SSD Drive Samsung Server PM1743, 3.84TB, 2.5", PCIe 5.0 x4 NVMe BULK - MZWLO3T8HCLS-00A07

Samsung PM1743 3.84TB is an enterprise PCIe NVMe SSD, aimed at serious server and storage workloads, where speed and reliability are more important than anything else. It operates via a PCIe 5.0 x4 interface with the NVMe 2.0 protocol and reaches up to 14000MB/s sequential reading – levels that are beyond the capabilities of standard consumer SSD drives. The form factor is 2.5" U.2 (SFF-8639), so it is aimed at server platforms and professional storage systems, not typical desktop cases. The capacity of 3.84TB provides serious room for databases, virtual machines, high-IOPS applications, and heavy backend services.

What you get

With this drive, you get enterprise-level performance and durability: up to 2 500 000 IOPS at 4KB random read and 280 000 IOPS at 4KB random write mean that arrays of small requests – databases, virtualization, microservices – are served with minimal latency. A TBW of 7008TB and a design life of 5 years are a clear indication that the drive is created for writing all day, every day, in server environments. Samsung V-NAND 3-bit MLC (TLC) memory is balanced between capacity and durability, while End-to-End Data Protection, Power Loss Protection (PLP), and hardware AES-XTS 256-bit encryption protect your data during errors, power drops, and security requirements. Thanks to dual-port PCIe support, you can build high-availability configurations with two controllers connected to the same drive for fault-tolerant environments.

• Capacity 3.84TB – sufficient for large databases, dozens of virtual machines, or as a fast tier in hybrid storage arrays.
• Reading speed up to 14000MB/s – massive acceleration during sequential access, suitable for heavy read workloads, backups, and analytical tasks.
• Up to 2 500 000 IOPS (4KB random read) and up to 280 000 IOPS (4KB random write) – optimized for intensive random operations such as OLTP databases and virtualization.
• PCIe NVMe 5.0, support for Gen4/Gen5 x4 – flexibility to use it in both newer and older server platforms without losing compatibility.
• 2.5" U.2 form factor (SFF-8639) – compatible with modern server chassis and storage backplanes, optimized for easy replacement (hot-swap).
• Dual-port PCIe (single-port x4 or dual-port x2/x2) – allows connection to two separate controllers for high availability and fault tolerance.
• Hardware AES-XTS 256-bit encryption and TCG Opal 2.0 – facilitates the implementation of data protection and compliance with security policies.
• Power Loss Protection (PLP) with internal backup power – protects against data loss or corruption during sudden power outages.
• MTBF 2 500 000 hours and Design life 5 years – designed for 24/7 load in critical environments.
• 7008TB TBW and data retention ~3 months at maximum TBW – clearly defined durability and end-of-life behavior.
• Support for TRIM/Deallocate, NVMe-MI, and SMBus, OCP 2.0 compatibility – easier management, monitoring, and integration into modern server ecosystems.

Who it is suitable for

The PM1743 is a logical choice if you are building or upgrading servers, storage arrays, HCI clusters, or critical services, where uptime, IOPS, and consistent latency are more important than the price per gigabyte. It is suitable for data centers, corporate environments, hosting, virtualization, and heavy database workloads. It is not particularly suitable for a typical home desktop or budget gaming build – the U.2 form factor and enterprise focus require the right platform to make sense.

The strongest aspect of this model is the combination of PCIe 5.0 speed, huge random IOPS capacity, and a full package of enterprise extras – dual-port, PLP, encryption, and strict TBW rating – all in a 3.84TB U.2 enclosure, ready for serious production environments.
