acquisition cost, usable capacity, and enterprise-class performance consistency. In practice, it is well suited for medium-scale virtualization, such as hosting boot and application volumes for roughly 40 to 60 business VMs in a 2U server.
Q: Is MZ1LB1T9HBLS suitable for a write-heavy database server?
A: Yes, it can support moderately write-intensive database workloads. With 1.3 DWPD, 2733 TBW, TLC NAND, and 85 µs latency, it is better suited for mixed enterprise workloads than extreme write-heavy environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: The rated endurance is 1.3 drive writes per day. For a 1.88 TB SSD, that equals about 2.44 TB of writes daily across its warranty term, within specification.
Q: Does it include power loss protection (PLP) and why is that critical?
A: Yes, this model includes power loss protection. PLP helps preserve in-flight data and metadata during sudden outages, which is critical for maintaining data integrity and reducing corruption risk in enterprise systems.
Q: What RAID level is recommended for this SSD?
A: RAID 10 is commonly recommended for enterprise SSD deployments requiring strong performance and redundancy. If capacity efficiency is more important, RAID 5 or RAID 6 may also be considered, depending on workload.
