Hardware or Software RAID: Speed, Reliability, Flexibility

The OWC Gemini can utilize the built-in hardware RAID controller 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 1 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 2, you can easily handle 8K single and 4K multi sequences, slow motion video, 10 bits footage, and ultra-high-resolution RAW pictures.

Even faster with NVMe SSDs

Make your dream of becoming an editing powerhouse a reality by utilizing the performance of NVMe SSDs. Using software RAID such as SoftRAID (sold separately) you can set both NVMe drives as a RAID 0 for performance up to 1446MB/s 3. This is enough bandwidth to handle demanding media workflows such as 8K video and 6K multicam sequences using advanced 10 bit and 12 bit codecs, high frame rate footage, and ultra-high resolution RAW pictures. You can also use M.2 “blade” style SSDs via adapters like the OWC ShuttleOne and U2 Shuttle 4.

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 5. 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 6. 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 7.

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.
