QNAP TR-004-44W-US 4-Bay DAS 12TB WD Red Plus HDD Bundle

The QNAP TR-004-44W-US bundles the TR-004 four-bay DAS enclosure with four pre-installed 4TB WD Red Plus HDDs, pre-configured in RAID 5. The operational implication of that configuration: 9TB of usable space protected against any single drive failure, delivered over a USB 3.2 Gen 1 connection. The WD Red Plus drives are rated for NAS-class workloads — 24/7 operation, up to 180TB/year workload rating — meaning they're not consumer drives misassigned to continuous duty. The onboard hardware RAID controller is the critical differentiator versus a simple multi-drive enclosure: parity is calculated by the TR-004's dedicated chip, not your host CPU, which matters when the unit is connected to a workstation that's simultaneously under computational load.

This unit fits squarely in two workflows: direct-attached backup storage for a desktop or laptop workstation, and capacity expansion for an existing QNAP NAS via the USB-C port. For a video editor or photographer needing bulk storage redundancy without the complexity of a full NAS deployment, the TR-004 bundle answers the question cleanly — plug it in, it works. For the QNAP NAS user who has outgrown their internal bay capacity, the TR-004 connects directly to the NAS USB port and expands available storage within the QNAP ecosystem. What this is not: a network-accessible device. Without a host machine or NAS acting as the network bridge, the TR-004 serves only the directly connected computer.
