General Features

Effective Storage Expansion with RAID Support

The TR-004 is an ideal storage expansion solution, especially for laptops which lack the ability to install larger, higher-capacity drives. Featuring four 3.5" SATA drive bays and supporting multiple RAID configurations, 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 desired 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, allowing you to independently access each one. In JBOD mode, all disks are recognized as a single drive, which allows maximum storage utilization, but provides no data protection. RAID 0 splits data among the drives and provides the fastest performance, but does not protect data against drive failures. RAID 1/10 uses half the total storage capacity to store data and the other half for 1:1 data redundancy. This provides high data protection at the cost of only being able to use half the installed storage space. 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. All of these RAID modes are hardware controlled, but there is also a Software Control mode to configure the RAID 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.

Note: When connecting the TR-004 to a NAS, users can choose to use either the NAS expansion storage mode or the external storage mode.

Versatile Usage Scenarios to Meet Storage Expansion Needs

The TR-004 meets many storage expansion requirements for home and work use, including expanding the capacity of your NAS, serving as external storage for your NAS, expanding the storage space of your computer, and cross-platform file sharing.

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.

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 is good 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.

Note: To access devices that use the exFAT file system, users must purchase a separate exFAT driver license.

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.

If I connect this to my existing QNAP TS-431K ...

If I connect this to my existing QNAP TS-431K which is powered by an APC UPS, will the TS-431K signal the TR-004 to power down when street power is lost?
Asked by: Robert
The main NAS and the external enclosure have to be connected to the UPS. Otherwise if there is a total power loss, the TR-004 would just turn off like any other device and you will be sad. When both are connected to the UPS with the NAS is configured to shutdown upon power loss, it will in turn signal the TR-004 to power off as well. I have both mine configured this way and it’s worked on at least 2 occasions already. Clean shutdowns and no data loss or volume corruption.

Can I use the TR-004 as a DAS without RAID configuration, load disks already formatted for Mac with data on them and remove a disk for used on an external dock? I'd like to remove disks for my off-site backup purposes.
Asked by: Peter
Yes, however the preformatted drives would be reformatted again to JBOD. Each time you would also have to power down the device to make modifications.

I can not get this thing to mount. It doesn't appear in the Disk Utility. It the QNAP software kind find it. It keeps spooling up and shutting down repeatedly. I'll get "Disc Not Ejected properly" messages. What's with it?
Asked by: A.
I had no problems. If few more suggestions - The lights on the front of the device are helpful. If you have a good USB connection to your computer the "USB" light will be blue. All the other lights will be solid green for the power and each drive inserted. If you have a disk that is being built, both the Ready light and HDD light for that disk will alternate between green and red (or orange - I don't remember which). Note, for each RAID group you are going to set up, the drives should be identical. - Assuming all the lights are correct for the disks you have installed, try plugging into a different USB port (especially, prefer to plug the device directly to the PC rather than some external hub) - At this point, the QNAP External RID Manager software should be able to detect the device and find it. Using the "Action" dropdown, select "Locate" and the device will start beeping and you will know you have a connection between the PC and the device that can interact. - The use the RAID manager to verify the types of drives you have installed

I'm currently using a 14TB external drive for Time Machine backup on my Mac. Can I remove and insert that hard drive into the QNAP and add another 14TB disk and use it as JBOD, or do I have to copy the Time Machine data and reformat the 2 drives?
Asked by: Richard
It is recommended instead that you install drives that are certified compatible with the TR-004. You can then migrate the Time Machine backup to the TR-004.

Do you need to insert 4 drives off the bat, Or can you start with let's say 2? And if you can start with 2, do have to add 2 more at the same time, or can you add a 3rd, and then wait a while(like a year) and then add a 4th?
Asked by: eric
I believe you can start with just one. Personally I’m running two in RAID 1 via the dip switches on the back. They give the ability to run software RAID as well.
