Description
The QNAP TR-004 is a robust 4-bay RAID expansion enclosure designed to bridge the gap between simple external drives and complex NAS systems. Utilizing a USB 3.2 Gen 1 Type-C interface, it offers a high-performance bridge for data backup and storage expansion across Windows, macOS, and Linux environments, as well as QNAP NAS units.
This product is for:
- Creative professionals needing high-capacity local storage for 4K video editing and large photo libraries.
- QNAP NAS owners looking for a cost-effective way to expand their existing storage pools or volumes.
- Small business owners requiring a reliable, hardware-controlled RAID backup solution for critical office documents.
- Home lab enthusiasts who want to experiment with different RAID configurations without taxing their primary server's CPU.
- Power users seeking a portable yet high-capacity storage vault that can be easily moved between different workstations.
Detailed specifications:
- Interface: USB 3.2 Gen 1 Type-C (1.0m cable recommended for optimal performance).
- Drive Bays: 4 x 3.5-inch SATA 6Gb/s, 3Gb/s (backwards compatible).
- Supported Drive Types: 3.5-inch SATA HDD, 2.5-inch SATA HDD, 2.5-inch SATA SSD.
- RAID Modes: Individual, JBOD, RAID 0, RAID 1/10, RAID 5 (Hardware or Software controlled).
- Security: Lockable drive trays with physical keys to prevent unauthorized removal.
- Special Features: One-touch copy button (with compatible QNAP NAS) and physical Eject button.
Setting up the TR-004 is remarkably straightforward thanks to the physical DIP switches on the rear panel, which allow for hardware-level RAID configuration without needing software. For those who prefer more granular control, the QNAP External RAID Manager utility provides a clear interface for monitoring disk health and RAID status on a PC. The build quality is industrial-grade, featuring lockable trays that ensure physical data security in shared environments. When connected to a QNAP NAS, it functions seamlessly as an expansion unit, allowing users to format it as a separate volume or use it for local backup.
Compared to standard single-bay external drives, the TR-004 offers significantly higher data redundancy through RAID 5 and RAID 10 configurations. While it lacks the standalone networking capabilities of a full NAS, it provides a much more affordable entry point for users who already have a powerful PC or an existing NAS and simply need more raw storage capacity. Unlike software-only RAID enclosures, the TR-004's dedicated hardware RAID controller ensures consistent performance without consuming host system resources.
Q&A:
- Can I mix HDDs and SSDs in the same RAID group? No, the TR-004 requires all drives within a single RAID group to be of the same type (either all HDD or all SSD).
- Does it support the QDA-A2AR or QDA-A2MAR adapters? No, the TR-004 is not compatible with these specific QNAP drive adapters.
- How do I safely remove the device from my computer? You can use the physical Eject button on the front panel, provided you have the External RAID Manager utility installed on your host system.
- What is the maximum cable length recommended for the USB connection? For optimal performance and stability, QNAP recommends using a USB cable no longer than 1 meter.
- Can the TR-004 be used as a standalone NAS? No, it is a DAS (Direct Attached Storage) device that must be connected to a host computer or a NAS via USB to function.
