The QNAP TR-004 turns any computer into a mini data center. This 4-bay direct-attached storage unit connects via USB Type-C and gives you hardware RAID protection without needing a full NAS setup. You get enterprise-grade data redundancy on your desktop, which means your files stay safe even if a drive fails.
What makes this stand out is the hardware RAID controller built right in. Your computer doesn’t waste CPU cycles managing RAID arrays—the TR-004 handles it all. You can configure RAID 0 for speed, RAID 1 for mirroring, RAID 5 for balanced protection, or run drives individually. The lockable drive bays add physical security, and the included USB-C to USB-A cable means it works with older systems too.
Who Is This For?
This is perfect for photographers and video editors who need fast, expandable storage that travels between workstations. It’s also ideal if you already own a QNAP NAS and want dedicated backup storage or capacity expansion. Creative professionals will appreciate the ability to hot-swap drives without opening a computer case. If you’re running Windows, macOS, or Linux and need more than a single external drive can offer, the TR-004 delivers professional-grade storage without the complexity of a full NAS.
Bottom Line
The TR-004 gives you four-bay RAID protection in a compact desktop unit. You supply the drives, it supplies the redundancy and speed. The hardware RAID means consistent performance regardless of your computer’s specs. Just know this arrives diskless, and if you’re pairing it with a QNAP NAS, check compatibility first—some older models aren’t supported. For anyone who needs reliable, expandable storage that doesn’t require networking knowledge, this is a solid choice that just works.
