High-Performance + Flexible

The OWC Mercury Elite Pro Dual houses two user-supplied drives that can be easily configured in RAID 0, RAID 1**, span, or JBOD/independent modes via the easy-to-use RAID selector switch on the back, while USB 3.0 and Thunderbolt interfaces provide blazing fast access to your data. This feature-packed external drive comes in a durable, heat-dissipating, brushed-aluminum enclosure.

High-Reliability

A blazing fast Thunderbolt chipset unleashes the full potential of two internal drives you choose to install. Get the maximum sustained throughput from your drives with the flexibility of hardware RAID 0, 1, and non-RAID modes to best suit your demanding applications and workflow.

Portability

The OWC Mercury Elite Pro Dual Series is Built to Last, with a quality design and the best components.

Smart Sense

The Compact and Shock-Resistant Design has the Mercury Elite Series going places! In addition, the OWC Mercury Elite Pro Dual series offers two Thunderbolt ports and one USB 3.0 port for easy use with ANY system! The OWC Mercury Elite Pro Dual even includes all needed cables! Power Saving Connection Sensor. A built-in sensor detects when the data cable is disconnected from a Mac or PC's native Thunderbolt or USB interface and automatically spins down the drives to conserve energy during periods of inactivity. Ideal for notebook users who can go mobile without the need to turn it off or unplug the power cord.**

*For RAID 0 or RAID 1 functionality, it is recommended that identical drives be utilized.

**This function is also available through an interface card, provided the card offers hot plug capability. LED and fan will remain on during disk inactivity.

Still Running Fine

Been using this for 8 years mainly as external storage for photos stored in Lightroom, and the drive is still running fine. Can't ask for much more. I've already cycled through some other drives for time machine or other back up purposes, but the OWC one has been rock solid.

I would recommend this product to a friend!

Verified Purchase.

Response from OWC, Support

Wow Casey we are glad to hear the Mercury Elite Pro Dual has lasted 8 years, while we do have some newer models available if you're ever interested in upgrading. We hope the enclosure continues to serve you well, thanks for being an OWC customer!

Strong and silent

I purchased this to replace the OWC Guardian Maximum RAID unit I had bought a few years earlier, primarily for use as an external drive for my 50K images - the main reason being it has the Thunderbolt connectivity I wanted to take advantage of on my iMac 2012 model. It has worked flawlessly in that time, and I am saddened by Apple's decision to kill Thunderbolt altogether (at least that's my interpretation of my new 27" iMac with Retina display having zero Thunderbolt ports). So now it's connected via USB 3, and still humming along like a champ.
