Samsung PM983 MZ1LB1T9HALS delivers a well-balanced 1.92 TB enterprise NVMe profile with PCIe 3.0 x4 performance up to 3,000/1,400 MB/s and 500K/46K IOPS, making it especially effective for read-centric virtualization clusters, boot-from-SAN pools, and scale-out cloud storage nodes that need strong random-read responsiveness without moving to a higher-cost mixed-use SSD class. Compared with the previous-generation MZ1LW1T9HMLS, this revision leverages Samsung V4 64-layer TLC NAND to provide a more modern media platform while sustaining enterprise durability at 1.3 DWPD / 2,733 TBW, giving architects a clearer upgrade path for better capacity efficiency and mainstream NVMe service performance.
With an endurance rating of 2733 TBW and 1.3 DWPD, the MZ1LB1T9HALS is designed to handle about 2.7 petabytes of total writes, which is more than sufficient for typical enterprise boot, system, and general-purpose server workloads over many years of operation. In practical terms, for common OS, logging, and application-drive usage, this level of endurance provides strong headroom and supports long-term deployment with confidence when operated within the specified workload profile. Its enterprise reliability is further strengthened by power-loss protection (PLP), which helps preserve in-flight data and protects metadata integrity during unexpected power interruptions, reducing the risk of corruption and unplanned recovery events. The specified UBER of 1.0E-17, together with a 2 million hour MTBF rating, indicates a very low probability of uncorrectable bit errors and a design target aligned with dependable data-center operation.
1. With a PCIe 3.0 x4 interface and NVMe 1.2 protocol, the drive delivers 3000 MB/s sequential read performance to speed up VM boot storms, backup recovery, and large-scale database scans.
2. Its 500,000 random-read IOPS capability helps dense virtualization, OLTP, and metadata-heavy applications maintain fast response times under high concurrency.
3. Rated at 1.3 DWPD, this SSD is built for mixed enterprise workloads that require consistent daily overwrites without sacrificing service life.
4. Samsung V4 64-layer TLC NAND balances enterprise-grade capacity, power efficiency, and cost, making it well suited for scale-out servers and mainstream data center deployments.
5. A typical latency of 85 µs reduces storage wait time for transactional applications, improving application responsiveness and QoS consistency in shared infrastructure.
Lower capacity: 960 GB Higher capacity: 3.84 TB The 1.92 TB MZ1LB1T9HALS sits at the sweet spot in its product family. Compared with the 960 GB model, it offers much better headroom for OS images, application data, logs, and growth, reducing the risk of early capacity pressure. Compared with the 3.84 TB version, it keeps acquisition cost and power budget more controlled while delivering essentially the same enterprise-class throughput and IOPS profile. This makes it a highly practical choice for mid-scale virtualization clusters, database nodes, or around 40 to 60 mixed-workload server boot and application volumes.
Q: Is MZ1LB1T9HALS suitable for a write-heavy database server?
A: Yes. With 1.3 DWPD, 2733 TBW endurance, TLC NAND, and 85 µs typical latency, MZ1LB1T9HALS is suitable for mixed and moderately write-heavy database workloads in enterprise environments.
Q: How many full drive writes per day can it actually endure over its warranty period?
A: This model is rated at 1.3 drive writes per day. For a 1.92 TB SSD, that equals about 2.5 TB of writes daily across its supported warranty 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 and database applications.
Q: What RAID level is recommended for this SSD?
A: RAID recommendation depends on workload. RAID 1 is common for OS or critical data, RAID 10 for high-performance databases, and RAID 5 or 6 for capacity-focused storage arrays.
