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.
