QNAP TR-004U-US Specifications

    4-Bay 1u 12 inch Short Depth Rack Maintenance 3.5 inch SATA USB3 Typec RAID Enclosure


    Rear View

    The TR-004U USB 3.0 RAID expansion enclosure allows you to expand the capacity of your QNAP NAS and PC. The TR-004U can also be utilized as a DAS (Direct-attached Storage) device, allowing you to directly access its content by connecting it via USB. The TR-004U features four 3.5-inch SATA drive bays with multiple RAID configuration options and USB 3.0 Type-C connectivity to bring you a highly-reliable and secure storage capacity expansion solution.

    USB 3.0 Type-C port for faster data transfer.

    Supports up to four SATA drives for reliable read and write performance.

    Disk mode DIP switch to change from Hardware Control and Software Control configurations for setting RAID group.

    Lockable hard drive trays to prevent accidental drive removal.

    Users can configure RAID and monitor disk health using Storage & Snapshots Manager on a QNAP NAS.

    Can be used to add storage space to a QNAP NAS, serve as hardware-based RAID storage, and offers cross-platform file sharing for users.

    Supports various RAID levels

    The TR-004U supports a variety of RAID configurations. Depending on your requirements, you can switch between hardware- or software-controlled RAID modes. Move the DIP switches to corresponding positions for your ideal RAID mode: Individual, JBOD, RAID 0, RAID 1/10 or RAID 5. You can also configure the RAID settings from your QNAP NAS, or by using the QNAP External RAID Manager utility on your computer. Individual Mode

    Treats every disk as separate storage spaces, allowing you to independently access each one. JBOD Mode

    All the disks are recognized as a single drive. This allows maximal storage utilization but provides no data protection. RAID 0 Mode

    Data is split amongst the drives. RAID 0 provides the fastest performance but does not protect data from drive failure. RAID 1/10 Mode

    Half of the total storage capacity is used to store data, and the other half keeps a copy of this data. This provides high data protection at the cost of only being able to use half the installed storage space. RAID 5 Mode

    RAID 5 requires at least three drives to use and parity information is distributed among the drives, providing optimized storage capacity and protection against one disk failing. Software Ctrl Mode

    Use this mode to control the RAID configuration from your NAS or computer.

    Flexible storage configuration and management

    Compared with other RAID enclosures, the TR-004U provides software-controlled configurations for greater management flexibility. Users can configure RAID and monitor disk health using the Storage & Snapshots Manager on a QNAP NAS, or by using the QNAP External RAID Manager utility on their computer.

    QTS Storage & Snapshots

    Use Storage & Snapshots Manager to configure the TR-004U as a storage expansion unit for your QNAP NAS. In addition to RAID configuration, the NAS expansion storage mode supports various NAS functions, including storage pools and snapshots. By choosing external storage mode, you can use the TR-004U as a DAS.

    QNAP External RAID Manager

    The QNAP External RAID Manager is a utility for Windows and Mac users to set up, monitor, and view the status of the TR-004U. Users can easily configure RAID groups on the TR-004U and quickly obtain the status of RAID performance and health at a glance.
