Samsung PM1733A 3.84TB (MZWLR3T8HCLS-00A07) — PCIe Gen4 Dual-Port NVMe SSD

Specifications

Overview

The Samsung PM1733A is the high-availability member of the Gen4 enterprise family, and the MZWLR3T8HCLS-00A07 is the 3.84 TB dual-port U.2 build. The distinguishing feature is not throughput but connectivity: in dual-port mode the drive presents two independent Gen4 x2 PCIe endpoints, so two separate hosts - typically the two controllers of an active-active array - can address the same physical device.

That single property is what lets an NVMe-based dual-controller array provide the same redundant-path behaviour that SAS offered natively for years. Without dual-port capability an NVMe drive has exactly one host path, and a controller failure means the drive is unreachable even though it is physically healthy.

Random read reaches 1,500K IOPS, the highest in the PM1733A line, which is what makes the part suitable for read-heavy database and caching tiers that also require redundant host paths.

Key Benefits

Dual-port Gen4: two independent host paths for active-active controllers. 1,500K IOPS random read: highest in the PM1733A line. 7.0 PBW: five-year 1 DWPD endurance. NVMe over SAS-like redundancy: HA storage without a SAS midplane.

Applications

Dual-controller all-flash arrays, NVMe-based HA storage clusters, read-heavy database tiers requiring redundant paths, caching layers, and mission-critical virtualisation datastores.
