QNAP Launches the TR-004, a 4-bay Hardware RAID Storage Expansion Device for both PC and NAS

  • Reading time:3 mins read

QNAP launched the TR-004, a 4-bay hardware RAID storage expansion device that can be attached to PC or NAS via USB 3.0 Type-C. The multipurpose appliance can be used to add storage space to a QNAP NAS, and can also serve as hardware-based RAID storage for PCs and NAS. The appliance offers convenient cross-platform file sharing and high flexibility for users, acting as a high-efficiency and intuitive storage expansion option.

The TR-004 supports individual, JBOD and RAID 0/1/5/10 storage configurations. QNAP NAS users can use the enclosure with their NAS, including setting RAID parameters and creating a storage pool by using the “Storage and Snapshots” app within QTS. Alternatively, the system can be used as an external storage device of the NAS. It can also be used with computers to facilitate file sharing and exchange, and supports the exFAT file system. Computer users with limited storage upgrade options can also use the TR-004 as an expansion unit, and a specialized QNAP External RAID Manager utility (Windows/macOS) can help them view disk health, change RAID configurations, check logs, and update the firmware of the TR-004.

Jason Hsu, Product Manager of QNAP, said: “The TR-004 is a new option for NAS and DAS expansion, with a single device being available in two realms. While existing QNAP NAS users can add storage space to their NAS with the TR-004, PC users can purchase the device, acquire a NAS at a later time, and keep using their TR-004 for maximum cost efficiency.”

A DIP switch on the rear can switch the disk configuration of the device. There are also status indicators, a one touch copy button and an eject button to make operations more intuitive. When the host PC/NAS goes to sleep, shuts down, or is disconnected, the unit will go into the sleep mode and save energy. For compatible QNAP NAS models and usage scenarios, please visit
