SanDisk Professional 24TB G-RAID Mirror External Hard Drive Instruction Manual

1. Introduction

The SanDisk Professional G-RAID Mirror is a high-performance external hard drive system designed for professionals requiring reliable data storage with redundancy. This device features two 7200RPM Ultrastar Enterprise-class Hard Drives, configured in RAID 1 (Mirroring) by default, ensuring automatic duplication of your valuable content for enhanced data protection. It offers high-speed connectivity through Thunderbolt 3 and USB (10Gbps) interfaces, making it suitable for demanding workflows such as video editing and large file transfers.

3.2 Initial RAID Configuration

The G-RAID Mirror ships pre-configured in RAID 1 (Mirroring) mode. This configuration provides data redundancy by duplicating all data across both internal drives, ensuring that if one drive fails, your data remains accessible on the other. The usable capacity in RAID 1 is half of the total raw capacity (e.g., 24TB total raw capacity provides 12TB usable capacity in RAID 1).

3.3 PRO-BLADE SSD Mag Slot

The device includes a PRO-BLADE SSD Mag slot, allowing you to easily integrate a PRO-BLADE SSD Mag (sold separately) for additional high-speed storage. This feature simplifies and speeds up transfers, editing, and backup processes without requiring extra workspace.

4. Operating the Device

4.1 Data Transfer

Once connected and recognized by your operating system, the G-RAID Mirror functions like any other external drive. You can drag and drop files, use backup software, or integrate it into your creative applications for direct access to your stored content.

4.2 Changing RAID Settings

The G-RAID Mirror features a hardware RAID selector on the back of the unit. While it ships in RAID 1, you can change the configuration to RAID 0 for increased speed (up to 480MB/s read) or other modes as supported by the device. Refer to the detailed user manual for specific instructions on how to safely change RAID configurations, as this process typically involves reformatting the drives and will erase all data.

5. Maintenance

5.1 General Care

• Keep the device in a clean, dry environment, away from direct sunlight and extreme temperatures.
• Ensure proper ventilation around the unit to prevent overheating.
• Clean the exterior with a soft, dry cloth. Avoid using liquid cleaners or solvents.

5.2 Drive Health

Regularly check the health of your drives using your operating system's disk utility tools or any provided SanDisk Professional software. While RAID 1 offers redundancy, it is not a substitute for a comprehensive backup strategy.

6. Troubleshooting

6.1 Device Not Recognized

• Ensure the power adapter is securely connected and the device is powered on.
• Verify that the Thunderbolt or USB cable is correctly connected to both the device and your computer. Try a different port or cable if available.
• Restart your computer and the G-RAID Mirror.
• Check your computer's Disk Management (Windows) or Disk Utility (macOS) to see if the drive is detected but not mounted or formatted.

6.2 Slow Performance

• Ensure you are using a Thunderbolt 3 or USB (10Gbps) port on your computer for optimal speeds. Older USB ports will result in slower performance.
• Check for background processes that might be consuming system resources or disk I/O.
• Verify the RAID configuration. RAID 1 prioritizes data redundancy over maximum speed, while RAID 0 offers higher speeds.
