Product Overview

The Samsung PM1743 3.84TB E3.S PCIe 5.0 NVMe SSD represents Samsung's most advanced enterprise solid-state storage technology, engineered specifically for the demanding requirements of next-generation hyperscale data centres, AI/ML inference and training clusters, and high-performance enterprise computing environments. Built on the emerging E3.S form factor — a compact, thermally optimised standard designed for modern Open Compute Project (OCP) and EDSFF-compliant server architectures — the PM1743 harnesses the full bandwidth potential of the PCIe 5.0 interface to deliver sequential read performance that fundamentally redefines what enterprise NVMe storage can achieve.

As organisations worldwide accelerate their digital transformation journeys, the bottleneck has increasingly shifted from compute to storage. Traditional PCIe 4.0 NVMe drives, while capable, can no longer keep pace with the data ingestion, model training, and real-time analytics pipelines that define modern enterprise workloads. The Samsung PM1743 closes this gap decisively, doubling the available lane bandwidth compared to PCIe 4.0 platforms and enabling storage subsystems that can genuinely feed hungry GPU clusters, in-memory databases, and high-frequency transaction processing engines at the speed they require.

With 3.84TB of usable enterprise-grade NAND capacity, the PM1743 strikes an optimal balance between density, cost-efficiency, and endurance — making it an ideal choice for storage architects who need to maximise capacity per rack unit while maintaining the reliability and data integrity guarantees that mission-critical enterprise applications demand. Samsung's proven V-NAND technology and advanced controller firmware bring enterprise-class power loss protection, end-to-end data path protection, and sophisticated wear-levelling algorithms that extend the operational lifespan of the drive across the most write-intensive deployment scenarios.

Key Features & Benefits

• PCIe 5.0 x4 Interface: Delivers up to 2x the raw bandwidth of PCIe 4.0, enabling sequential read speeds exceeding 14,000 MB/s and dramatically reducing latency for AI/ML inference, database queries, and large-scale analytics pipelines.
• E3.S EDSFF Form Factor: The industry-standard E3.S (1T) form factor provides a thermally efficient, hot-plug-capable, and high-density alternative to traditional M.2 and U.2 drives, purpose-built for OCP server designs and next-generation rack architectures.
• Samsung V-NAND Technology: Samsung's proprietary Vertical NAND stacking technology delivers superior cell-to-cell isolation, higher endurance ratings, and improved data retention compared to conventional planar NAND, ensuring long-term reliability under continuous enterprise workloads.
• Enterprise Power Loss Protection (PLP): Integrated capacitor-backed power loss protection ensures that all in-flight data is safely committed to non-volatile storage during an unexpected power event, protecting data integrity and preventing file system corruption in mission-critical environments.
• End-to-End Data Path Protection: Advanced ECC and end-to-end data integrity features monitor and correct errors across the entire data path from host to NAND, guaranteeing bit-for-bit accuracy in environments where silent data corruption is unacceptable.
• NVMe 2.0 Protocol Compliance: Full compliance with the NVMe 2.0 specification ensures compatibility with the latest host software stacks, enables advanced queue depth management, and supports namespace management features critical for multi-tenant and virtualised storage environments.
• High Random IOPS: Delivers exceptional random 4K read IOPS performance suited for database transaction processing, virtual machine storage, and mixed-workload enterprise applications requiring consistent sub-millisecond response times.
• Optimised Thermal Design: The E3.S form factor's enhanced thermal envelope, combined with Samsung's intelligent drive-side thermal throttling firmware, ensures sustained peak performance even in high-density, thermally constrained server chassis without thermal-induced performance degradation.

Technical Architecture

At the heart of the Samsung PM1743 lies a custom Samsung enterprise NVMe controller paired with Samsung's latest generation V-NAND flash memory. The controller implements a highly parallelised internal architecture with multiple flash channels operating simultaneously, enabling the drive to sustain peak bandwidth figures even under sustained sequential workloads that would cause lesser drives to throttle. The PCIe 5.0 x4 host interface provides a theoretical maximum bandwidth of approximately 16 GB/s, and the PM1743's controller and NAND subsystem are architected to approach this ceiling under optimal sequential read conditions.

The E3.S 1T form factor itself is defined by the SNIA EDSFF (Enterprise and Data Centre SSD Form Factor) standard. Measuring approximately 112.75mm x 31.5mm, this form factor was co-developed by industry leaders including Samsung, Intel, and key OCP contributors to address the thermal and mechanical limitations of legacy U.2 and M.2 form factors when deployed at hyperscale. The connector interface is a standardised, hot-plug-capable edge connector that allows drives to be installed and removed without powering down the server, dramatically simplifying storage maintenance in production data centre environments.

Samsung's multi-layer V-NAND cells are stacked vertically using proprietary charge trap flash (CTF) technology, which eliminates the floating gate interference issues that limit the scalability of traditional planar NAND. This architectural choice translates directly into higher endurance drive ratings, better data retention under elevated temperatures, and more consistent write amplification characteristics across the drive's service life. Combined with the PM1743's advanced firmware-level wear-levelling and bad block management algorithms, this results in a drive that maintains performance and reliability consistency from first write to end of rated endurance.

Performance & Capacity

The Samsung PM1743 3.84TB variant is rated for sequential read performance of up to 14,000 MB/s and sequential write performance of up to 6,000 MB/s, figures that position it among the fastest enterprise NVMe SSDs commercially available. Random 4K read IOPS performance reaches approximately 2,500,000 IOPS, while random 4K write IOPS figures support the most demanding mixed-workload scenarios encountered in enterprise virtualisation platforms, relational database engines, and real-time analytics systems.

The 3.84TB capacity point represents a widely adopted enterprise sweet spot, providing sufficient raw storage for large in-memory database footprints, extensive virtual machine libraries, substantial AI model training datasets, or high-volume log and telemetry storage — all while remaining within the cost and power envelope that storage architects require when building out large-scale all-flash arrays or disaggregated storage nodes. Drive write endurance (TBW — Terabytes Written) is rated to enterprise-class standards, with the PM1743 designed to sustain continuous mixed read/write workloads across a multi-year operational lifecycle aligned with typical enterprise refresh cycles.

Power consumption under active workload conditions is optimised for the E3.S thermal envelope, with the drive designed to operate within the power budgets of OCP and standard EDSFF-compliant server platforms without requiring supplementary cooling infrastructure beyond what is provided by standard front-to-rear chassis airflow designs.
