The TR-004-US is a 4-bay, hardware-based RAID expansion enclosure that connects via USB 3.2 Gen 1 Type-C — giving you a direct path to add up to four 3.5-inch SATA drives to an existing QNAP NAS or a Windows/Mac PC without modifying the host system. Because RAID is handled onboard (not by the host CPU), the enclosure offloads parity calculations and presents a single logical volume to the connected device — useful when you need expandable capacity on a NAS or direct-attached storage system without taxing the host. The TR-004-US is the US-market SKU; functionally identical to the TR-004 but ships with a US power configuration.
Designed to pair with QNAP NAS appliances that expose a USB 3.2 Gen 1 (or USB 3.0) Type-A or Type-C host port — including the TS-x53D, TS-x73A, TVS-hx88X, and TVS-hx77AX series, among others. Also functions as a standalone DAS enclosure connected to any Windows or macOS PC with a compatible USB 3.x port. The four bays accept 3.5-inch SATA HDDs; 2.5-inch SATA SSDs are physically compatible with the bay format. When attached to a QNAP NAS, the enclosure integrates with QNAP's Storage Manager for RAID configuration and monitoring. Confirm your specific NAS firmware supports USB expansion before purchasing — not all entry-level QNAP models expose USB storage expansion in QTS.
Hardware RAID mode is set via a physical switch on the enclosure — modes include JBOD, RAID 0, RAID 1, RAID 5, and single-disk. Set the RAID mode before populating drives and powering on; changing the mode after initialization requires a full rebuild and data loss. USB 3.2 Gen 1 delivers up to 5 Gbps throughput — sufficient for sequential NAS expansion workloads, but a practical ceiling to account for when sizing against RAID 5 write workloads across four drives. A compatible USB Type-C cable is required; verify cable is rated for USB 3.2 Gen 1 data rates, not charge-only.
