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

Product Information

Warning: Using unsupported modules may degrade performance, cause errors, or prevent the operating system from starting. 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: Drives can only be migrated from one TR-004 to another TR-004. The files and data stored on drives moved to/from a NAS (or another device) will not be recognized. There are three drives in the TS-332X in RAID-5 but writes to those work great - ~300MB/s from PC to NAS. It seems only the TR-004 is affected.

Without going too much into the software, it has some good basic functionality. It allows offers RAID setup, individual drive information including S.M.A.R.T. values direct from the drives, which you can't do with other utilities in Windows or on MacOS when connected to the TR-004. Simple status for each drive is also displayed like "GOOD" and associated drive bay also highlighted green if there's no issues. Firmware can also be updated through this app as well. So far mine came with the latest 1.004. Me too got the TR-004 with 4 x Ironwolf Pro (4TB) disks in a Raid 5 config (and the TVS-872xt) over 10gb Ethernet connection to my M1 MBP with pretty much the same speeds that you present here!

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. 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?

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. QuTS hero is the operating system for high-end and enterprise QNAP NAS models. With Linux and ZFS, QuTS hero supports advanced data reduction technologies for further driving down costs and increasing reliablility of SSD (all-flash) storage. System 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. 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.spindown is good for saving on electricity bill, and MAY prolong life. I say MAY, because if you are spinning up the drives too often, it MAY instead be negatively affecting longevity i suspect. If you won't be triggering much spin up/downs on a highly frequent basis, it may be worth doing. 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 connected to a Windows 10 and configured in RAID 5 (formatted as HFS): read/write at 190MB/s - 200MB/s QTS คือระบบปฏิบัติการสำหรับ QNAP NAS ระดับเริ่มต้นและระดับกลาง ระบบ Linux และ ext4 ทำให้ QTS เป็นที่เก็บข้อมูลที่เชื่อถือได้สำหรับทุกคน ด้วยฟีเจอร์และแอปต่างๆ ที่เพิ่มมูลค่าและมีประโยชน์หลากหลาย อย่างเช่น สแนปช็อต, Plex Media Server และระบบคลาวด์ส่วนตัวของคุณที่เข้าถึงได้ง่าย ระบบ

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). 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. Disk mode DIP switch to change from Hardware Control and Software Control configurations for setting RAID group.Individual, JBOD, hardware RAID 0/1/5/10, Software CTRL (Software control mode is for use with QNAP NAS and Windows/macOS utility) QuTS hero คือระบบปฏิบัติการสำหรับรุ่นของ QNAP NAS ระดับสูงและระดับองค์กร ระบบ Linux และ ZFS ทำให้ QuTS hero สามารถรองรับเทคโนโลยีการลดปริมาณข้อมูล เพื่อลดค่าใช้จ่ายและเพิ่มความเชื่อถือได้ของที่เก็บข้อมูลชนิด SSD (All Flash) ระบบ 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). I then pulled a drive from the array, and got three very loud beeps and the status light blinking red. 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.

anyway if you are interested on the topic, you can google "spindown vs 24/7 hard drive", there should be an answer on reddit or on quora on the subject. There are 2 camps, those for spindown, and those for keeping the disks on nas running 24/7.

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 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). 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. The storage pools and volumes in the expansion enclosures are configured via the QTS operating system.
