The Do-It-All Tool for Digital Workflows
With dual drive bays and seven connectivity ports including an SD 4.0 card reader, the OWC Gemini is the do-it-all tool that will organize your digital life. You'll have plenty of room to duplicate footage, create and manage archives, or render and process effects. Connect your favorite peripherals via USB ports. Ingest the day's shoot or drone footage with the frontside reader.
Hardware RAID: Speed, Reliability, Flexibility
The OWC Gemini utilizes hardware RAID to unleash the full potential of two 3.5" 7200RPM hard drives. Preconfigured in high-speed RAID 0 mode to deliver maximum throughput from its drives, the Mercury Gemini offers real-world speeds up to 773MB/s to handle HD video workflows. If you desire the extra security of mirrored data, you can configure the Mercury Gemini in RAID 1 mode. Need more drive flexibility? Set up a span to combine the capacity of the two drives into one huge volume or use the drives as independent volumes.
Stay Connected to Your Team and Media
The OWC Gemini features a powerful Gigabit Ethernet port that keeps you connected at top speeds. Great for shared workspaces and workflows, file transfers breeze by quickly so you spend less time setting up and more time getting to work. 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 a 4K Perspective
With a dedicated DisplayPort 1.2, OWC Gemini empowers you to add the fresh, crisp perspective of a 4K display to your workflow. Whether in your home office or on a mobile studio job, seeing your work in full detail is just one connection away. Use it to free up your laptop port, so you can dock in and out quickly and stay mobile.
Reclaim Your Desktop
With multi-drive media dumps, controllers, A/V outputs, and a mess of device cables, it can be hard enough to find space for your notebook let alone room to work. OWC Gemini fights the clutter with a single-cable connection that delivers storage, ethernet sharing, charging power, and 4K 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
With the built-in hardware-based RAID controller, you get speed and security without being dependent on what operating system you are running. 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).
