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

Product Information

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: QTS is the operating system for entry- and mid-level QNAP NAS. WIth Linux and ext4, QTS enables reliable storage for everyone with versatile value-added features and apps, such as snapshots, Plex media servers, and easy access of your personal cloud. System QuTS hero คือระบบปฏิบัติการสำหรับรุ่นของ QNAP NAS ระดับสูงและระดับองค์กร ระบบ Linux และ ZFS ทำให้ QuTS hero สามารถรองรับเทคโนโลยีการลดปริมาณข้อมูล เพื่อลดค่าใช้จ่ายและเพิ่มความเชื่อถือได้ของที่เก็บข้อมูลชนิด SSD (All Flash) ระบบ the tr-004 uses usb to connect to the qnap, so you need to disengage by using the eject, waiting for it to inform you it's safe, before you can shutdown the tr-004 device. 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.

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.

From the Manufacturer

in regards to spindown, afaik, if you power off the nas, this would automatically put the connected tr-004 into a spindown state if i read this correctly. this feature was mentioned on reddit if not mistaken. 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 storage pools and volumes in the expansion enclosures are configured via the QTS operating system. 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 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.

I then pulled a drive from the array, and got three very loud beeps and the status light blinking red. 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. Key Features 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. Note that I get read speeds ~150MB/s still under this configuration. A couple interesting tidbits. First, when I connect the unit directly to a Windows PC, I am able to write at ~100MB/s! What's very interesting is that at first, I would get slow write speeds ~40MB/s on the Windows PC. I enabled write caching in Windows for the device (I guess it defaulted off because it's external storage) and then I got the 100MB/s speeds I quoted above. It's like write cache is disabled on the NAS - however, I verified that in Control Panel -> System -> Hardware -> General tab, Enable Write Cache (EXT4 delay allocation) is enabled. I've also tried with and without Control Panel -> Network & File Services -> Win/Mac/NFS -> Microsoft Networking -> Advanced Options -> Enable Asynchronous I/O enabled. I also tried disabling the "Enable Write Cache." It seems like the combination that gives the best performance for the internal RAID is for Enable Write Cache to be enabled and Enable Asynchronous I/O to be disabled (which I believe is default config out of the box). Warning: Using unsupported modules may degrade performance, cause errors, or prevent the operating system from starting.

Product Reviews

Perhaps the Enable Write Cache setting only controls write cache for internal drives and not external? Was on the phone with QNAP support for 45 minutes. Tried various things. Time ran out for the day, so got off the phone and continued to troubleshoot. Here's one we both couldn't figure out: in Storage and Snapshots > External Storage, the "Type" for the tr-004 was showing up as USB 2.0, even though it was connected via USB-C on the tr-004 to USB-C on the TVS-872ZXT.

The TR-004 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-004. QTS คือระบบปฏิบัติการสำหรับ QNAP NAS ระดับเริ่มต้นและระดับกลาง ระบบ Linux และ ext4 ทำให้ QTS เป็นที่เก็บข้อมูลที่เชื่อถือได้สำหรับทุกคน ด้วยฟีเจอร์และแอปต่างๆ ที่เพิ่มมูลค่าและมีประโยชน์หลากหลาย อย่างเช่น สแนปช็อต, Plex Media Server และระบบคลาวด์ส่วนตัวของคุณที่เข้าถึงได้ง่าย ระบบ how r u configuring it to begin with ? since you plug direct into the 431, can i assume you are managing it via qts and not independently using the tr-004 windows management app? 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.

I had this same issue (30MB/s read and write speeds) and resolved it by uninstalling the USB drivers, rebooting my Win 10 PC, and allowing the system to reinstall the drivers. Now data transfers are around 200MB/s. I really don't think it has anything to do with supposed poor performance by the TR-004. The box works just fine, as advertised. Sometimes USB drivers need to be reinstalled and reinitialized, particularly when different devices (such as USB Headphones or a USB Mouse) are exchanged for another device (such as a mass storage device). When connected to a Windows 10 and configured in RAID 5 (formatted as HFS): read/write at 190MB/s - 200MB/s 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. 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. The TR-004U 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).
