Hardware RAID- Speed, Reliability, Flexibility
The Mercury Gemini utilizes hardware RAID to unleash the full potential of two 3.5-inch 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.
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).
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.
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 a perfect choice.
Stabilize Thunderbolt and USB-C Cables
Active workspaces expose gear to bumps, shoves, or even the random tail wag from a pet. 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 confidence even in the highest traffic environments.
