QNAP TR-004 4 Bay Desktop NAS Expansion - Optional Use as a Direct-Attached Storage Device

Product Information

From people's experience here and what I've seen, I'd almost have to conclude that TR-004 shall have never been advertised as it can be used as a NAS storage (for its poor performance with RAID 5), as was described in the product manual and the advertisement video https://live.qnap.com/en/video/show/2430 or on youtube https://www.youtube.com/watch?v=I5_ahKpjF6A. But I do hope there is a solution that can make TR-004 as a NAS storage pool with RAIDs truly functional. When I'm testing over network, I'm using a 8GB and a 33GB .mkv file, copying to/from NAS to my PC's Samsung 960 EVO to make sure the drive in my PC is not skewing results.

The TR-004U can only be used as an individual storage pool or volume on the NAS. Its storage pool/volume cannot be combined into the connected NAS. NAS applications cannot be installed on the TR-004U.

Versatile usage scenarios to meet storage expansion needs

Individual, JBOD, hardware RAID 0/1/5/10, Software CTRL (Software control mode is for use with QNAP NAS and Windows/macOS utility) 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. Function did install 4 hdds into tr004 and setting up a raid5? and what is it's current setup like with the 2 existing hard drives on the tr-004?

Note: Use only QNAP memory modules to maintain system performance and stability. For NAS devices with more than one memory slot, use QNAP modules with identical specifications. Reformatted using the Software RAID 5 this time. Same slow issues. Then I switched to the 1m USB 3.0 C to A cable that came with the tr-004 and the "Type" shows up as "USB 3.1 Gen1". Now I get about 275 MB/s sustained writes, and still at 800 MB/s sustained reads utilizing SMB. Slows down to about 260 MB/s writes and 570 MB/s reads via AFP. All of that is with Jumbo Frames (9000). When I was on the phone with QNAP, the tech had me try Standard (1500). With that setting the Writes are the same, but the Reads slow to 415 MB/s over SMB. Reads increased to 650 MB/s over AFP with Standard (1500). For myself i just power off my external tl-d400s. My nas is setup for 24/7 that never spins down, because my usage patterns would probly trigger spinups/downs too frequently, so my case it's probly not worth it. also i'm not aware if whether my own device can keep the tl-d400s in a spindown state when it's not even doing anything, so i just use the power off just to be sure.OR alternatively you can set it up as a raid5 on standalone mode using the windows qnap utility app that can create the raid5 without using qts. I believe that you can still connect this to the QNAP and use as an external USB. But whenever you want to manage it, you need to connect to a windows pc and use the qnap utility app for tr-004 i presume. When connected to a Windows 10 and configured in RAID 5 (formatted as HFS): read/write at 190MB/s - 200MB/s I haven't seen a solution in this thread, and I have the same issue since I have had the TR-004 in September. My configuration and use case are as follows: At 512KB I/O Size and larger, RAID 0 and RAID 10 achieved right around 225-230 MB/sec write and 245 MB/sec read, with 4KB at about 22 MB/sec write and 25 MB/sec read. JBOD, which effectively is single drive speed at 64KB and above hovered around 175 MB/sec write and read speed, with 4K at about 25 MB/sec for both read and write. Second, when I perform a write operation against the drive, while I perform a read operation, the speed of the read drops to ~40MB/s while the write is around ~30-40MB/s. Seems like a pretty severe penalty that shouldn't be the case.

Drives can only be migrated from one TR-004U to another TR-004U. The files and data stored on drives moved to/from a NAS (or another device) will not be recognized.

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. QNAP reserves the right to replace partial parts or accessories if the original is no longer available from its manufacturer/supplier. Any replacement would be fully tested and verified to meet strict compatibility and stability guidelines and will deliver identical performance to the original. The TR-004 does not support the following: the TS-128, TS-228, TS-131, TS-231, TS-431, TS-431U, and NAS models that cannot be updated to QTS 4.3.6 (or later). The TR-004 is a nifty little device that allows for users to set a RAID mode for the 4-bay device with DIP switches on the unit, or through software on their Windows or MAC machines. It claims to have a USB 3.2 gen 1 over USB C port, and is designed as a standalone DAS either for added storage to a QNAP NAS, but also as a standalone DAS for a Windows, Mac, or Linux PC.
