How to install OWC 4TB Gemini Thunderbolt Dock And Dual-Drive HDD RAID External Storage Solution

• Power down your computer and the Gemini enclosure before installation to ensure safe hardware handling.
• Open the drive bays using the indicated tool-less trays and insert two 3.5" SATA HDDs. Confirm the drives are seated firmly in their slots for reliable connections.
• Connect the drives to the Gemini RAID enclosure using the provided cables and secure the trays so that the drives are held in place during operation.
• Attach the external power supply to the Gemini enclosure and plug it into a reliable power outlet to ensure stable performance during high-demand transfers and RAID rebuilds.
• Connect the Gemini unit to your computer with the included Thunderbolt 3/4 cable. If your setup also uses USB-C peripherals, connect compatible devices to the dock’s USB-C ports as needed and verify host detection in your operating system.
• Power on the enclosure and configure the desired RAID mode using the onboard controls or the recommended software utility from OWC, selecting RAID 0 for speed or RAID 1 for redundancy as your workload requires.
• Upon first connection, format the new RAID volume in your operating system (APFS or Mac OS Extended on macOS; NTFS or exFAT on Windows, depending on cross-platform needs). Give the volume a clear, searchable name to optimize searchability in your library.
• Test read/write performance with a representative file set to confirm that the throughput and stability meet your workflow expectations, and then begin moving your project files, media libraries, or backups to the Gemini array.
