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.

    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.

    For more reason than one, this failed to be the solution I was looking for

    I was hopeful this would function as my main dedicated external storage, as the specs look great, but there are a number of issues with this drive you should be aware of before purchasing. 1) It is noisy, very noisy. Every online review said this, and I thought they were exaggerating. They weren't. I've exclusively used external drives from OWC for two decades now, and none are half as loud as this one is. 2) There's no power switch. This wouldn't be a huge concern if it wasn't so loud, but I find myself having to physically unplug it when not in use. 3) When connected to my computer, but unmounted, the drives still randomly spin every couple of minutes. Aside from being noisy, I'm concerned it will lead to early failure as it seems to be creating unnecessary stress on the drives. 4) After not using the drive for a short time, just a minute or two, it semi powers down. Then when I try to access a file on the drive again, it has to power back up and takes about 20-30 seconds to do so. This is hugely detrimental to my workflow and massively slows down the process of editing photos directly on the external drive. I've never had any other past OWC drive do anything remotely similar to this. I was hoping to use this for the next 5-6 years at least, and after just 6 months I'm trying to figure out how I can get rid of this thing. Its various quirks don't inspire enough confidence in the product for me to trust it with my decades of work.

    Response from OWC, Support

    We appreciate the feedback on the 36TB OWC Gemini. We are sorry to hear that you are not fully satisfied with the product. The noise you are hearing in this device is from those HDD drives and not the device itself, the larger the HDD drive the more likely it is to be loud. We have found some success with placing this device on a neoprene pad to dissipate some of that noise as it can be amplified on a hard surface. The drives do power down when they enter sleep mode from inactivity and this can be prevented by not allowing the drives to go to sleep in the settings menu or turning off the sleep setting in general. If you need any additional help with this device please contact our technical support team. https://eshop.macsales.com/Service/
