QNAP TR-002-US 2-Bay USB 3.2 Gen 2 Direct Attached Storage Enclosure

Overview

The TR-002-US is a two-bay, 3.5-inch SATA direct attached storage (DAS) enclosure that connects to a host via USB 3.2 Gen 2 Type-C at up to 10Gbps. The onboard microprocessor handles hardware RAID natively — offloading parity calculations from the host — making it a practical capacity expansion option for workstations, NAS devices, or servers that need additional spinning storage without internal bay space. If you're running a single-bay QNAP NAS or a desktop workstation that's out of 3.5-inch slots, the TR-002-US adds two drives in a standalone enclosure without requiring a PCIe slot or additional power controller.

Compatibility

The TR-002-US connects to any host with a USB 3.2 Gen 2 (10Gbps) Type-C or Type-A port (with appropriate cable). It is directly compatible with the QNAP NAS lineup, including single-bay and multi-bay units that expose a USB expansion port — such as the TS-x53D and TS-x32 series — where it appears as an expansion shelf. It also pairs with Windows and macOS workstations as a standard USB mass storage device. Accepts two 3.5-inch SATA HDDs; 2.5-inch drives require a bracket adapter not included. RAID modes (0, 1, JBOD, and individual) are configured via the enclosure's hardware RAID selector — no driver or software installation needed on the host for basic operation.

Installation Notes

Operating temperature range is 0–40°C — standard indoor/office environment; not rated for unheated server rooms or outdoor enclosures. Net weight is 3.02 lbs (1.37 kg) unloaded; plan for an additional 1–1.5 lbs per populated 3.5-inch HDD. USB 3.2 Gen 2 Type-C cable is required for full 10Gbps throughput; a Type-C to Type-A adapter will drop the link to the host port's maximum speed. RAID mode changes require a drive format — migrate data off before switching RAID configurations.
