QNAP TR-004 4 Bay USB Type-C DAS with Hardware RAID (Diskless)

The TR-004 is a multiple voltage compatible device, with a voltage range of 100-240V. It connects to Windows, macOS, and Linux systems via a USB Type-C direct-attached storage device. The product can be used as external storage for NAS backup, and it can also be used to expand the capacity of your QNAP NAS.

The TR-004 features four 3.5-inch SATA 3Gb/s (diskless) drive bays and supports hardware RAID configurations, including RAID 0, 1, 5, JBOD, and individual disks. The device includes a USB Type-C to Type-A connector cable for easy connectivity.

One notable feature of the TR-004 is its lockable drive bays, which provide added security for your data. However, it's important to note that the TR-004 does not support the following NAS models: TS-128, TS-228, TS-131, TS-231, TS-431, TS-431U, and any NAS models that cannot be updated to QTS 4.3.6 or later.

Additionally, the TR-004 can only be used as an individual storage pool or volume on the NAS, and its storage pool/volume cannot be combined with the connected NAS. NAS applications cannot be installed on the TR-004, and drives can only be migrated from one TR-004 to another TR-004. The files and data stored on drives moved to/from a NAS (or another device) will not be recognized.

In summary, the TR-004 is a versatile and flexible storage solution that can be used to expand the capacity of your QNAP NAS or as an external storage device for NAS backup. Its multiple voltage compatibility, hardware RAID support, and lockable drive bays make it a valuable addition to your storage infrastructure, though it does have some limitations in terms of compatibility and integration with certain NAS models.
