4-bay USB 3.0 RAID Expansion Enclosure

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.

  • USB 3.0 Type-C port for faster data transfer.
  • Supports up to four SATA drives for reliable read and write performance
  • Disk mode DIP switch to change from Hardware Control and Software Control configurations for setting RAID group.
  • Lockable hard drive trays to prevent accidental drive removal.
  • Eject button for disconnecting the TR-004 from a NAS or computer (Requires the QNAP External RAID Manager utility)
  • Instantly back up files from the TR-004 to the NAS using the One Touch Copy button (Requires a QNAP NAS with a one touch copy button and QTS 4.3.6 (or later) when in external drive mode.)

Effective storage expansion with RAID Support
The TR-004 is an ideal storage expansion solution for PCs, especially for laptops which lack the ability to install larger, higher-capacity drives. Featuring four 3.5-inch SATA drive bays and supporting RAID configuration, the TR-004 provides the ability to store a vast number of files and data and to ensure protection against potential drive failure.

Supports various RAID levels
The TR-004 supports a variety of RAID configurations. Depending on your requirements, you can switch between hardware- or software-controlled RAID modes. Move the DIP switches to corresponding positions for your ideal RAID mode: Individual, JBOD, RAID 0, RAID 1/10 or RAID 5. You can also configure the RAID settings from your QNAP NAS, or by using the QNAP External RAID Manager utility on your computer.

Individual Mode
Treats every disk as separate storage space, allowing you to independently access each one.

JBOD Mode
All the disks are recognized as a single drive. This allows maximal storage utilization but provides no data protection.

RAID 0 Mode
Data is split amongst the drives. RAID 0 provides the fastest performance but does not protect data from drive failure.

RAID 1/10 Mode
Half of the total storage capacity is used to store data, and the other half keeps a copy of this data. This provides high data protection at the cost of only being able to use half the installed storage space.

RAID 5 Mode
RAID 5 requires at least three drives to use and parity information is distributed among the drives, providing optimized storage capacity and protection against one disk failing.

Software Ctrl Mode
Use this mode to control the RAID configuration from your NAS or computer.
