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.

Up to 1446MB/s Real-World Performance

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.
