4-bay hardware RAID enclosure
The QNAP TR-004U-US is a 4-bay rackmount enclosure that uses a micro processor with hardware RAID to manage storage. It ships without drives so you can install your own 2.5-inch or 3.5-inch SATA disks. The unit connects to a host via a single Type-C USB 3.0 port running at USB 3.1 Gen 1 speeds. It is built for backup and media streaming through a personal cloud.
Check host port and drive count
Verify that your computer or server has an available USB Type-C or Type-A port compatible with USB 3.0 before ordering. The enclosure provides four SATA bays and includes twelve screws for 2.5-inch drives plus sixteen screws for 3.5-inch drives. A USB 3.0 Type-C to Type-A cable and a cable clip are supplied in the box. Ensure you have enough SATA drives to fill the desired RAID configuration.
Thermals noise and power draw
An open-frame 100 W power supply accepts 100 V to 240 V input at 50 Hz to 60 Hz. The operating temperature range is 0 °C to 40 °C with humidity tolerance of 5 % to 95 % relative humidity. The 1U form factor measures 1.73 inches high, 17.28 inches wide and 11.46 inches deep, allowing it to fit in standard rack cabinets.
