QNAP TR-004U-US 4-Bay 1U 12" Short-Depth Rackmount, 3.5" SATA HDD

Expand and protect your surveillance storage with the QNAP TR-004U 4-Bay 1U rackmount expansion enclosure. Built for video surveillance servers and NVR deployments, this QNAP DAS lets you add up to four 3.5" SATA drives via a USB 3.0 Type-C host interface for fast ingest and playback of high-resolution camera streams. The compact 1U, short-depth design (about 12" depth) fits shallow racks and tight monitoring closets, making it ideal for security, monitoring and edge installations. Switch between hardware-controlled RAID and software-controlled RAID modes (RAID 0/1/5/10/JBOD) with a DIP switch or manage groups from your QNAP NAS using Storage & Snapshots Manager or the QNAP External RAID Manager utility. Lockable trays protect drives from accidental removal, and integrated health monitoring helps prevent data loss of mission-critical footage. Whether you need more retention days, faster archive exports, or a resilient RAID target for your NVR, the TR-004U delivers flexible, rack-friendly expansion for security and surveillance environments. Scale your recording capacity and secure video evidence—deploy the TR-004U for your next monitoring upgrade.
