The Do-It-All Tool for Digital Workflows

With dual drive bays and seven connectivity ports including an SD 4.0 (UHS-II) 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-inch 7200RPM hard drives or 2.5-inch SATA SSDs. Preconfigured in high-speed RAID 0 mode to deliver maximum throughput from its drives, Gemini offers real-world HDD speeds up to 562MB/s for audio editors/musicians/producers, individual content creators, photographers, small photography studios, and filmmakers working with up to 4K resolutions and compressed codecs. A/V professionals seeking SSDs that start and stay fast over their full capacity can take advantage of the proven reliability of OWC Mercury Extreme SSDs. With sustained RAID 0 speed up to 956MB/s, you can easily handle 8K single and 4K multi sequences, slow motion video, 10 bits footage, and ultra-high-resolution RAW pictures.

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 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. 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. It's also great for sending your files over to a NAS to keep them safely archived.

Gain a 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. 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 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

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).
