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.

Compatible with 2.5" and 3.5" drives, the Mercury Elite Pro Quad's four universal drive bays let users pack up to a massive 80TB of storage. With this level of capacity and drive flexibility, you will not have to compromise when it comes to your storage.

We understand having confidence in gear reliability is paramount to creative professionals. That’s why every ThunderBay undergoes OWC's multi-hour "burn-in" performance certification prior to shipping. This ensures your ThunderBay arrives operating properly and immediately ready for demanding use.

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.
