The Gemini Thunderbolt 3 Dock and Dual-Drive RAID Enclosure from OWC / Other World Computing will help you organize your digital life. With dual drive bays and multiple connectivity options, you’ll have plenty of room to duplicate footage, create and manage archives, or render and process effects.
OWC built this dock with two SATA III drive bays that can accommodate 3.5″ hard drives, as well as 2.5″ hard drives and SSDs. Compatible with macOS 10.14, 10.15, and 11.x, plus Windows 10 and Windows Server 2016, connectivity options include two 40 Gb/s Thunderbolt 3 ports, each of which deliver up to 27W (9V / 3A) of power, two 5 Gb/s USB 3.2 Gen 1 Type-A ports, one DisplayPort, one Gigabit Ethernet port, and one UHS-II SD card reader. While one of the Thunderbolt 3 ports is used to interface with your host system, the other can be used to connect additional peripherals.
The Gemini also supports hardware RAID configurations of RAID 0, which provides performance but no data redundancy, and RAID 1, which provides data redundancy at the cost of performance. For those who do not require a RAID, JBOD and SPAN are available. JBOD lets each drive be used independently, while SPAN combines each individual drive into one large volume.
Please note that this device must be connected to your host system using Thunderbolt 3 and cannot be used as a NAS. The Ethernet port provides the computer with a network connection over Thunderbolt 3, but cannot be used to access data on the drives over the network.
You can customize the Gemini to quickly adapt to project changes and help you stay ahead of deadlines. Install your choice of 2.5″ or 3.5″ HDDs or SSDs, and even combine the speed of a SSD and with the cost-effective storage capacity of a HDD. With a built-in hardware RAID, you have four drive set-up choices:
- Non-RAID (JBOD) 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
