Second-gen aluminum design with quiet cooling fan

Performance by Design
Reliable hardware RAID maximizes the full potential of two 3.5-inch 7200RPM hard drives in the Mercury Elite Pro Dual. It comes configured in high-speed RAID 0 mode for the maximum sustained throughput from your drives. With speeds up to 407MB/s1, that’s fast enough for HD video workflows. Configure the Mercury Elite Pro Dual in RAID 1 mode for the extra security of mirrored data, set up a span of the two drives, or use them independently.

Performance by Design
Mercury Elite Pro Dual features both high speed USB 3 & eSATA ports to offer the connectivity and versatility to work with your current equipment setup. A second-generation, free-flowing brushed-aluminum chassis with high-performance fan delivers cool, quiet operation. In addition, drive activity LEDs give you an instant snapshot of the status of your RAID, and intelligent power management conserves energy and reduces wear by automatically spinning down the drives when inactive.

Support You Can Trust
