2.2 Installing 2.5"/3.5" SATA HDDs/SSDs
- Gently remove the top magnetic cover of the enclosure.
- Pull out the drive trays from the front bays.
- For 3.5" HDDs: Snap the drive into the tray using the side pins. No screws are typically needed for tool-free installation.
- For 2.5" SSDs/HDDs: Secure the drive to the tray using the provided screws through the bottom mounting holes.
- Slide the loaded drive tray back into the enclosure until it clicks securely into place.
- Repeat for the second drive if applicable.

2.3 Installing M.2 NVMe SSD
- Locate the NVMe SSD slot on the side of the enclosure and open its magnetic cover.
- Insert the M.2 NVMe SSD into the slot at an angle.
- Gently press down the SSD and secure it with the provided rubber plug or screw, depending on the design.
- Apply the thermal pad and heatsink (if provided) to the M.2 SSD for optimal heat dissipation.
- Close the magnetic cover.

2.4 Connecting to Host Device
- Connect the provided DC 12V5A power adapter to the enclosure's DC IN port and plug it into a power outlet.
- Use the supplied USB-C to USB-C cable to connect the enclosure's "PC IN" port to your Mac mini, PC, or laptop.
- Power on the enclosure using the ON/OFF switch.
- Your operating system should detect the new storage devices. You may need to initialize and format the drives before use (refer to your OS documentation).

3. Operating Instructions
3.1 RAID Configuration
The HSD10-US supports multiple RAID modes for the two SATA drives. The RAID mode is selected using the physical DIP switches located on the rear of the unit. Important Note: The physical RAID mode selector switches on this unit operate in a reverse order (from bottom to top). Users must verify the selected mode against the indicator panel prior to finalizing the configuration to ensure data integrity and prevent unintended data loss.
| RAID Mode | Description | Switch Setting (Bottom to Top) |
|---|---|---|
| PM (Port Multiplier) | Each drive appears as an independent disk. | UP-UP |
| RAID 0 (Striping) | Combines drives for maximum performance and capacity, but offers no data redundancy. | UP-DOWN |
| RAID 1 (Mirroring) | Mirrors data across both drives for data redundancy. Capacity is limited to the smallest drive. | DOWN-UP |
| JBOD (Just a Bunch Of Disks) | Combines drives into a single large volume without performance or redundancy benefits. | DOWN-DOWN |
After setting the DIP switches, press and hold the "SET" button for 5 seconds while the power is on to apply the new RAID configuration. All data on the drives will be erased during RAID configuration. Back up important data before proceeding.

3.2 Data Transfer and Connectivity
The enclosure supports high-speed data transfer up to 10Gbps via its USB 3.2 Gen 2 interface. Utilize the front-facing USB-A (10Gbps) port for fast peripheral connections, and the three USB 2.0 ports for standard peripherals like keyboards and mice. The integrated SD/TF card readers allow for convenient data import from memory cards.

4. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the enclosure. Avoid liquid cleaners or abrasive materials.
- Ventilation: Ensure that the ventilation ports on the top and bottom panels are not obstructed to maintain optimal airflow and prevent overheating.
- Drive Health: Regularly check the health of your installed drives using your operating system's disk utility tools.
- Firmware Updates: Check the Yottamaster official website periodically for any firmware updates for your HSD10-US model.

5. Troubleshooting
- Drives Not Detected:
- Ensure the power adapter is securely connected and the enclosure is powered on.
- Verify the USB-C cable is correctly connected to both the enclosure and the host device.
- Check if the drives are properly seated in their trays/slots.
- For new drives, ensure they are initialized and formatted by your operating system.
- If using RAID, confirm the DIP switches are set correctly and the configuration has been applied by pressing the SET button.
- Slow Data Transfer Speeds:
- Ensure your host device's USB port supports USB 3.2 Gen 2 (10Gbps) for optimal performance.
- Verify the USB-C cable used is rated for 10Gbps data transfer.
- Performance can be limited by the speed of the slowest drive in a RAID 0 or JBOD setup.
- Enclosure Overheating:
- Ensure adequate ventilation around the enclosure. Do not block air vents.
- Confirm the internal cooling fan is operating.
