3.2 Installing 2.5-inch SATA HDDs/SSDs (Optional)
To install 2.5-inch SATA HDDs/SSDs, an optional 1125SS Mounting Bracket (not included) is required. Secure the 2.5-inch drive to the bracket, then mount the bracket into a 3.5-inch tray as described above. For a visual guide, refer to the official product video in the RAID Configuration section.
4. Connecting to Your Computer
- Connect the 12V/6.5A power adapter to the DC IN port on the back of the enclosure and then to a power outlet.
- Connect the USB Type-C data cable from the enclosure's Type-C port to an available USB port on your computer.
- Press the power button on the back of the enclosure to turn it on. The indicator lights on the front panel will illuminate.

5. RAID Configuration
The ORICO WS500RC3 supports multiple RAID modes to optimize performance or data redundancy. Warning: Changing RAID modes will erase all data on the installed hard drives. Back up your data before proceeding.
5.1 Available RAID Modes:
- RAID 0 (Striping): Combines drives for maximum speed and capacity. Offers no data redundancy.
- RAID 1 (Mirroring): Duplicates data across two drives for redundancy. Usable capacity is reduced by half.
- RAID 3 (Striping with dedicated parity): Data is striped across drives with one dedicated drive for parity. Offers good performance and redundancy.
- RAID 5 (Striping with distributed parity): Data is striped across drives with parity information distributed among them. Offers good performance and redundancy. Requires at least 3 drives.
- RAID 10 (Striping of Mirrors): Combines RAID 1 and RAID 0 for both performance and redundancy. Requires at least 4 drives.
- JBOD (Just a Bunch Of Disks): Drives are treated as individual, independent disks.
- CLONE: Creates an exact copy of one drive onto another.
- Normal: Each drive operates independently without RAID.
5.2 Setting RAID Mode
The RAID mode is configured using DIP switches located on the back of the enclosure. Refer to the diagram on the enclosure or in the full user manual for specific switch combinations for each RAID mode. After setting the switches, press and hold the "SET" button for 3-5 seconds until the indicator lights change, then release.
Video: This official ORICO video demonstrates the installation process, including how to set the RAID mode using the DIP switches on the back of the WS500RC3 enclosure.
6. Operating Instructions
6.1 Disk Management and Formatting
After connecting the enclosure and configuring RAID (if desired), the drives will appear in your operating system's disk management utility. You will need to initialize and format the drives before they can be used for storage.
- For Windows: Right-click "This PC" (or "My Computer") > "Manage" > "Disk Management".
- For macOS: Go to "Applications" > "Utilities" > "Disk Utility".
- Initialize the new disk(s) if prompted.
- Create new volumes (partitions) and format them with your preferred file system (e.g., NTFS for Windows, APFS/HFS+ for macOS).
Video: This official ORICO video demonstrates the process of initializing and formatting new volumes in Windows Disk Management for the WS500RC3.
6.2 Data Transfer
Once formatted, your new storage volume(s) will appear as regular drives in your operating system. You can drag and drop files, copy, paste, or use backup software to transfer data to and from the enclosure. The enclosure supports up to 5Gbps transfer speeds, ensuring efficient data handling.
6.3 Automatic Sleep Function
The enclosure features an automatic sleep function to conserve power and extend the lifespan of your hard drives. After approximately 30 minutes of inactivity, the installed drives will enter sleep mode. Any data access will automatically wake the drives.

7. Maintenance
- Ventilation: Always place the enclosure in a well-ventilated area to ensure proper airflow and optimal heat dissipation.
- Firmware Updates: Periodically check the official ORICO website for any available firmware updates for your device.
- Environmental Conditions: Avoid exposing the enclosure to extreme temperatures, high humidity, or direct sunlight.
- Cleaning: Clean the exterior of the enclosure with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Data Backup: Regularly back up your important data to another storage device, especially when using RAID modes that do not provide redundancy (e.g., RAID 0, JBOD).
8. Troubleshooting
8.1 Enclosure not recognized by computer:
- Ensure all cables (power and USB) are securely connected to both the enclosure and your computer.
- Verify that the power adapter is plugged into a working electrical outlet and the enclosure is powered on.
- Try connecting the enclosure to a different USB port on your computer or using a different USB cable.
- Check your computer's Device Manager (Windows) or System Information (macOS) to see if the USB device is detected.
- Confirm that the hard drives are properly installed and secured within their trays inside the enclosure.
8.2 Drives not appearing after connection:
- Access Disk Management (Windows) or Disk Utility (macOS) to check if the drives are detected but are uninitialized or unformatted. Follow the instructions in Section 6.1 to prepare the drives.
- If using RAID, ensure the RAID mode is correctly configured according to Section 5 and the drives are initialized and formatted.
- Test the hard drives individually in another enclosure or directly connected to a computer, if possible, to rule out individual drive failure.
8.3 Slow data transfer speeds:
- Ensure you are connecting the enclosure to a USB 3.0/3.1 compatible port on your computer using the provided USB 3.0 Type-C cable.
- Actual transfer speeds can be influenced by the performance of your installed hard drives and your computer's system resources.
- Verify that your computer's USB drivers are up to date.
8.4 Enclosure feels warm during operation:
- Ensure the enclosure is placed in a location with adequate ventilation and that the cooling fan is not obstructed.
- The aluminum alloy construction is designed to dissipate heat. Some warmth during continuous operation is normal and indicates effective heat transfer.
