With its E3.s form factor, it is optimized for high-density storage deployments and scalable infrastructure environments.

Advanced PCIe 5.0 Technology for High-Bandwidth Applications

One of the standout features of the Samsung PM1743 3.84TB SSD is its use of the PCIe 5.0 interface, offering double the data bandwidth compared to PCIe 4.0. With a theoretical throughput of up to 32 GT/s per lane, PCIe 5.0 x4 allows this SSD to reach maximum speeds of 13,000 MB/s for read operations, making it ideal for compute-intensive environments such as AI/ML workloads, real-time analytics, and high-frequency trading platforms.

How PCIe 5.0 Improves Enterprise Storage

• Reduces bottlenecks for I/O intensive applications
• Enhances virtualization and container performance
• Improves scalability and latency responsiveness
• Enables faster boot times and load sequences

E3.s Form Factor for Scalable Data Center Deployments

The E3.s form factor is part of the EDSFF (Enterprise and Data Center SSD Form Factor) family, designed specifically for high-density, next-generation storage environments. Unlike the U.2 and M.2 form factors, the E3.s layout enables better airflow, thermal performance, and physical scalability. The 2.5-inch sizing also ensures compatibility with newer server chassis designed for EDSFF devices, contributing to improved system design flexibility and maintenance.

Benefits of E3.s Over Traditional 2.5-Inch Drives

• Improved thermal management
• Higher density per rack unit
• Enhanced connector durability
• Standardized interoperability in modern servers

Enterprise-Grade Reliability and Endurance

Designed for mission-critical environments, the Samsung PM1743 series emphasizes reliability and endurance. With a 1 DWPD endurance rating and a mean time between failures (MTBF) of 2.5 million hours, the MZ-3LO3T80 model supports sustained heavy workloads typical in database servers, content delivery networks (CDNs), and large-scale VDI deployments.

Power Loss Protection and Data Integrity

Samsung integrates advanced power loss protection capacitors and end-to-end data path protection in the PM1743 series. These features ensure that in the event of sudden power failure, all in-flight data is safely written to the NAND flash, minimizing data loss and enhancing system stability. This makes the drive suitable for compliance-heavy environments like financial institutions and healthcare systems.

SMART Reporting and Monitoring Tools

The SSD comes with comprehensive support for SMART commands, providing real-time data on drive health, usage statistics, and error rates. Administrators can use Samsung's proprietary management software or third-party monitoring tools to ensure optimal operation and lifecycle tracking.

NVMe 2.0 Protocol Enhancements

With full support for the NVMe 2.0 protocol, the Samsung PM1743 leverages enhancements like Zoned Namespaces (ZNS), Namespace Management, and Persistent Memory Regions (PMR). These advanced features streamline operations, reduce latency, and allow greater control over how data is stored and retrieved, particularly in multi-tenant and software-defined storage environments.

Namespace Flexibility for Virtualized Systems

Namespace support allows segmentation of the physical SSD into isolated logical drives, improving workload separation and reducing contention. This is particularly useful in containerized environments and hyper-converged infrastructure, where consistent QoS and resource predictability are essential.

Performance Optimization for Modern Workloads

Whether supporting artificial intelligence workloads, high-resolution video editing, or transactional database systems, the Samsung PM1743 MZ-3LO3T80 excels across the board. Its high throughput, coupled with minimal latency, ensures top-tier performance across a wide range of enterprise scenarios.

Application Use Cases

• Big data analytics and real-time data processing
• Virtual Desktop Infrastructure (VDI) and cloud computing
• IoT data ingestion and time-sensitive sensor analytics
• Media streaming and 4K/8K content delivery networks
• Scientific computing and research simulations

Latency Reduction Mechanisms

Low queue depth optimizations and firmware-level tuning help reduce latency, enabling consistent performance even during mixed read/write workloads. Samsung’s proprietary controller and firmware architecture minimize command overhead, ensuring responsiveness remains steady under peak loads.

Security and Compliance

Security features embedded in the PM1743 include hardware-based encryption, secure boot, and support for TCG Opal and IEEE 1667 standards. These mechanisms help ensure that sensitive data is protected from unauthorized access while simplifying compliance with regulatory mandates such as HIPAA, GDPR, and PCI-DSS.

Encryption and Secure Erase

The drive includes AES 256-bit encryption and fast secure erase capabilities, enabling organizations to protect data in rest and quickly decommission drives when needed. This is especially valuable in environments with stringent data disposal policies.

Compatibility and Integration

The MZ-3LO3T80 SSD is validated for use with leading enterprise server platforms and supports a broad ecosystem of operating systems, hypervisors, and management tools. Compatibility with Linux, Windows Server, VMware ESXi, and various cloud-native platforms ensures that it can be seamlessly integrated into existing infrastructures.

Plug-and-Play Support in EDSFF-Compatible Racks

Thanks to its E3.s design and PCIe 5.0 interface, the drive can be easily hot-swapped in compatible systems, reducing downtime during maintenance and allowing scalable upgrades as performance requirements evolve.

Thermal Efficiency and Power Management

Advanced power management features and superior thermal design make the PM1743 SSD energy-efficient. Dynamic Thermal Guard monitors temperature levels and adjusts performance to prevent overheating, extending drive lifespan and reducing system cooling requirements.

Low TDP for Green Data Centers

With a lower Thermal Design Power (TDP) compared to previous generations, the drive supports green IT initiatives by reducing power consumption without compromising performance. This makes it a strong candidate for sustainability-conscious enterprises.

Samsung’s Legacy of NAND Innovation

Samsung is a global leader in NAND flash memory, and the PM1743 series benefits from cutting-edge V-NAND technology. The 6th-generation V-NAND used in this SSD provides faster I/O performance, lower power usage, and improved endurance, ensuring long-term value and reliability in mission-critical deployments.

Firmware Optimization and Updates

Samsung provides robust firmware update tools and lifecycle support, allowing IT departments to maintain optimal device performance with minimal manual intervention. Firmware upgrades can be executed with zero downtime in certain environments, ensuring business continuity.
