Overview

OWC Gemini

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.

OWC Gemini Port Callout

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.

OWC Gemini with Display
OWC MacDrive Software

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).

OWC Dock Ejector

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

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 the perfect choice.

OWC ClingOn

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.

    Easy to setup and operate

    The OWC Gemini Dual-Bay RAID was very easy to setup and get going. The case was easy to open and the drive installation was not difficult. All the screws were in the box for either a 3.5 of 2.5 drive installation. As for the RAID, all I had to do was set on the hardware switch on RAID 1 (the choice I wanted). I connected it to a MAC M2 Air, partitioned and formatted. Done. The thunderbolt cable was in the box. The enclosure has two thunderbolt ports, one I connected to the computer, and the other port is connected to an external drive. There are two USB ports as well. I use to those to connect to other external drives and various other devices. The particular version of GEMINI I have has a display port connection. The nice part of this enclosure is that it is a dock, a drive enclosure, and a RAID.

    I would recommend this product to a friend!

    OWC Gemini - Thunderbolt (USB-C)

    My old WD Velociraptor with thunderbolt 1 and the needed dongle wasn't working well with my M2 Macbook. Swopped both WD Velociraptor 1TB 3.5" drives into the OWC Gemini and they are both running like a charm again with a more modern solution. The extra thunderbolt and two USB3 ports are a nice extra. Would recommend this to a friend.
