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.

QNAP TR-004 External HDD/SSD Reviews

Very fast and easy software

By Yves
Rated 5 out of 5
Date: 2022-09-25

Very fast data transfer, perfect for 4K HQ. Unlike Synology NAS the software and installation is very easy. I bought this NAS to replace a Synology DS2180 that was way too slow for file transfer and 4K streaming. I was able to install four RED NAS 8TB hard drives to make two RAID 1 on the GNAP TR-004 .

Works fine. Managing it is a pain

By Bruce
Rated 2 out of 5

There is only one port: a USB-3 port. The specs for managing the unit are not published, so you can only manage it with their proprietary software. If you use Linux, you're out of luck. Windows and Mac only. Also, if a new drive is detected, it will automatically reformat the disks, so when one drive fails, be careful to hot swap the drive and not to power off. Be careful.

good for adding onto existing QNAP RAID

I have a 4 slot QNAP RAID that was getting filled up after several years of use. The expansion unit I was expected to move too was no longer sold. This unit was made to replace. Not the best as its SATA-3 and is really not a full feature RAID. The built quality of is cheap with mostly plastic components when my existing QNAP is mostly metal. New generation home QNAP units looks to be built on cheaper parts. I decided to buy it as it allows my existing QNAP to manage it. It was on sale and made it a simple option till I replace my NAS option which may be a truenas or other option. The support from QNAP has been average and nothing to say I will definitely buy it again. B&H was very efficient from order to delivery and would definitely buy from them again.

I got 4 x 4TB drives installed. The only complaint is that the trays are flimsy and the locking mechanism is garbage.

The enclosure is excellent for back up photos and videos. I used individual mode with 4 disks and raid 1. The das is silent and reliable. The only limitation is the enclosure is SATA 2 speed limiting to about 200MB /s max. But for backups, it's enough

Great value for its price

By Thomas

A 4-bay RAID capable enclosure for this price is truly a great value. Admittedly, connected through USB-3.2 Gen 1, it is surely slow for a high traffic professional storage. But for a home-based large volume storage the solution is just right. I placed four 16TB drives in the enclosure and configured them to RAID-5. Using Windows 10, I formatted it to a virtual drive, and all this went without a hitch. 46.3TB in size, fantastic. QNAP has some issues with its firmware, but these are minor problems. For example, it took me a better part of one hour to install a firmware upgrade. The reason was a quite ambiguous translation to English (restart meat really power down and power up. Also by a seldom coincidence, one of my 4 drives was defective. And of course, I placed it in the 1st bay. QNAP never managed to boot due to this defective drive. I heard only never ending click-click-click noise, and I saw no progress. Only when I removed the drive, the device booted. And so I identified the defective drive. But when I tested this drive in my Dell workstation, the firmware correctly caused a timeout, and displayed a defective drive message. I am sure that a less experienced user would be perplex, and maybe even tried to return the QNAP enclosure. Furthermore, once I received a replacement for the 4th defective drive, I found no possibility to add it to existing 3-drive RAID 5 setup. I had to reformat the RAID5 drive and restart the backup from the beginning. Thus please be aware of the small limitations in the TR-004. Still, I am a happy camper, and I think that for the price user gets a great value without an alernative.

This thing is SLOW

By John

I bought this as a stand alone RAID unit, connected directly to a computer. While I appreciated the hardware RAID, and the software was easy to use, the fastest transfer speed I could clock was 180MB/s in any of the RAID configurations. That's with four X18 drives installed. I was expecting well over 400MB/s with that configuration in RAID 5.

Can I use the TR-004 as a backup drive for my Synology DS920+ via USB?
Asked by: Richard
Once the raid is configured, the TR004 acts as a conventional USB external drive, with no additional driver required. I configured it as RAID10 and using as a plain vanilla USB external with Windows 10. Ergo, if your DS920+ supports external USB drives for backups it should work.

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.

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
