Overview
Ultra-Performance and Convenience for Production Workflows
While our base model Gemini is great for everyday content creators, you are worlds beyond ordinary. Your workflow is at the extreme edge of resolutions, codecs, and framerates. We understand your need to push into an ‘other world’ of capability, and pros like you are the reason we created the Gemini Ultra.
Powered by up to six NVMe SSDs, you’ll have the horsepower to handle the most demanding photography, video, and editing tasks you face. Edit ultra-high resolution files on the fly, ingest several media cards in parallel and render dailies without a hitch, and rip through 8K footage with up to 2381MB/s real world speed.1
Beyond performance, with Gemini Ultra’s seven connectivity ports, you will experience an incredible level of versatility. Use your favorite accessories and charge small mobile devices via two USB ports. Daisy chains up to five Thunderbolt devices so that you can create additional backups. Offload media cards faster and easier with the frontside UHS-II slot or external card readers via Thunderbolt or USB-C. Transfer files and work up to 2.5x faster over wired networks and enjoy increased productivity when working with NAS devices with 2.5Gb/s Ethernet. Add an external monitor with up to 8K resolution via HDMI.

Your Choice of Ultra Speed or Protection
Gemini Ultra’s two models let you decide what’s most important in your workflow: maximum performance or the optimal balance of speed and data protection.
Put Ultra X2 to Work
Make your dream of becoming an editing powerhouse a reality by utilizing the performance of NVMe SSDs. With dual drives preset in SoftRAID RAID 0, you’ll have 1446MB/s3 of bandwidth to handle demanding media workflows such as 8K video and 6K multicam sequences using advanced 10 bit and 12 bit codecs, high framerate footage, and ultra-high resolution RAW pictures. Plus, you’ll have all the advanced drive health monitoring benefits of SoftRAID so you can work worry-free. You can also use SoftRAID to change to RAID 1 data protection with speeds up to 721MB/s.
Ultra X2 Models
Pro photographers and photography studios on tight deadlines can batch edit and export thousands of 60 Megapixel RAW pictures at blazingly fast speeds.
Documentary filmmakers can easily ingest media and cut through hours of 4K footage at up to 1446MB/s using RAID 0 with this all-in-one solution to keep all the files in one place.
Professionals working in a studio with NAS devices can benefit from the faster speeds of the built-in storage as an active drive and backup their files back to the NAS at up to 2.5Gb/s when projects are completed.
Put Ultra X6 to Work
Level up to the ultimate production grade workflow storage and docking convenience solution on the market. This dual drive model adds higher capacity and RAID configuration possibilities – like RAID 0 for speed or RAID 5 for data protection – to empower you with advanced performance. And SoftRAID is there helping you manage it all easily.
Ultra X6 Models
Production companies and video editors can easily backup and edit hours of 8K RAW video with advanced codecs (ProRes RAW, R3D, Blackmagic RAW) at up to 2381MB/s using RAID 0.
DITs working for Netflix can offload and backup camera files at 1761MB/s using RAID 5 data protection technology.
VFX compositors and artist can benefit from the insane speeds of the NVMe RAID when using EXR files or 3D simulations while streamlining NAS-based workflows with Gemini’s 2.5GbE connection.

This ensures your Gemini Ultra arrives operating properly and immediately ready for demanding use.
From the Rocket Yard Blog
OWC Gemini Makes 3-2-1 Video Archival Easy. Here’s How to Protect Your Files
Pro video teams should always back up at least three copies of their videos in two locations. OWC Gemini makes the process easy. Here are our tips for archival strategy with this all-in-one wonder.
Thunderbolt Made Easy
We make it easy to choose the right gear. Our Thunderbolt Certified products offer the same performance and functionality whether they are Thunderbolt 3 or Thunderbolt 4. And if you’re rocking a beloved Thunderbolt 2 machine, we offer a certified Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter so you can plug into our universe of award-winning solutions. No hassles, no confusion. That’s the OWC Difference.
Apple Mac models with Thunderbolt 2/Thunderbolt ports can be connected using a certified Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt 2 cable (not included). This configuration provides data transfer at up to 20Gb/s but does not support notebook charging.
Disconnect in One Click
Safely disconnect multiple drives in a single click. OWC Dock Ejector was designed by OWC hardware and software engineers to ensure all data is written before disconnection, saving time and protecting against data loss. It makes losing your hard-earned work a thing of the past.
Work with Ultimate Confidence
Active workspaces expose gear to unexpected bumps and shoves. OWC ClingOn custom cable stabilizers (sold separately) screw into the OWC Dock or OWC Drive housing to reduce – if not completely eliminate – cable strain on Thunderbolt and USB-C connections so you can work with ultimate confidence even in the highest foot traffic environments.
OWC Thunderbolt Cable Included
OWC Gemini comes with a certified 0.7M OWC Thunderbolt Cable. But if your workflow demands a different length to make the connection, OWC Thunderbolt (USB-C) Cables are the perfect choice.
