4-bay 1U rackmount NAS

The Qnap TS-432PXU-2G-US is a 1U rackmount network-attached storage server with four SATA drive bays. It runs on an AnnapurnaLabs Alpine AL324 quad-core ARM Cortex-A57 processor at 1.7GHz with 2GB of installed DDR4 memory. The unit includes a 250W power supply and operates at a typical 39.558W.

Network connectivity and expansion

Two 10GbE RJ-45 ports and two 2.5GbE RJ-45 ports provide high-speed wired networking for backup and media streaming. Four USB 3.2 Gen 1 ports allow direct attachment of external drives or peripherals. A single PCIe Gen2 x2 slot is available for add-in cards such as additional network adapters. Builds that require 10GbE SFP+ transceivers or a redundant power supply cannot use this model.

DDR4 SODIMM memory limit

The system ships with 2GB of DDR4 RAM in one SODIMM slot and supports a maximum of 16GB total capacity. Buyers planning virtualisation workloads or heavy multi-user access should budget for a memory upgrade before deployment.

Questions about this item

What bandwidth does the 10GbE RJ-45 interface cap at?

Each of the two 10GbE RJ-45 ports caps at ten gigabits per second.

Which drive form factors fit the four bays?

The four bays accept 3.5-inch SATA hard drives, 2.5-inch SATA hard drives and 2.5-inch SATA solid state drives.

How is a memory upgrade installed and what step is often missed?

Power off the NAS, open the chassis, insert one DDR4 SODIMM module into the single slot, close the chassis and power on; the step often missed is fully seating the module until the retention clips click.
