Expert Review Analysis

The QNAP TR-004U is a 1U rack‑mountable 4‑bay RAID expansion enclosure that connects via USB 3.2 Gen 1 Type‑C to QNAP NAS devices, PCs or servers. It offers flexible RAID options, hot‑swappable drives, and a compact design for data‑center rack environments.

✓ Best for: QNAP NAS administrators, data‑center or server environments needing a compact 1U storage expansion, backup and migration tasks, and media professionals requiring high‑capacity local storage across Windows, macOS and Linux platforms.✗ Not ideal for: Home users or small offices that need network‑attached storage with built‑in Ethernet, or scenarios demanding faster than USB 3.2 Gen 1 throughput such as high‑speed video editing over multiple drives.

Pros

✓Supports multiple RAID levels (0, 1, 5, 10, JBOD) with hardware DIP switches for flexible storage configurations
✓Hot‑swappable, lockable 3.5‑inch and 2.5‑inch SATA drive trays simplify drive replacement and improve security

4.3

(348 reviews)

Compact 1U rackmount form factor with short depth fits easily into standard data‑center racks

✓Cross‑platform compatibility works with QTS/QuTS hero, Windows, macOS and Linux hosts

Cons

✗Limited to USB 3.2 Gen 1 (5 Gbps) which can become a bottleneck for high‑performance RAID arrays compared to internal SAS or Ethernet connections
✗No built‑in network interface; relies entirely on the host computer’s USB connection for data access
✗Power consumption reaches nearly 19 W in typical operation and requires a 100 W open‑frame power supply, adding to rack power density

How It Compares

vs. QNAP TR-004 (tower model)

Advantages

✓Smaller and lighter (1.85 kg) making it easier to place on a desk
✓Lower power consumption (65 W) and quieter operation (18.1 dB(A))

Disadvantages

✗Desktop tower form factor not suitable for rackmount data‑center deployments
✗USB 3.0 Type‑C interface provides lower theoretical bandwidth than the TR-004U's USB 3.2 Gen 1

Choose the TR-004U for rackmount, high‑capacity enterprise use; choose the TR-004 for desktop or quieter, lower‑power scenarios.
