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 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 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. 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.

QuTS hero คือระบบปฏิบัติการสำหรับรุ่นของ QNAP NAS ระดับสูงและระดับองค์กร ระบบ Linux และ ZFS ทำให้ QuTS hero สามารถรองรับเทคโนโลยีการลดปริมาณข้อมูล เพื่อลดค่าใช้จ่ายและเพิ่มความเชื่อถือได้ของที่เก็บข้อมูลชนิด SSD (All Flash) ระบบ 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. 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. Hi all! I have a QNAP TS-332X with a TR-004 attached to it. QTS is 4.3.6.0895. The firmware ver on the TR-004 is 1.0.4. Inside I have white label Western Digital WD80EMAZ 256MB Cache - pulled from WD 8TB Elements Desktop Hard Drives WDBWLG0080HBK-NESN. Using TR-004 to manage drives, not software management, via dip switches.

QNAP TR-004 4 Bay USB 3.0 RAID NAS Expansion Enclosure

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 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 Individual, JBOD, hardware RAID 0/1/5/10, Software CTRL (Software control mode is for use with QNAP NAS and Windows/macOS utility) 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).

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: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 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. Warning: Using unsupported modules may degrade performance, cause errors, or prevent the operating system from starting.

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.

Product Reviews

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.

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.

From the Manufacturer

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.
