Samsung PM1743 1.92TB E3.S (MZ3LO1T9HCJR-00A07) — PCIe Gen5 NVMe Enterprise SSD

Specifications

Overview

The Samsung PM1743 is Samsung's PCIe Gen5 enterprise NVMe SSD, and the MZ3LO1T9HCJR-00A07 is the 1.92 TB E3.S 1T build. E3.S (EDSFF 3-inch, short) replaces the 2.5-inch U.2 drive in newer 1U and 2U NVMe bays: it carries the same Gen5 x4 signalling in a much smaller envelope, so a chassis that holds eight U.2 drives can hold substantially more E3.S devices in the same rack unit.

Gen5 matters here for a specific reason. The PM1743's dual-port configuration lets two independent hosts address the same drive over separate PCIe lanes, which is what makes it suitable for clustered storage, active-active controllers, and any topology where a single drive must survive the failure of one host path. Combined with 2,500K IOPS random read, the part is aimed at AI inference data staging, vector databases and low-latency caching tiers rather than cold archive.

Every PM1743 in the QS Compute stock list is delivered with capacity, MPN and firmware revision verified against the manufacturer label before shipment.

Key Benefits

E3.S 1T density: fits high-density NVMe backplanes without the depth of a U.2 carrier. Dual-port Gen5: two-host access for HA storage controllers. 13,000 MB/s read: Gen5 bandwidth for AI data staging and caching tiers. Predictable 1 DWPD: five-year mixed-use endurance with published PBW.

Applications

AI inference data staging, vector-database and feature-store tiers, clustered NAS/SAN with dual-host controllers, high-density 1U/2U NVMe arrays, media caches, and database acceleration where read latency dominates.
