from "Quick removal" to "Better performance" can increase disk performance.
OWC offers the application OWC Disk Performance to help change the Disk
Removal Policy. Changing from "Quick removal" to "Better performance" can
also be changed manually.

4.1 Troubleshooting
• Begin by verifying that the power cable is connected to the OWC Mercury Elite Pro
Dual 3-Port Hub and to a power source. If the power cable is connected to a power
strip, make sure that the power strip switch is in the ON position. Next, verify that
each end of the data cable is properly plugged into the computer and the OWC
Mercury Elite Pro Dual 3-Port Hub , respectively. If you are still having trouble, try
connecting a different Thunderbolt 3 cable and see if the OWC Mercury Elite Pro Dual
3-Port Hub works properly; you can also connect the device to a different computer.
• If one of the drive LEDs (Drive 1 or Drive 2) lights up a solid red, then that drive has
failed, is not fully connected, or is missing. If you purchased the OWC Mercury Elite
Pro Dual 3-Port Hub as an empty enclosure, or the enclosure shipped with drives
installed but is past the three-year warranty period, unmount the disk from the OS,
power off, and replace the drive as outline d in Section 2.3 "Assembly Steps". If the
OWC Mercury Elite Pro Dual 3-Port Hub is configured as a RAID 1 and the rebuild
LED is pulsing, please wait for the rebuild process to complete. If the rebuild LED is
still blinking after more than 48 hours, or if you still need assistance for other reasons,
please contact our Support team.
