QNAP TR-004 Raid Expansion Enclosure Review – What’s in the Box?

We got our hands on the QNAP TR-004 just recently and it arrived in a rather simple retail box which was, of course, branded. The company gave it a nice touch despite it being simple. Also, , they were able to do away with such a design for the package since a majority of users who’d be purchasing this would be QNAP users currently having their own capacity requirements. So even if QNAP’s NAS expansion packages aren’t really that exciting or eye-catching, the boxes are quite useful in a way.

When you open the package, you’ll immediately see the TR-004 RAID Expansion Enclosure which is set securely in place. Aside from the TR-004, other items that are present in the box include an AC power adapter, a USB Type C to Type A connecting cable, a power cord, 2 drive tray keys, a USB cable clip, a total of 16 screws for the 3.5-inch drives, as well as 12 screws for the 2.5-inch drives. Of course, QNAP also included a quick installation guide to make the entire process of installing easier on your part.

QNAP TR-004 Raid Expansion Enclosure Review

When we finally got the TR-004 RAID Expansion Enclosure out of its box, we were met with a very familiar exterior for it’s casing. We’ve already seen this type of plastic chassis used for other QNAP NAS devices and we really don’t mind this at all.

The front portion of the product features a total of 4 plastic hard drive bays, as well as numerous LEDs; things that you would see on a NAS device that denotes a system and drive access, plus health and notification for any kind of issue. Unlike the older QNAP NAS expansions, the TR-004 has a more compact and less noticeable design which can easily blend with your environment.

If you take a look at the trays of the TR-004 RAID Expansion Enclosure from QNAP, they sport a screwless design with a body made entirely of plastic. Though it is worth noting that if you plan to utilize SSD or higher capacity 14 or 16TB HDDs, you won’t have to worry about connecting them since the package includes the necessary accessory pack for installation. Additionally, its bays can be locked to avoid any unwanted, intentional, or accidental removal. When you look at the base of the TR-004, you’ll notice its ventilation set along the base of the device. The company positioned the vents in this area to better assist active airflow and to allow it to work as an extra ventilation bay located at the side of the product. This greatly helps air travel through and over the inner RoC.

If you flip the device, you’ll find that it’s really similar to the QNAP NAS, but the difference between the two is that the TR-004 lacks the LAN / Network / RJ-45 connectivity. This product, although it offers its own RAID 5 / 6 handling, needs a link to the NAS to be able to boost your current RAID. Yet another interesting aspect about the device is that it can be utilized as a USB RAID 5 and 6 storage for standalone utilization with Mac, Windows, or Linux computers. Similarly, if you have the RAID for your PC or Linux in a general file system, you can easily disconnect this and instead, connect it to a NAS device to make all of the contents available from your NAS and other shared network devices.

The USB connection of the device is a USB Type C, though it does make use of the USB 3.1 1st Generation, it still comes in handy compared to the USB Type A. This makes it compatible with the new systems that have changed to a more practical connection. The accessory pack that comes with the device has a USB Type A to C cable which is necessary for linking the TR-004 to your NAS / Mac / computer using a classic USB Type A. For the RAID, there are a collection of dip switches located on the rear portion of this product. These are utilized for setting the hardware functionality of the RAID.

Details of each configuration have been designated on the information panel located on the TR-004. This will assist you in configuring the proper RAID setup just for you. After, you can power up the device which will establish a RAID environment that will go across the present drives. This is generally the primary reason why the TR-004 RAID Expansion Enclosure from QNAP is an interesting device for the NAS. Until now, every expansion chassis for the NAS concerns the NAS’ CPU supporting and creating an existing raid on them. This results in the CPU having to work more to maintain the storage environment, and this, in turn, greatly influences the read and write speeds.

Not only that, but if the RAID is controlled by the NAS devices and it suddenly gets disconnected in error from the host storage because of a power outage, it can clearly damage both the original NAS RAID and the expansion storage. So, to eliminate and prevent this issue, having a NAS expansion like this TR-004 Raid Expansion Enclosure is the best option. Of course, you will still need to treat your storage adequately, yet the handling of the external RAID only means that it will be able to handle sudden disconnections better; plus, it will also have boosted read and write speeds from having a RAID handling chip.

The TR-004 RAID Expansion Enclosure lets you easily increase the capacity of your PC or QNAP NAS device. Not only that, but it can also be used as a DAS or direct attached storage device which will allow you to immediately access contents simply by linking it with a USB.

The TR-004 has a total of four 3.5-inch SATA drive bays along with a couple of RAID setup options; it also has a USB 3.0 Type C connection to provide you with a more reliable and protected storage extension solution. What makes the TR-004 efficient is that it is equipped with a DIP button at the back panel of the device. It works by altering the disk setup of the device. Other notable aspects of this device include the single-touch copy button, status indicators, and the eject button.

The TR-004 RAID Expansion Enclosure also supports JBOD, individual, and RAID 0 / 1 / 5 / 10 storage setups. All QNAP NAS users can utilize the TR-004 together with their NAS devices when it comes to making a storage pool. This is by utilizing the Storage and Snapshots application that is in the QTS. Alternatively, it can also be used as an external storage of the NAS, can be used with PCs to further promote file exchange and sharing, while supporting the exFAT system as well.

If you are a PC user that has a limit when it comes to storage upgrade choices, then you can also utilize the TR-004 RAID Expansion Enclosure as an expansion unit. Also, a special QNAP External RAID Manager utility can aid these users change RAID setups, view disk health, check logs, and also update the TR-004’s firmware.

When it comes to power consumption, the HDD on standby is at 4.17 Watts while it goes up to 18.21 Watts during operations. For its operating temperature plus the relative humidity, the TR-004 is from 0 ~ 40°C, 5 ~ 95% RH. When it comes to the compatibility of the QNAP TR-004 RAID Expansion Enclosure, it can work with the 3.5 and the  2.5-inch SATA 6Gb/s, 3Gb/s; also, it is compatible with the 2.5-inch SATA 6Gb/s, Solid State Drives.
