Description
The TR-004U USB 3.2 Gen 1 RAID expansion enclosure allows you to expand the storage capacity of your PC and QNAP NAS. The TR-004U can also be used as a Direct-Attached Storage (DAS) device, giving you direct access to its contents by connecting it via USB. The TR-004U offers four 3.5-inch SATA drive bays with multiple RAID configuration options and USB 3.2 Gen 1 Type-C connectivity, making it a highly reliable and secure storage expansion solution.
Supports different RAID levels
The TR-004U supports various RAID configurations. Depending on your needs, you can switch between Hardware Controlled or Software Controlled RAID modes. Move the DIP switches to the corresponding positions for your ideal RAID mode: Individual, JBOD, RAID 0, RAID 1/10, or RAID 5. You can also configure RAID settings from your QNAP NAS or using the external QNAP RAID Manager utility on your computer.
Individual mode
Treats each disk as a separate storage space, allowing you to access them independently.
JBOD mode
All disks are recognized as a single drive. This allows for maximum storage utilization but offers no data protection.
RAID 0 mode
The data is distributed across the disks. RAID 0 offers the fastest performance but does not protect data against disk failures.
RAID mode 1/10
Half of the total storage capacity is used to store data, and the other half keeps a copy of that data. This provides a high level of data protection at the cost of only being able to use half of the installed storage space.
RAID 5 mode
RAID 5 requires at least three disks to be used and parity information is distributed between the disks, providing optimized storage capacity and protection against disk failures.
Software Control Mode
Use this mode to control the RAID configuration from your NAS or computer.
Flexible storage configuration and management
Compared to other RAID enclosures, the TR-004U offers software-controlled configurations for greater management flexibility. Users can configure RAID and monitor disk health using the Storage & Snapshots Manager on a QNAP NAS, or using QNAP's external RAID Manager utility on their computer.
Versatile use cases to meet storage expansion needs
The TR-004U meets many storage expansion requirements for personal and professional use, including:
Scenario 1: Increase the capacity of your NAS
The TR-004U provides users with an alternative method to expand the storage capacity of their rack-mounted NAS. By connecting the TR-004U to their NAS and using the Storage & Snapshots Manager, users can easily configure and manage their storage expansion. The TR-004U supports various QNAP NAS storage and file management features, allowing users to create storage pools, search for files with Qsirch, and organize files with Qfiling.
Use the TR-004U as an alternative to traditional NAS expansion enclosures
As an external hardware RAID device, the TR-004U operates independently and does not require additional system resources from the NAS. Compared to the UX-500P expansion enclosure, the TR-004U uses fewer NAS system resources.
Scenario 2: External storage for your NAS
Instead of using the TR-004U to expand the capacity of your QNAP NAS, you can use it as additional storage for data backup or migration. It also allows you to physically migrate massive amounts of data that require significant network bandwidth. When connected to the NAS, you can monitor the health and status of the TR-004U using the Storage & Snapshots Manager on the NAS.
Scenario 3: Increase the storage space on your computer and server
The TR-004U can quickly add storage space to your computer and server. You can use the DIP switch to configure a hardware RAID mode or manage it using the QNAP External RAID Manager utility. The health and status of the TR-004U can also be monitored using the QNAP External RAID Manager utility.
QNAP External RAID Manager requires Windows 7 (or later), Windows Server 2012 R2 (or later) and macOS 10.13 (or later).
Scenario 4: Cross-platform file sharing
From your NAS to Windows, Mac, and Linux computers, the TR-004U is compatible with a wide range of devices. This makes it ideal for quickly moving large files between different devices. The TR-004U is even compatible with devices that use the exFAT* file system, making it even more convenient for accessing and sharing files from multiple devices.
* To access devices that use the exFAT file system, users must purchase a separate exFAT driver license.
