2. Configuração RAID
The OWC Gemini supports hardware RAID. Refer to the specific RAID configuration utility or physical switches on the device (if present) to set your desired RAID level (RAID 0, RAID 1, SPAN, or JBOD).

RAID Levels Explained:
- RAID 0 (Striping): Combines drives for maximum speed and capacity, but offers no data redundancy.
- RAID 1 (espelhamento): Duplicates data across drives for redundancy, sacrificing half the total capacity for data protection.
- SPAN (Concatenação): Combines drives into a single large volume without striping or mirroring.
- JBOD (Just a Bunch Of Disks): Treats each drive as an independent volume.
3. Conectando ao seu computador
- Connect the power adapter to the DC 12V power input on the OWC Gemini and then to a power outlet.
- Connect one end of the Thunderbolt (USB-C) cable to the host port on the OWC Gemini.
- Connect the other end of the Thunderbolt (USB-C) cable to a Thunderbolt (USB-C) port on your computer.
- The device should power on automatically.
4. Initializing Drives
After connecting, your operating system may prompt you to initialize and format the new drives. Follow the on-screen instructions. For macOS, use Disk Utility. For Windows, use Disk Management.
