Designed for Professionals by 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.

Reliability and Support You Can Count On
Like all OWC drives, the Mercury Elite Pro Quad is built to the highest standards of reliability and performance. Because 100% reliability is always the goal, Mercury Elite Pro Quad is rigorously quality tested, and backed by an OWC 3 year limited warranty and 24/7 customer support.
