Overview

The QNAP TR-002 serves as a straightforward storage expansion solution in a compact two-bay desktop form factor. Connected via USB 3.2 Gen 2 Type-C, it delivers transfer speeds up to 10Gbps, making it capable of handling large file transfers and serving as a responsive external storage volume. The enclosure accepts both 3.5-inch and 2.5-inch SATA drives, giving users flexibility to install traditional hard drives for capacity or SSDs for speed. A physical DIP switch on the unit allows you to configure RAID modes — including RAID 0, RAID 1, JBOD, and individual — without needing software, which is particularly useful when setting up the unit with a standard PC.

When paired with a compatible QNAP NAS, the TR-002 integrates into the NAS storage pool, effectively adding two more drive bays to your existing setup. When used as a standalone DAS with a PC, it functions as a standard external storage device with the added benefit of hardware RAID protection. Thoughtful design details include lockable drive trays that prevent accidental removal and a dedicated eject button for safe disconnection. The unit draws power from its own adapter rather than the USB bus, ensuring stable operation with spinning hard drives that demand consistent power delivery.

Pros & Cons

👍 Pros

  • USB 3.2 Gen 2 Type-C connection provides fast data transfer speeds up to 10Gbps.
  • Hardware DIP switch allows RAID configuration without any software, enabling quick setup.
  • Works as both a NAS expansion unit and a standalone DAS device for PCs.
  • Lockable drive trays prevent accidental drive removal in shared or active environments.
  • Compact two-bay design takes up minimal desk space while adding meaningful storage capacity.

👎 Cons

  • Limited to two bays, which restricts total storage capacity and RAID options compared to four-bay enclosures.
  • USB connectivity means it cannot match the throughput of direct SATA or network-attached configurations for heavy workloads.
  • No network connectivity of its own — it depends entirely on the host device for network access.
  • Does not include drives, so the total cost of a usable setup is higher than the enclosure price alone.

Frequently Asked Questions

It works both ways. You can connect it directly to a PC as a Direct-Attached Storage (DAS) device, or use it to expand the storage capacity of a compatible QNAP NAS. No QNAP NAS is required for basic use.
The TR-002 supports multiple configurations through its DIP switch, including RAID 0, RAID 1, JBOD, and individual disk modes. You can set these via hardware control on the unit itself or through software when connected to a QNAP NAS.
It accepts 3.5-inch SATA hard drives and 2.5-inch SATA drives (HDD or SSD). It supports up to two drives in its two bays.
The drive trays include a physical lock mechanism that prevents drives from being accidentally removed or dislodged. This is useful in shared environments or when the unit is positioned where it might be bumped.
The TR-002 includes a dedicated eject button on the unit itself, which safely disconnects the enclosure from the connected NAS or PC before you unplug the USB cable.
