OWC Mercury Elite Pro Dual

12.0TB Multi-Interface Performance RAID

Mac / PC / Thunderbolt / USB 3.0 & 2.0
High-Performance, High-Reliability, Portability, and Style are standard for the OWC Mercury Elite Pro Dual Series!
OWC external drives are built to last and have become the "go to" drives for professionals and enthusiasts alike. The OWC Mercury Elite Pro Dual houses two 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.
Outstanding Features
The High-Speed Intel "Cactus Ridge" chipset, combined with some of the fastest SATA drive mechanisms available give the Mercury Elite Pro Dual single-drive transfer rates, exceeding 1250 Megabytes Per Second.
The OWC Mercury Elite Pro Dual Series is Built to Last, with a quality design and the best components, backed up by a Three Year Warranty.
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!
Smart Sense
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.*

*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.
