Product Information


OWC Mercury Elite Pro Quad External Storage Solution

Designed to put the power of choice in your hands, the OWC Mercury Elite Pro Quad packs an unprecedented combination of USB connectivity, universal drive bays, and advanced SoftRAID capabilities into a whisper-quiet aluminium enclosure. Whatever your workflow needs, the Mercury Elite Pro Quad has the flexibility to take your storage capacity, performance, and data security to a whole new level.

The Flexibility of USB-C

The Mercury Elite Pro Quad's powerful USB-C interface delivers 10Gb/s USB 3.1 Gen 2 bandwidth and works with any USB-C or Thunderbolt 3 equipped Mac or Windows PC. Simply connect the Mercury Elite Pro Quad via the included USB-C cable to experience next-level performance. If your computer doesn't feature USB-C connectivity, the included USB-C to USB-A cable brings backward compatibility for machines with legacy USB ports.

Capacity Without Compromise

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

SoftRAID: RAID Made Easy

Harness the full capability of your OWC drive array with the included SoftRAID XT, the most powerful, intuitive RAID management software on the market for macOS and Windows. SoftRAID’s RAID creation and management technology has been finely tuned to perfection with over 20 years of development to provide rock solid protection of your data and optimise drive performance.

Beyond Hardware RAID

SoftRAID provides a level of storage performance that you simply can’t get with hardware RAID. SoftRAID gives you increased power and control over your RAID drives and disks that hardware RAID can’t deliver and doesn’t lock you into technology that you can’t upgrade or expand.

Designed for Professionals by Professionals

Every detail was considered when designing the Mercury Elite Pro Quad. Built with a heat-dissipating aluminium 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.
