Hardware RAID: Speed, Reliability, Flexibility
The Mercury Elite Pro Dock utilizes hardware RAID to unleash the full potential of two 3.5″ 7200RPM hard drives. Preconfigured in high-speed RAID 0 mode to deliver maximum sustained throughput from its drives, the Mercury Elite Pro Dock offers real-world speeds up to 773MB/s to handle HD video workflows. If you desire the extra security of mirrored data, you can configure the Mercury Elite Pro Dock in RAID 1 mode. Need more drive flexibility? Set up a span to combine the capacity of the two drives into one huge volume or use the drives as independent volumes.Future Project ReadyYou can customize the Mercury Elite Pro Dock to quickly adapt to project changes and help you stay ahead of deadlines. Install your choice of 2.5” or 3.5” HDDs or SSD and even combine the speed of an SSD with the cost-effective storage capacity of an HDD. With built-in hardware RAID, you have four drive set-up choices:

  • Non-RAID to keep the drives as independent volumes
  • RAID 1 (mirror) for backup reliability
  • RAID 0 (stripe) for optimal performance and maximum speed or use
  • Span to combine the drive capacities into one huge volume for extra-large storage capacities


  • Performance storage: up to 773MB/s
  • Fast connectivity: (2) Thunderbolt 3 ports (Thunderbolt 2/Thunderbolt backward compatible)
  • Speed and storage: hardware RAID controller (RAID 0,1, Span or JBOD/Independent)
  • Easy camera uploads: frontside SD 4.0 (UHS-II) card reader
  • A hub of options: (2) USB 3.1 Gen 1 (Type-A) ports
