Technical Overview
The PM1743 achieves sequential read speeds up to 14,000 MB/s and write speeds up to 3,000 MB/s through its direct PCIe 5.0 x4 connection. Random 4KB performance reaches 2,000,000 IOPS for read operations and 150,000 IOPS for write operations, supporting demanding server applications.
With 3,504 TBW (Terabytes Written) endurance and a 1 DWPD (Drive Writes Per Day) rating, this SSD sustains heavy read workloads over extended deployment periods. The drive incorporates advanced error correction, end-to-end data protection, and power-loss protection to maintain data integrity during unexpected power events.
Relevant factors for this section include Storage Capacity, Maximum Read Transfer Rate, Maximum Write Transfer Rate, Random 4KB Read. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
Key Product Advantages
The ThinkSystem PM1743 combines cutting-edge NVMe technology with enterprise reliability features for server storage modernization. Samsung's V-NAND Machine Learning enables precise cell characteristic prediction and verification, while Fail-In-Place technology allows continued operation during NAND cell failures by identifying and relocating data without performance impact.
Virtualization Capabilities
Samsung's SSD virtualization technology subdivides a single drive into up to 64 independent virtual SSDs, creating isolated workspaces. This architecture supports Single-Root I/O Virtualization (SR-IOV), offloading tasks from server CPUs to reduce hardware requirements.
- Up to 64 virtual SSD partitions
- SR-IOV support
- Reduced server CPU utilization
Data Protection & Monitoring
Advanced ECC engine and end-to-end data protection safeguard against corruption. The drive includes Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) for proactive health monitoring and predictive failure analysis.

- End-to-end data protection
- S.M.A.R.T. monitoring
Deployment / Use Cases
The PM1743 is designed specifically for server environments where high read performance and data reliability are critical. Its read-intensive endurance profile makes it ideal for database servers, content delivery networks, virtual desktop infrastructure, and analytics platforms that process large datasets with frequent read access.
The 2.5" form factor with 15mm height fits standard server drive bays, while U.3 interface compatibility ensures broad server platform support. Backward compatibility with PCIe 4.0 and 3.0 allows deployment in existing server infrastructure while preparing for future PCIe 5.0 upgrades.
Database Server Storage
Delivers high random read performance for database query acceleration and transaction processing in SQL and NoSQL database environments.
Virtualization & Cloud Infrastructure
Supports virtual machine storage with consistent low latency for enterprise virtualization platforms and private cloud deployments.
Physical Profile
The 2.5" form factor measures 0.59" (15 mm) in height, 2.76" (70 mm) in width, and 3.94" (100 mm) in depth, with a weight of 6.70 oz (190 g). This compact design integrates into standard server drive bays without requiring specialized mounting hardware. The trayless design simplifies installation and maintenance in rack-mounted server configurations.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 0.59" (15 mm), 2.76" (70 mm), 3.94" (100 mm), 6.70 oz (190 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.
