Stay Connected to Your Team and Media
The OWC Gemini features a 2.5Gb/s Ethernet port so you can transfer files and work up to 2.5x faster over wired networks and enjoy increased productivity in an IP-based workflow. Great for shared workspaces and workflows, file transfers breeze by quickly so you spend less time setting up and more time getting to work. It’s also great for sending your files over to a NAS to keep them safely archived. When it’s time to share your progress, you can use your RAID options to render out working files and a fast connection to post for team and client reviews.
Gain an 8K Perspective
With a dedicated latest generation HDMI port, Gemini empowers you to add the fresh, crisp perspective of an 8K display to your workflow.

OWC Gemini fights the clutter with a single-cable connection that delivers storage, ethernet sharing, charging power, and 8K monitor support while neatly consolidating all your peripheral device cables. Reclaim your workspace and reduce your stress.
Finally, a RAID as Mobile as Your Life
If you work in a cross-platform world, you can easily connect OWC Gemini to Mac and PC using OWC's MacDrive software (sold separately).
