Hardware RAID to protect you against drive failure
You can customize the Gemini to quickly adapt to project changes and help you stay ahead of deadlines. Install your choice of 2.5-inch or 3.5-inch HDDs or SSDs and even combine the speed of a SSD with the cost-effective storage capacity of a HDD. With built-in hardware RAID, you have four drive set-up choices:
- Non-RAID to keep the drives as independent volumes
- RAID 1 (mirror) for backup reliability
- RAID 0 (stripe) for optimal performance and maximum speed or use
- Span to combine the drive capacities into one huge volume for extra-large storage capacities
Done with the drives but need the connectivity? Use OWC's free utility to quickly and safely eject the RAID or any other disks attached to the Gemini.

- Thunderbolt 2/Thunderbolt compatibility requires a certified and a Thunderbolt 2 cable (available separately). This configuration provides data transfer at up to 20Gb/s but does not support notebook charging.
- Must be connected to host computer via Thunderbolt (USB-C), and cannot be used as a NAS. The Ethernet port provides the host computer with a 2.5GbE network connection over Thunderbolt (USB-C), but it cannot be used to access the drives over the network.
- Requires 2.5Gb/s Ethernet compatible hardware components and cabling (Cat 5e cable minimum, Cat 6 or later strongly recommended).
- OWC ShuttleOne 1 x NVMe M.2 and U2 Shuttle 4 x NVMe M.2 to 2.5-inch U.2 SSD Adapters sold separately.
