Overview

OWC Gemini

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.

OWC Gemini Port Callout

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

    1. Thunderbolt 2/Thunderbolt compatibility requires a certified Thunderbolt 3 (USB-C) to Thunderbolt 2 (mDP) adapter and a Thunderbolt 2 cable (not included). This configuration provides data transfer at up to 20Gb/s but does not support notebook charging.
    2. Must be connected to host computer via Thunderbolt (USB-C), and cannot be used as a NAS. The Ethernet port provides the host computer with a 2.5GbE network connection over Thunderbolt (USB-C), but it cannot be used to access the drives over the network.
    3. Requires 2.5Gb/s Ethernet compatible hardware components and cabling (Cat 5e cable minimum, Cat 6 or later strongly recommended).
    4. OWC ShuttleOne 1 x NVMe M.2 and U2 Shuttle 4 x NVMe M.2 to 2.5-inch U.2 SSD Adapters sold separately. When installing OWC U2 Shuttles, the OWC Gemini is limited to three drives per shuttle with drive capacities of up to 4TB per drive.
