The Mercury Elite Pro Dual 40TB 2-Bay Thunderbolt 2 RAID Array from OWC / Other World Computing features two bays that each sport a 20TB hard drive to deliver a total raw capacity of 40TB for your Thunderbolt-equipped system.

If you use this drive as a RAID 1, then if changes are made (or files added) to one drive, is the 2nd drive updated as well?
Asked by: Patrick
When the OWC Mercury Elite Pro Dual 40TB 2-Bay Thunderbolt 2 RAID Array (2 x 20TB) is configured to RAID 1, any changes to Disk 1 will automatically be applied to Disk 2, as they are a complete 1:1 copy and will always be identical.

I have this drive array with smaller drives and I would like to replace them with larger drives. How would I do that? What specs do I need for the drives? How do I transfer data from the existing drives? How do I install the new drives? Many thanks!
Asked by: Mitchell
This is not too difficult to do, but you must have a means to back the data to another drive/array, replace the drives with larger ones, then format and create your new RAID array. At that point you can move the data back from your backup.
