QNAP TR-004 4-Bay USB Type-C Direct Attached Storage with Hardware RAID

A four-bay USB 3.2 Gen 1 Type-C external enclosure with a built-in hardware RAID engine that works as direct-attached storage with a QNAP NAS or a Windows, Mac or Linux computer.

Why people pick it

  • Hardware RAID 0, 1, 5 and 10 built into the enclosure, so the host computer does not have to do the RAID work
  • Four hot-swappable bays in a tower that works with QNAP NAS boxes and ordinary Windows, Mac and Linux PCs
  • Runs from a single USB Type-C cable and a 60W adapter, with a 120mm fan

Know before you buy

  • USB 3.2 Gen 1 (5 Gbps) link caps real throughput below what four modern drives can do together
  • Drive slots are SATA 3Gb/s, so per-drive speed is limited even with SATA 6Gb/s drives installed
  • Ships without drives, and only one disk type (HDD or SSD) can go in a single RAID group
