Effective storage expansion with RAID Support

The QNAP 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.
