Boost the storage capacity of your laptop with the 8TB Gemini Thunderbolt 3 Dock and RAID Station from OWC. Equipped with a pair of 4TB hard drives, the Gemini comes with two Thunderbolt 3 ports, ideal for connecting to your computers as well as daisy chaining up to five Thunderbolt 3 devices. The storage system also features two USB 3.0/3.1 Gen 1 Type-A ports, a Gigabit Ethernet port, a DisplayPort, and an SD card reader. With its hardware RAID controller, the Gemini Thunderbolt 3 RAID Station supports RAID modes 0 and 1, as well as SPAN and JBOD modes. A fan ensures components stay cool.

Hardware RAID Controller

With the built-in hardware RAID controller, you can mirror the drives with RAID 1 as a reliable backup for your important data, you can stripe the drives with RAID 0 for optimal performance and maximum speed, or you can select SPAN to combine the drives for extra-large storage capacities.

OS Independent RAID Set

An advantage of the built-in hardware RAID controller is that the RAID set is OS-independent, meaning the storage drive can be moved from one system to another with ease. Because the RAID set is managed inside the Gemini, no additional setup is required on your computer.

2-Lane PCIe to SATA Controller

The PCIe-to-SATA controller makes use of two PCIe lanes. When using a non-RAID configuration, this allows for a single SSD to run at full SATA 6Gb/s speeds and deliver read transfer rates over 500 MB/s.

Power Delivery

The Gemini Thunderbolt 3 Dock and RAID Station supports USB Power Delivery (PD), providing 27W of power to laptops that support charging from a 9V/3A power source, such as the late-2016 MacBook Pro. This allows you to recharge your laptop battery even when it is not plugged into any other power source.

Tool-Less Drive Installation

For added convenience and flexibility, the Gemini can accommodate both 2.5 and 3.5" SATA drives. The assembly is completely toolless so drives can be easily installed or uninstalled.

LED Indicators

The LED lights on the front indicate the power status and disk activity while the LED lights on the back show the network speed and status when an Ethernet cable is connected.
