I'm looking at getting a LaCie 5Big Thunderbolt unit for archiving purposes. I would like to get a second one and use Disk Utility to create a Mirrored RAID Set from both of them so that I have a backup of my data. Both LaCie units would be set to be RAID 0 so that I have maximum space available. Am I able to do what I intend to do?
My next question is, assuming I can set them up as a Mirrored RAID Set, would I then be able to swap out a drive on each of them (one at a time, giving the RAID time to rebuild) to increase storage capabilities?
I'm currently planning on getting two 10TB units as that will supply me with enough storage for quite some time. However, I would like to be able to swap out the smaller drives with larger ones in the future.
