Workflow and Storage Solutions for Pros
Whether you’re finishing and mastering, creating proxies or working with state-of-the-art VFX and AR, you need dependable tech that keeps pace with your demands. OWC workflow and storage solutions cover every angle, delivering processing speeds up to 2800MB/s1, capacity for all five levels of RAID, and bonus features like the freedom to daisy-chain and hot-swap.

Designed for Professionals
Every detail was considered when designing the Mercury Elite Pro Quad. Built with a heat-dissipating aluminum enclosure, a whisper-quiet fan, and vibration-absorbing feet, the Mercury Elite Pro Quad runs cool and quietly, making it ideal for noise-sensitive environments. Front-facing LEDs provide an instant drive-activity snapshot, while the front panel access lock keeps your drives safe. You can even secure the entire drive with the rear-mounted Kensington compatible lock slot. On top of that, drive-equipped models undergo OWC's multi-hour drive "burn-in" performance certification procedure to ensure that your drive arrives operating properly and ready to perform.

Work with Ultimate Confidence
Active workspaces expose gear to unexpected bumps and shoves. OWC ClingOn custom cable stabilizers (available 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 ultimate confidence even in the highest foot traffic environments.
