4-bay USB 3.0 RAID Expansion Enclosure

The TR-004 USB 3.0 RAID expansion enclosure allows you to expand the capacity of your QNAP NAS and PC. The TR-004 can also be utilized as a DAS (Direct-attached Storage) device, allowing you to directly access its content just by connecting it via USB. The TR-004 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.
Eject button for disconnecting the TR-004 from a NAS or computer*.
Instantly back up files from the TR-004 to the NAS using the One Touch Copy button**.

Effective storage expansion with RAID Support

The TR-004 is an ideal storage expansion solution for PCs, especially for laptops which lack the ability to install larger, higher-capacity drives. Featuring four 3.5-inch SATA drive bays and supporting RAID configuration, the TR-004 provides the ability to store a vast number of files and data and to ensure protection against potential drive failure.

Supports various RAID levels

The TR-004 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 space, allowing you to independently access each one.


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.

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

Use Storage & Snapshots Manager to configure the TR-004 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-004 as a DAS.

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

Versatile usage scenarios to meet storage expansion needs

The TR-004 meets many storage expansion requirements for home and work use, including:

Scenario 1 : Expand the capacity of your NAS

use the TR-004 instead of a conventional NAS expansion unit

Scenario 2 : External storage for your NAS

use the TR-004 as external storage for your NAS

Scenario 3 : Expand the storage space for your computer

use the TR-004 to provide more space for your computer

Scenario 4 : Cross platform file sharing

use the TR-004 to quickly move files between various devices with various file systems

Scenario 1: Expand the capacity of your NAS

The TR-004 provides an alternative method for users to expand their NAS storage capacity. By connecting the TR-004 to their NAS and using the Storage & Snapshots Manager, users can easily configure and manage their storage expansion. The TR-004 supports a variety of QNAP NAS storage and file management functions, allowing users to build storage pools, find files with Qsirch and organize files with Qfiling.

Use the TR-004 as an alternative to conventional NAS expansion enclosures

As an external hardware RAID device, the TR-004 operates independently and does not require additional NAS system resources. When compared with the UX-500P expansion enclosure, the TR-004 uses less NAS system resources.

Scenario 2: External storage for your NAS

Instead of using the TR-004 to expand the capacity of your QNAP NAS, you can use it as a complimentary storage unit for backing up or moving data. It also allows you to physically migrate huge data collections that would require significant network bandwidth. While connected to the NAS, you can monitor the health and status of the TR-004 by using the Storage & Snapshots Manager on the NAS.

Scenario 3: Expand the storage space of your computer

The TR-004 can quickly add storage space to your computer. You can use the DIP switch to configure a hardware RAID mode or manage it by using the QNAP External RAID Manager utility. The health and status of the TR-004 can also be monitored by using the QNAP External RAID Manager utility.

Scenario 4: Cross-platform file sharing

From your NAS to Windows, Mac, and Linux computers, the TR-004 is compatible with a wide range of devices. This makes it ideal for quickly moving large files between different devices. The TR-004 is even compatible with devices that use the exFAT file system*, adding further convenience for accessing and sharing files from a wider range of devices.

    Which is better between Synology and QNAP

    Both of them are great NAS brands – the top in the NAS category . This question is like which is better- iOS or android. Typically QNAP offers more hardware choices and hardware tweaking options. Synology on the other hand has more stable and easier software UI. The one you should go for , greatly depends on the actual requirement you have.

    How do I shut down QNAP NAS
    If you have the admin access to the web interface, then select shut down from the power menu. If not, press the power button for 1.5 seconds till you hear a beep. On doing this the system starts the shutdown process ( and it shows so on the LCD screen if your NAS has one). It takes about 5-7 minutes for the system to stop services, unmount volumes and then shutdown safely. If you want to shutdown immediately, then keep the power button pressed for 5 seconds – this is equivalent to pulling the power and may corrupt the volumes though.

    Which QNAP NAS is good to buy
    QNAP has a model for almost every single processor available so the choice of NAS is overwhelming. Generally 51K, 51+ and 53D are very popular models. Decision on which model to buy will greatly depend on what you want to use your NAS for, and your budget.

    How Does QNAP NAS work
    All the Major NAS work the same way. At the very basic – you connect them to a network, define basic permissions and settings and then anyone on your network ( or outside the network if you configured cloud) can access it on PCs and mobile devices. Contact us if you want to see a demo

    How do I use QNAP NAS

    What is Thick Volume in QNAP
    With QNAP thick Volumes you specify the total volume space at the time of creation, and that much space is actually set aside for your volume. This is in contrast with Thin volume where the volume expands to take as much space as it needs , providing overprovisioning. Use thick volume if you want to keep guaranteed space aside for your volume

    You can set the maximum space allocated to Snapshots. Typically it should be 20-30%. The actual space the snapshots occupy depends on how much snapshot data differs from actual data on disk.

    qnap how to replace failed drive
    Drives are hot swappable which means you don't have shut down the unit. If you are on RAID 5 , then you only have 1 HDD failure tolerance, and it's advisable to not use the NAS while the RAID is being rebuilt. Replacing hard drive is as easy as pulling the bay housing the failing/failed drive, and replacing with a new drive.
