4. Operating
4.1 RAID Mode Configuration
The ORICO 9848RU3 supports various RAID modes to meet different data storage needs. These modes include RAID 0, RAID 1, RAID 3, RAID 5, RAID 10, JBOD, CLONE, and Normal. Refer to the table below for a summary of each mode's characteristics.

Figure 5: A table detailing the 8 supported RAID modes, including minimum number of disks, capacity utilization, and safety levels.
Detailed instructions for configuring RAID modes are typically found in a separate advanced user guide or through the device's management software. Please consult the ORICO website or support for specific RAID setup procedures.
- RAID 0: Data striping for maximum performance and capacity, no redundancy.
- RAID 1: Data mirroring for redundancy, half capacity, good for critical data.
- RAID 3: Striping with dedicated parity, good for large sequential reads.
- RAID 5: Striping with distributed parity, good balance of performance, capacity, and redundancy.
- RAID 10: Striping and mirroring, high performance and redundancy, requires at least 4 drives.
- JBOD (Just a Bunch Of Disks): Combines disks into a single large volume without striping or mirroring.
- CLONE: Creates an exact copy of one disk onto another.
- Normal: Each disk operates independently.
4.2 Data Transfer
The enclosure utilizes a USB 3.0 interface, allowing for high-speed data transfer rates of up to 230 MB/s, ideal for large files and backups.
