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 transferts.

3.2 Initial RAID Configuration
The G-RAID Mirror ships pre-configured in RAID 1 (mise en miroir) 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. Utilisation de l'appareil
4.1 Transfert de données
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. Entretien
5.1 Entretien général
- Conservez l'appareil dans un environnement propre et sec, à l'abri de la lumière directe du soleil et des températures extrêmes.
- Assurez une ventilation adéquate autour de l’appareil pour éviter toute surchauffe.
- Nettoyez l'extérieur avec un chiffon doux et sec. Évitez d'utiliser des nettoyants liquides ou des solvants.
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. Dépannage
6.1 Appareil non reconnu
- Vérifiez que l'adaptateur secteur est correctement branché et que l'appareil est allumé.
- 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 Performances lentes
- 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.
- Vérifiez les processus en arrière-plan susceptibles de consommer des ressources système ou des E/S disque.
- Verify the RAID configuration. RAID 1 prioritizes data redundancy over maximum speed, while RAID 0 offers higher speeds.
