The TS-432X-4G shares the same basic design as the TS-464 that we reviewed in 2022, but this time around, the 6.6-by-6.6-by-8.9-inch (HWD) enclosure is black and silver rather than black and gold. The right side of the front panel holds status LEDs for power, LAN, USB, and drive activity. They are joined by a USB 3.2 Gen 1 Type-A port, a power button, and a One-Touch Copy button. Behind a removable front panel cover are four hot-swappable drive bays and tool-free drive sleds for 2.5- and 3.5-inch drives. As with most NAS devices, you’ll have to supply your own drives.

The rear panel has a 10GbE SFP+ LAN port, a pair of 2.5GbE LAN ports, a USB 3.2 Gen 1 Type-A port, and a power port. Finally, a covered low-profile PCIe slot will accommodate a 10GbE card or a dual M.2 expansion card. Unlike the Asustor AS6804T, the TS-432X-4G does not offer on-board M.2 slots for SSD acceleration. Also missing is the HDMI port that you get with the QNAP TS-464.

The TS-432X-4G is powered by a 2GHz AnnapurnaLabs AL524 quad-core CPU, 4GB of DDR4 RAM (which is expandable to 16GB), and 512MB of flash memory. It can accommodate up to 96TB of storage using four 24TB drives and supports RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, Single, and JBOD configurations. It also supports EXT4 file extensions and volume snapshots that capture a complete image of your NAS system so you can revert to an earlier version if problems arise. For more storage capacity, QNAP offers multiple tower and rackmount expansion units.
