Qnap TS-462A-4G-US 4-Bay NAS 4GB DDR4

Four-bay personal-cloud NAS

The Qnap TS-462A-4G-US is a diskless desktop NAS with four SATA bays for 3.5-inch hard drives or 2.5-inch SSDs. An Intel Celeron N5095 processor and 4GB of DDR4 memory handle file serving, backup and media streaming for home or small-office users. Two SODIMM slots allow expansion up to 16GB when workloads grow. The unit ships without drives so you choose the capacity that fits your library.

Storage headroom and memory limits

Four drive bays give room for multi-terabyte arrays while two M.2 2280 PCIe Gen 3 x 1 slots add cache or fast metadata tiers. The installed 4GB DDR4 is sufficient for everyday streaming and backup tasks; heavier virtualization or database loads will hit the 16GB ceiling. No drives are included, so usable capacity depends entirely on the disks you install. The 2.5GbE port can become a bottleneck when multiple clients pull large media files simultaneously.

Connectivity and daily operation

A single 2.5GbE port links the NAS to the network, while two USB 2.0 and two USB 3.2 Gen 2 ports attach external drives or a UPS. Front-panel LEDs show power, LAN, USB and per-bay drive status at a glance. The 65W external adapter runs on 100-240V input, keeping the chassis compact and quiet. Operating temperatures from 0 to 40 °C suit typical indoor environments; the system is not designed for dusty or unconditioned spaces.
