QNAP TR-004U, RAID Expansion Enclosure, USB 3.0 and you can use it as DAS
RAID expansion box - USB 3.0 - Different RAID modes - 4 bays
The TR-004U is USB 3.0 RAID expansion enclosure allows you to expand the capacity of your QNAP NAS and PC. It can also be used as a DAS (Direct Attached Storage) device, giving you direct access to your content simply by connecting via USB. In addition, it has four 3.5-inch SATA drive bays with multiple RAID configuration options and USB 3.0 Type-C connectivity that will provide you with a highly reliable and secure storage capacity expansion solution.
Supports multiple RAID levels
The TR-004U supports various RAID configurations. Depending on your requirements, you can switch between hardware-controlled or software-controlled RAID modes. Move the DIP switches to the corresponding positions for your ideal RAID mode: Single, JBOD, RAID 0, RAID 1/10, or RAID 5. You can also perform RAID configuration from your QNAP NAS, or by using the QNAP External RAID Manager utility on the computer. Modes like:
- Single mode: Treats each disk as a separate storage space, allowing each to be accessed independently.
- JBOD mode: All disks are recognized as a single drive. This allows you to use the storage to its fullest, but does not provide any protection for your data.
- RAID 0 mode: Data is striped across the drives. RAID 0 provides faster performance, but does not protect data in case of 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 expense of only being able to use half of the installed storage space.
- RAID 5 mode: RAID 5 requires the use of at least three drives; parity information is distributed across drives, providing optimized storage capacity and protection in the event of a drive failure.
- Software Control Mode: Use this mode to control the RAID configuration from your NAS or computer.
